Three friends went to Staples for school supplies. Anna bought two notebooks, one pencil, and three
binders for $14.50. Josh bought one notebook, four pencils, and one binder for $7.50. Alex bought 3 notebooks,
two pencils and two binders for $14.50. Find the price of each item by solving a system of three equations
algebraically
Answer:
A pencil costs $0.50
A binder costs $3.00
A notebook costs $2.50
Step-by-step explanation:
Represent Notebook with N, Pencil with P and Binder with B
For Anna:.
2N + P + 3B = 14.50
For Josh:.
N + 4P + B = 7.50
For Alex:
3N + 2P + 2B = 14.50
Required
Solve for N, P and B
Make N the subject in the second equation
N + 4P + B = 7.50
N = 7.50 - 4P - B
Substitute 7.50 - 4P - B for N in the first equation
2N + P + 3B = 14.50
2(7.50 - 4P - B) + P + 3B = 14.50
Open Bracket
15.0 - 8P - 2B + P + 3B = 14.50
Collect like terms
3B - 2B + P - 8P = 14.50 - 15.0
B - 7P = -0.50
B = 7P - 0.50
Substitute 7.50 - 4P - B for N in the third equation
3N + 2P + 2B = 14.50
3(7.50 - 4P - B) + 2P + 2B = 14.50
22.50 - 12P - 3B + 2P + 2B = 14.50
Collect Like Terms
2P -12P + 2B - 3B = 14.50 - 22.50
-10P - B = -8
Multiply through by -1
10P + B = 8
Recall that B = 7P - 0.50
10P + B = 8 becomes
10P + 7P - 0.50 = 8
17P - 0.50 = 8
17P = 8 + 0.50
17P = 8.50
Divide through by 17
P = 8.50/17
P = 0.50
This implies that a pencil costs $0.50
Substitute 0.50 for P in B = 7P - 0.50
B = 7 * 0.50 - 0.50
B = 3.50 - 0.50
B = 3.00
This implies that a binder costs $3.00
Substitute 3.00 for B and 0.50 for P in N = 7.50 - 4P - B
N = 7.50 - 4 * 0.50 - 3.00
N = 7.50 - 2.00 - 3.00
B = 2.50
This implies that a notebook costs $2.50

can someone please help just for a sec and help me with these questions. -7x = -91 and
0.5x + 1.75 = 10 and last one is
0.75h + 3 = 12
Answer:
13, 16.5, 12
Step-by-step explanation:
-7x= -91 divide both sides by -7 to isolate x
[tex]\frac{-7}{-7} x=\frac{-91}{-7}[/tex] any number divided by itself like in -7/-7 =1
x=13
0.5x + 1.75 = 10 subtract 1.75 from both sides
0.5x +1.75-1.75 =10 -1.75
0.5x = 8.25 divide by 0.5 both sides
[tex]\frac{0.5}{0.5} x=\frac{8.25}{0.5}[/tex]
x=16.5
0.75h +3=12 subtract 3 from both sides
0.75h = 12-3 divide both sides by 0.75
[tex]h= \frac{9}{0.75}[/tex] = 12
The number of phone calls your business receives daily has mean 20.6 and standard deviation 4.4. You record the number of phone calls received over the next 100 days and compute the average. The probability that is more than 21 is:_____
a. approximately 0.9186.
b. approximately 0.1814.
c. approximately 0
d. approximately 0.464
Answer:
The correct option is b.
Step-by-step explanation:
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.
Then, the mean of the sample means is given by,
[tex]\mu_{\bar x}=\mu\\[/tex]
And the standard deviation of the sample means is given by,
[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]
As the sample size is large, i.e. n = 100 > 30, the Central Limit Theorem can be used to approximate the sampling distribution of sample mean number of phone calls your business receives daily.
Compute the probability that the average number of phone calls your business receives daily is more than 21 as follows:
[tex]P(\bar X>21)=P(\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}>\frac{21-20.6}{4.4/\sqrt{100}})\\\\=P(Z>0.91)\\\\=1-P(Z<0.91)\\\\=1-0.81859\\\\=0.18141\\\\\approx 0.1814[/tex]
Thus, the correct option is b.

You are beautiful. You are amazing. You are wonderful. You are perfect just the way you are. Never worry about the way people think about you. Only worry if you like you. You are the most important person to yourself. Just be yourself. No can tell you who you can be. You are truly perfect just the way you are. Never tell yourself you are not good enough, you are enough. Never tell yourself "I'm ugly" you are beautiful. Never let yourself down.
We are acting like everything is alright, when we actual want to break down and cry. We are acting like we are brave, when we are scared and afraid. We are acting like when can do anything, when we think we can't do anything. We are acting like we love those who hate us because we are to afraid to say the truth. We are acting like people who are to afraid to show who they really are. We are acting like life is a fairytale, but it's actual a nightmare. We are acting like we are the most happiest people, but really we just want to curl up inside. We are acting like we want to stay, when we want to run away. We are acting like we a doing just fine, When we are about to give up. We need to change, don't worry about those who hate. Don't worry about the way you look. Don't worry about who you really are. Just be yourself. Just relax. Just the real person you our. It doesn't matter what they say. The only thing that matters is if you like you the real you, not someone you are trying to pretend to be, but the real you.
There is always love, when there's only hate. There is always hope, when hope seems lost. There is always someone, when we have no one. There is always a light, when in there is darkness. There is always a way out, when we are stuck. There is always happiness, when we feel only sadness. There is always angels, when we only see demons. There is always someone to talk to, when there seems no one to talk to. There is always beauty, when things get ugly. There is always hope. There is always love. There is always someone. There is always a light. We might want to give up. We might want to lose the fight. We might want to stop trying. We might want to run away. No matter what, no matter what's happening right now, no matter if there seem like everything is falling apart or there is just a feeling that you need to give up. Always remember there is someone out there who needs you. There is always someone to talk to. There is always hope. Don't give up, don't give up. As there is always love, hope and happiness.
Sometimes in life we need a dose of happiness, sometimes we need someone to talk to, sometimes we need someone to hold on to, but sometimes we just wanna be alone, sometimes we need no one to talk to or hold. Their are those with nothing at all and there are those who have everything, but sometimes we have nothing but still everything, sometimes we have everything but nothing. Sometimes we wonder, sometimes we don't. Sometimes we try but fail and sometimes we don't try but yet succeed. Sometimes we cry, sometimes we get mad. Sometimes we do wrong, sometimes we do right. Sometimes we hate, sometimes we love. Sometimes we get our heart broken, sometimes we break peoples heart. Sometimes we tell the truth, but we are still lying. Sometimes we just need to relax but yet we can't. Sometimes we need quiet in a big city. Sometimes we are afraid of the unknown and sometimes we are not. Sometimes we discover. Sometimes we challenged. Sometimes we fall in love. Sometimes we find joy in a room of sadness. Hope this helps, have a wonderful day.

