Step-by-step explanation:

A square does not have a diameter so I am assuming that a side length is 9. If that is true all you must do is multiply 9x9x9

What is the value of x when y equals 2 in the equation y equals x over 4 - 7

Alex

The value of x when y = 2 is x = 36

Step-by-step explanation:

The equation that we have in this problem is:

$y=\frac{x}{4}-7$

In order to find the value of x when y is equal to

y = 2

We need to re-arrange the equation making x the subject.

We proceed as follows:

1) We add +7 on both sides:

$y+7=\frac{x}{4}-7+7\\y+7=\frac{x}{4}$

2) Now we multiply both sides by 4:

$4(y+7)=\frac{x}{4}\cdot 4\\x=4(y+7)$

3) Now we can substitute y = 2 and find the value of x:

$x=4(2+7)=4(9)=36$
