Which equation is true?
i. 56 ÷ 4·7 = 82 ÷ (11 + 5)
ii. (24 ÷ 8 + 2)3 = (42 + 9)2
a. i and ii
b. ii only
c. i only
d. neither i nor ii

D. Neither 1 nor 2

Step-by-step explanation:

There's really no explanation other than when you use pemdas on both sides to solve and see if they're equal, neither problem was.

the answer is 1/4

step-by-step 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
