. The number of quarters Penelope has is double the number of quarters Barrett has
The total number of quarters they have is 60
What is x, the number of quarters Barrett has?

answer:

125 yards

explanation:

75+50=125. that is my answer

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

im not preaty sure about that

step-by-step explanation: ax^2+bx+c=0= these nuts
