Number 9 (What should Brad do to correct the error that he made?)

Mathematics
1 answer:
LenaWriter [7]3 years ago
5 0

The right answer is Option D.

Step-by-step explanation:

Steps done by Brad;

-3(2+w)=-45\\2+w=-15\\w=-17

Brad made the error in first step where he divided both sides by 3; but one left side, he did not put the negative sign.

In order to correct his error, Brad should divide -45 by -3 to get 15.

Therefore;

-3(w+2)=-45\\w+2=\frac{-45}{-3}\\w+2=15

Thus,

Divide -45 by -3 to get 15.

The right answer is Option D.
