Volume of rectangular prism
= W * L * H
W = 7, L = 6, H = 6
Multiply them together
Solution: 6 * 6 * 7
X=-3X=2 —> move the variable to the left handed side and change its sign
-2x=2 —> collect like terms
Divide both sides of the equation by -2 and your answer is x=-1
Answer:
$45.15
Step-by-step explanation:
When you are dealing with questions with percents in them—like this one—you have to turn the percent into a decimal. To make 7.5% into a decimal, you move the decimal point 2 spaces to the left. So, 7.5% is also 0.075.
Now, we have to use this formula for these types of questions:
x + x(y)= the price with tax (or markup)
So, we can substitute the variables.
42+42(0.075)=the retail price
42(0.075)=3.15
42+3.15=45.15
So, the retail price will be $45.15
