Step-by-step explanation:

A football team has four chances with the ball to gain ten yards and keep going to try to make a touchdown. A team gained 7 yards, lost 2, gained 4, and lost 1.

Answers

7 - 2 = 5

5 + 4 = 9

9 - 1 = 8

Sp the total yards they moved was 8 yards.

Hope I helped ya!

So, if losing yards represented by negatives and gaining yards is represented by positives, the equasion whould look like this:
7+(-2)+4+(-1)

The assosiative property tells us that we can group numbers together, like this:
7+4+(-2)+(-1)

And if it helps, add parentheses like this:

(7+4)+(-2)+(-1)

And solve those first:
(11)+(-2)+(-1)

And solve -2+-1
(11)+(-3)

And that equals:
-8

Hope this helps you out!
