Question

A football team gained 5 yards and then last 7 yards. What real number represents the teams position relative to its original position

Answer 1

`\boxed{-2}}`

Explanation:

Think of this situation as a number line in which the team starts at 0 yd.

Gaining yards is the positive direction and losing yards is negative.

Start at 0 yd and go 5 yd to the right. You are at +5.

Then go 7 yd left. You end up at -2.

+5 – 7 = -2

`\text{The real number that represents the team's position relative to its original position is $\boxed{\mathbf{-2}}$}`
