Suppose u= {1,2,3,4,5,6,7,8) is the universal set, and p= {1,3,5,7). what is p'?
2,4,6,83
{1,2,3,4,5,6,7,8
1,3,5,73
1,3,5,7,8

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
