Answer:

A. and C.

Step-by-step explanation:

(5•1) - 7

  • We need to calculate inside the parenthesis first.

5 × 1 = 5

  • Then we subtract.

5 - 7 = -2

  • Now, to see which expressions are equivalent to (-2), we can check each option using the same steps.

A.

1 × 5 - 7 = -2

C.

5 ÷ 1 - 7 = -2
