Solve the system of equations algebraically show all of your steps y=x^2+2x y=3x+20 is it x=2.8 and y=28.5?

If y = x^2 + 2x and y = 3x + 20 

Then 

x^2 + 2x = 3x + 20 

x^2 - x - 20 = 0 

(x - 5)(x + 4) = 0 

x = 5, - 4 

For x = 5, y = 3(5) + 20 = 35 

For x = - 4, y = 3(-4) + 20 = 8 

(5, 35), (-4, 8)

2015 they have a perecent

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
