Answer:

Step-by-step explanation:
2)
a) elimination method
b) substitution method
c) substitution method
For the first part we can elimate the y variable by subtracting the equations. We can then find the value of x.
For the second part we can substitute y as 2x+5 in the second equation and solve for x.
For the third part we can substitute y as 4x+3 in the first equation and solve for x.
3)

1. y₁ = 70x
2. y₂ = 55x
Solve y₁ - y₂ for x = 11.
Answer:
59 inches
Step-by-step explanation:
a square has 4 equal sides
if the sum of all sides(perimeter) is 236 you can do the inverse of that and divide by 4
so your answer should be 59
