1. a football team gained 4 yards on a play, lost 8 yards on the next play, then gained 2 yards on the third play. write an addition expression to describe the total change of yardage. then determine the sum and explain its meaning

We have been given that the football team gained 4 yards on a play, lost 8 yards on the next play, then gained 2 yards on the third play.

Gain can be represented by plus and loss can be represented by minus sign.

Thus, we have

gained 4 yards means +4

lost 8 yards means -8

gained 2 yards means +2

Therefore, the addition expression to describe the total change of yardage is given by

Now we have

Thus, we have

We got minus sign, which means loss.

Hence, the football team lost 2 yards.

step-by-step explanation:

infinity is the answer

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
