What is the y coordinate of the point in the standard (x, y) coordinate plane at which the 2 lines y=x/2 =3 and y=3x-2

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

tip $2.90

total $17.40

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
