If cindy works 18 hours a week at 5.15 an hour how much did she make for the whole year?

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

To solve the system of equations below, pedro isolated the variable y in the first equation and then substituted it into the second equation. what was the resulting equation? { 5y=10x {x^2+y^2=36

3x + 4y = 5 x- 3y = -7 solve by substitution
