five times the difference of a number and 7

Answer 1

the difference of five times a number and 7

Step-by-step explanation:

it wouldn't be the first one because that means 5x+7 (a sum means you are adding)

it wouldn't be the last one because that means 5(x-7) or 5x-35

the second one means 5x-7, therefore, it's the correct answer
