What is the value of x in the equation shown below.
0.25x + 7 = 4(x - 2)
Answer:
x=4
Step-by-step explanation:
0.25x+7=4(x−2)
Use the distributive property to multiply 4 by x−2.
0.25x+7=4x−8
Subtract 4x from both sides.
0.25x+7−4x=−8
Combine 0.25x and −4x to get −3.75x.
−3.75x+7=−8
Subtract 7 from both sides.
−3.75x=−8−7
Subtract 7 from −8 to get −15.
−3.75x=−15
Divide both sides by −3.75.
x=-15/-3.75
Expand -15/-3.75 by multiplying both numerator and the denominator by 100.
x=-1500/-375
Divide −1500 by −375 to get 4.
x=4

Write the slope-intercept equation of the line that passes through the given point and is parallel to the given line.
(−3, 8), x = −3y + 9
Answer:
y= -3yx + 9x - 37
Step-by-step explanation:
Find the Equation Using Slope-Intercept Form
Answer:
y= - (1/3) x + 9
Step-by-step explanation:
y = m x +b === m is slope, b is y-intercept
Solve given equation for y to find parallel slope -- y = - (1/3) x + 3
so parallel slope is - (1/3)
substitute point & slope into equation to find b
8 = - (1/3) (3) + b
b = 9

Maplewood Supply received a $5,270 invoice dated 4/15/10. The $5,270 included $270 freight. Terms were 3/10, 2/30, n/60.
a. If Maplewood pays the invoice on April 27, what will it pay?
b. If Maplewood pays the invoice on May 21, what will it pay?
Answer:
The invoice gets paid after 12 days, so mapplewood will get a 3% discount (3/30, 3% off if paid within 30 days). I assume that Freight doesn't get a discount, so I subtract it from the invoice value:
$5250-$250 (freight)=$5000
Discounted invoice becomes:
$5000-3%*5000(discount)=$4850
Add the freight back to the new invoice:
$4850+$250=$5,100 if paid on April 27
B) the invoice gets paid after 36 days, so the invoice gets paid in full ( n/60; in other words, invoice paid in full if paid within 60 days, therefore $5,250)

Find the volume of the composite solid.
Answer:
80cm3
Step-by-step explanation:
volume of the composite solid=volume of the
pyramid+
volume of the
cuboid
volume of the pyramid=1/3* base area*height
=1/3*5*4*6
=40cm3
volume of the cuboid=base area *height
=5*4*2
=40cm3
volume of the composite solid=40cm3+40cm3
=80cm3

Question
A random sample of SAT scores has a sample mean ofă = 1060 and sample standard deviation of s = 195. Use the
Empirical Rule to estimate the approximate percentage of SAT scores that are less than 865.
Answer:
The approximate percentage of SAT scores that are less than 865 is 16%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 1060, standard deviation of 195.
Empirical Rule to estimate the approximate percentage of SAT scores that are less than 865.
865 = 1060 - 195
So 865 is one standard deviation below the mean.
Approximately 68% of the measures are within 1 standard deviation of the mean, so approximately 100 - 68 = 32% are more than 1 standard deviation from the mean. The normal distribution is symmetric, which means that approximately 32/2 = 16% are more than 1 standard deviation below the mean and approximately 16% are more than 1 standard deviation above the mean. So
The approximate percentage of SAT scores that are less than 865 is 16%.

Which answer is an equation in point-slope form for the given point and slope?
Point (1, 9), Slope: 5
(A) y - 9 = 5(x + 1)
(B) y+9 -5(x - 1)
(C) y-9=5(x - 1)
(D) y-1-5(x +9)
Answer:
Step-by-step explanation:
Point-slope equation for line of slope m that passes through (x₀,y₀):
y-y₀ = m(x-x₀)
In your case, m=5 and (x₀,y₀)=(1,9):
y-9 = 5(x-1)

Using only addition what is 20 - 9 + 8 -7
Answer:
12
Step-by-step explanation:
Answer: 12
Step-by-step explanation:
I don't know if you mean using the Complements Method but I really wouldn't recommend using this method for all problems unless your teacher asked you to specifically.
Here is how to:
1. take the "complement" of the number we are subtracting (The "complement" is the number to add to make 10 (or 100, 1000, etc, depending on how many digits we have)
2. add it to to the number we are subtracting from
3. discard the extra "1" on the left
If you mean to do it mentally, think about it like this:
20 + (-9) = 11 You are essentially adding negative nine to twenty, not subtracting nine. If you want to see this better, try using a number line. When you add a negative number, you move to the left on the number line.
Same thing with 8 + (-7) = 1
You are adding negative seven to eight.
All that is left to do is adding both of the results together, and you get twelve.
11 + 1 = 12