✅I STINK THEREFORE I HAM
Step-by-step explanation:
A: m<BOD = 57° + 38° = 95°
O: m<AOC = 18° + 57° = 75°
R: m<AOD = 18° + 57° + 38° = 113°
T: m<FUG = 31°, since, FUG ≅ HUI, therefore, m<HUI = 31°
m<FUI = 123°
m<GUH = m<FUI - (m<FUG + m<HUI)
m<GUH = 123° - (31° + 31°)
m<GUH = 61°
M: m<GUI = m<GUH + HUI
m<GUI = 61° + 31°
m<GUI = 92°
E: m<EUH = 129° (given)
m<EUF = m<EUH - (m<FUG + m<GUH)
m<EUF = 129° - (31° + 61°)
m<EUF = 37°
F: m<EUI = m<EUF + m<FUG + m<GUH + m<HUI
m<EUI = 37° + 31° + 61° + 31°
m<EUI = 160°
K: since <JAK ≅ <MAN, and m<JAK is given as 30°, therefore,
m<MAN = 30°
I: m<JAM = 110° (given), m<JAK = 30° (given)
Since <KAL ≅ <LAM, therefore,
m<LAM = ½(m<JAM - m<JAK)
m<LAM = ½(110° - 30°)
m<LAM = 40°
S: m<KAM = m<KAL + m<LAM
Since <KAL ≅ <LAM, therefore,
m<KAM = 40° + 40°
m<KAM = 80°
H: m<JAN = m<JAK + m<KAL + m<LAM + m<MAN
m<JAN = 30° + 40° + 40° + 30°
m<JAN = 140°
N: m<KAN = m<KAL + m<LAM + m<MAN
m<KAN = 40° + 40° + 30
m<KAN = 110°

Answer:
[tex]\mathbf{\dfrac{dV}{dt} = \pi \bigg ( \dfrac{{t}+2}{4\sqrt{t}}\bigg)}[/tex]
Step-by-step explanation:
Given that:
The radius of a right cylinder is given by √(t+6) and its height is 1/6√t;
The volume of a given circular cylinder is:
[tex]V = \pi r^2 h[/tex]
[tex]V = \pi(t+6) \bigg ( \dfrac{\sqrt{t}}{6}\bigg)[/tex]
[tex]V = \pi \bigg( \dfrac{t^{3/2}}{6}+ \sqrt{t} \bigg)[/tex]
[tex]\dfrac{dV}{dt} = \pi \bigg ( \dfrac{3 \sqrt{t}}{12}+ \dfrac{1}{2\sqrt{t}} \bigg)[/tex]
[tex]\dfrac{dV}{dt} = \pi \bigg ( \dfrac{3t}{12 \sqrt{t}}+ \dfrac{6}{12\sqrt{t}} \bigg)[/tex]

Define a variable and then write and solve an equation. (Use the 5-D Process to help you, if needed.) Write your solution as a sentence.
Answer: 16 and a half weeks so maybe put 16
that's the answer because she will save $4 per week 4 x 16 is 86 to 87
that's why i say and a half because it not exactly 87 its 86 so 16 and a half

The inequality that the graph has shown is
y < 2x - 3
Option B is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
From the graph, we have the following coordinates.
(0, -3) and (1.5, 0)
The coordinates can be found in the following inequalities.
Now,
y < 3x + 1
y = 3x + 1
When x = 0, y = 1
This is not possible.
y < 2x – 3
y = 2x - 3
When x = 0, y = -3
This is possible.
y > 2x - 3
y = 2x - 3
When x = 0, y = -3
This is possible
The shaded portion of the graph is more on the negative y-axis.
So,
y < 2x - 3.
Thus,
The graph given has shown y < 2x - 3.

A bank teller has 47 $20 and $5 bills in her cash drawer. The value of the bills is $490. How many $20 bills are
there?
Answer:
A bank teller has 47 $20 and $5 bills.
The value of the bills is $490.
Number of $20 bills --> x
Number of $5 bills --> y
x + y = 47 --> x = 47-y
20x + 5y = 490 --> 20x = 490-5y
so
20(47-y) = 490 -5y
940-20y = 490-5y
940-490 = -5y+20y
15y = 450
y= 30
so
x = 47-30
x = 17
IN TOTAL --> 17 $20 bills and 30 $5 bills.

x = 17 $20 bills
y = 30 $5 bills
General Formulas and Concepts:
