Answer:
im guessing D
Step-by-step explanation:
So 2/3=x/(3x+y)
multiply both sides by 3x+y
(2(3x+y))/3=x
(6x+2y)/3=x
multiply by 3
6x+2y=3x
subtract 6x form both sdies
2y=-3x
-3x=2y
the ratio of x to y is
-3:2
(x-4)(x-4)
=x^2-4x-4x+16
=x^2-8x+16
it’s +16, not negative. he forgot that when you add two negatives together, it becomes positive.

Step-by-step explanation:
0.40x + 55 = 0.15x + 80
0.40x - 0.15x = 80 - 55
0.25x = 25
x = 25 / 0.25
x = 100 minutes <=
