16. A phone company charges $0.20 per minute on long distance call. Every call is
billed an additional $0.75 service fee. Write
an inequality that represents the number of
minutes you can talk for a maximum of $5.00

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
