A. (2+9)x2
B. 10x3-6
C. 9x5+7
D. 9(12÷2)

Answer 1

left side = 52

9*5 + 7 = 52

So its C.

Answer 2

Hi!

First, solve the first part of the equation.

8 * 7 - 4 = 52

So the second part of the equation should equal 52.

• A. (2 + 9) x 2 = 22
• B. 10 x 3 - 6 = 24
• C. 9 x 5 + 7 = 52
• D. 9(12/2) = 54

8 * 7 - 4 = 9 * 5 + 7

The answer is C. 9x5+7

Hope this helps! :)
