Question

Select the proper inverse operation to check the answer to 14 + 17 = 31. A. 31 ÷ 17 = 14 B. 31 − 17 = 14 C. 14 − 17 = 31 D. 31 × 14 = 17

Answer 1

the equation is addtion meaning the inverse operation would be subtraction. since 14 and 17 are the parts, the awner would be one of them subtracted from 31. B) 31 - 17 = 14

Answer 2

Answer: B. 31 − 17 = 14

Explanation:

Given sum: 14+17=31

We know that the proper inverse operation to check the answer to a+b=c is

c-a=b or c-b=a [because subtraction operation is inverse of addition operation]

Therefore, for the given sum, the proper inverse operation to check the answer to 14+17=31 is 31 − 17 = 14 or 31 - 14 = 17

Therefore, B,. is the right answer.
