Answer:
2.93
Step-by-step explanation:
3.15×7/100=0.2205
3.15-0.2205=2.9295
The cost of the jeans before tax $2.9295
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
For given example,
Let 'a' be the original price of the jeans.
Let 'b' be the price of the jeans with tax.
then, b = a + tax
Juan paid $3.15 in tax for the jeans.
The sales tax on a pair of jeans is 7 percent.
First we find the tax on a pair of jeans.
⇒ tax = b × 7%
⇒ tax = 3.15 × (7/100)
⇒ tax = $0.2205
We need to find the cost of the jeans before tax.
Here, b = $3.15, tax amount = $0.2205
⇒ b = a + 0.2205
⇒ 3.15 = a + 0.2205
⇒ a = 3.15 - 0.2205
⇒ a = $2.9295
Therefore, the cost of the jeans before tax $2.9295

f(x) = 4/5 x - 2
Find f(3)
Answer is a fraction
Answer:
2/5
Step-by-step explanation:
f(x) = 4/5 x - 2
Let x=3
f(3) = 4/5 *3 - 2
=12/5 -2
=12/5 -10/5
= 2/5
Write an equation for the line that passes through (4, 5) and (6, 7).
|
Answer:
The equation in slope-intercept form would be y=1x+1
Step-by-step explanation:
We can use the slope formula,
m=y2-y1/x2-x1
m=7-5/6-4
m=1
plug in m for y intercept or "b" and choose either points to sub. for the x & y
I am going to choose the (6,7)
7=6(1)+b
7-6=6-6+b
b=1
Our "b" is equal to 1 and just add in the points to the slope formula y=mx+b
HE is 1/3 the length of HG , HE=x-3 and HG=4x-15 find HE
Answer:
x=24
Step-by-step explanation:
HE= 1/3(HG)
x-3=1/3(4x-15)
3x-9=4x-15
-x=-24
x=24
Answer:
HE=3
Step-by-step explanation:
Equations
With the data provided, we can set up an equation. Then we need to solve the equation. Finally, we use the just-found value of x to calculate HE.
Data:
HE=1/3 HG
HE=x-3
HG=4x-15
Replacing the last two equations in the first:
x-3=1/3(4x-15)
Multiply both sides by 3:
3(x-3)=4x-15
Operate:
3x-9=4x-15
Moving x's to the left and numbers to the right:
3x-4x=-15+9
Joining like terms:
-x=-6
Multiply by -1:
x=6
Since HE= x-3:
HE=6-3
HE=3
Every week I buy four 2-litre bottles of lemonade whilst shopping at my local supermarket. Last week the bottles on the shelf were limited edition “2.5 litres for the price of 2 litres” bottles, and the supermarket also had a “buy 3 bottles, get another one free” offer.
In terms of cost per litre, by what percentage was the cost of my four bottles of lemonade lower than usual last week?
Answer:
40%
Step-by-step explanation:
Every week you he buys 4 number of 2 Litres bottle of lemonade.
Thus, let's say cost of each bottle is X.
This means he total cost is 4X
Now, total litres = 4 × 2 = 8 litres
Thus, cost per litre = 4X/8 = ½X
Now, we are told that Last week the bottles on the shelf were limited edition “2.5 litres for the price of 2 litres” bottles ".
This means that now, it is cheaper.
However, the supermarket also had a “buy 3 bottles, get another one free” offer.
Now since he buys 8 litres weekly, now since it's 2.5 L bottle, he will buy 3 since he will be given 1 free for every 3 he buys.
Thus, total litres he is paying for = 2.5 × 3 = 7.5 litres
Thus, cost per bottle is; 3X
Since he is getting 1 bottle free, then total bottle he gets is; 7.5 L + 2.5 L = 10L
Thus;
cost per litre is now; 3X/10
Difference in costs per litre is;
½X - 3X/10 = X/5
percentage of the cost of four bottles of lemonade lower than usual last week = (X/5)/(½X) × 100% = 2/5 × 100% = 40%

Solve the absolute value equation 4 − |x| = 1
Answer :SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)
Step 1: Isolate the absolute value expression.
Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.
Step 3: Solve for the unknown in both equations.
Step 4: Check your answer analytically or graphically.
Step-by-step explanation:
Answer:
x can equal 5 or -5 since absolute value changes everything into a positive number.

Jose bought seven shirts for an average of $12 each and five pair of jeans for an average of $32 each. How much did he spend in total for his clothes?
Answer:244
Step-by-step explanation:
Well first I took 7 and 12 multiplied them to get 84 and the added 32 by 5 by multiplying them, To 84 and these are averages so they aren’t exacts and it gave me 244
Answer:
244
Step-by-step explanation:
12+12+12+12+12+12+12=
24+24+24+12=
48+36= 84
32+32+32+32+32=
64+64+32=
128+32= 160
160+84=244
or
12*7= 84
32*5= 160
160+84=244

Solve the equation below for x.
cx-4=7
A. x=c/3
B. x=3/c
C. x=11/c
D. x=c/11
Answer:
x = 11/c
Step-by-step explanation:
Solve for x:
c x - 4 = 7
Hint: | Isolate terms with x to the left-hand side.
Add 4 to both sides:
c x = 11
Hint: | Solve for x.
Divide both sides by c:
Answer: x = 11/c
find the measures of arc FBD
Answer:
Option (4)
Step-by-step explanation:
[tex]m(\widehat{FC})[/tex] = 180° [FC is the diameter]
[tex]m(\widehat{FC})=m(\widehat{FB})+m(\widehat{BC})[/tex]
180° = 125° + [tex]m(\widehat{BC})[/tex]
[tex]m(\widehat{BC})=180-125[/tex] = 55°
[tex]m(\widehat{FBD})=360-m(\widehat{FED})[/tex]
[tex]=360-[m(\widehat{FE})+m(\widehat{ED})][/tex]
[tex]=360-[m(\widehat{BC})+m(\widehat{ED})][/tex] [Since [tex]m(\widehat{FE})=m(\widehat{BC})[/tex] arcs created by vertical angles]
[tex]=360-(55+56)[/tex]
= 249°
Therefore, Option (4) will be the answer.

Step-by-step explanation:
multiply each number of magazines by the frequency
0*13=0
1*9=9
2*19=38
3*8=24
4*5=20
5*2=10
6*4=24
Then add them all up,
9+38+24+20+10+24=125
Since there are 60 households, divide by 60
125/60= 2.083333 or 25/12
