Question

Which of the following is a true statement?
A If n + 14 = -15, then n = -1.07143
B If 14 + n = -15, then n = -1
C If 14 + n = -15, then n = -29.0
D If 14 - n = -15, then n = -1.0
E I don't know

PLEASE ANSWER MY QUESTION ASAP

Answer 1

We need to find a expression that is true. Let's try out every one of them until we get a right answer.

If n + 14 = -15 then n = -1.07143

Replace n with -1.07143.

-1.07143 + 14 = 12.92857

12.92857 does not equal 15.

So, the first option is incorrect.

If 14 + n = -15, then n = -1

Replace n with -1

14 + (-1) = 13

13 is not equal to -15.

If 14 + n = -15, then n = -29.0 

Replace n with -29.0

-29.0 + 14 = -15

This expression is indeed true.

So, the answer to this question is C If 14 + n = -15, then n = -29.0
