S= a/4 + 8u
S - 8u = a/4 (First you subtract 8u from both sides)
4(S - 8u) = a ( Then you multiply both sides by 4)
Final answer:
4(S - 8u) = a
X + 13 = -4
x = -4 - 13
x = - 17
I am thinking it is the first one..solution is -17
The hexagonal prism has a an equation of volume = base * height.
Since we already know the base is 8 sq feet, we can plug in some values and use x as a missing value
40 = 8 * x
Divide by 8
5 = x
X is equal to 5.

The cost of one slice of mushroom pizza is $2.00 dollars. This is solved by subtracting the equations:
X = cheese pizza
Y = mushroom pizza
(3X + 4Y = 12.50)
- (3X + 2Y = 8.50)
______________
2Y = 4.00
Y=2 or a slice of mushroom pizza is $2.00.
