Runner #1's distance (in miles) with time (in minutes) is d= 1/15t. What is the Pace of the runner?

Runner 1 is going 1 mile per min.

true

explanation:

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

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

i'm not really sure how to answer that
