Given:
The expression is

To find:
The value of the given expression when y=-5.
Solution:
We have,

Putting y=-5, we get




Therefore, the value of the given expression is 50 when y=-5.
Answer:
The solution is 
Step-by-step explanation:
we have

Solve for x
Distribute right side
Remember that



Combine like terms right side

Adds 80 both sides


Divide by 17 both sides

Rewrite

Answer:
8x-3
Step-by-step explanation:
The total perimeter is the length of all the sides of the triangle added together, in this case that is 11x+1. In order to get the length of the one side by itself subtract the other two side lengths from the perimeter. (11x+1)-(x+5)=10x-4. (10x-4)-(2x-1)=8x-3.
It will take him 10 because 125*10 is 1250(12.50)
