Question

An actor gained 20 pounds for a part and then loses 15 pounds during the filming of the movie to go along with the story describe each situation and find the sum and explain its meaning write an additional expression

Answer 1

We are given statement " gained 20 pounds and loses 15 pounds".

Note: We take plus or positive sign for gain word and we take minus or negative sign for the loses word.

Gained 20 means +20.

Loses 15 mean -15.

Therefore, we can setup an expression as:

+20 -15.

20 is a positive number and 15 is a negative number.

Because we have opposite signs of numbers, we would subtract them.

20-15 = 5 pounds.
