Answer:

x = -2

x=-12

Step-by-step explanation:

5 | x+7| +14 = 39

Subtract 14 from each side

5 | x+7| +14-14 = 39-14

5 | x+7| = 25

Divide each side by 5

5 | x+7| /5 = 25/5

| x+7| = 5

Make two equations, one positive and one negative

x+7 =5 x+7 = -5

Subtract 7 from each side

x+7-7 = 5-7 x+7-7 = -5-7

x = -2 x=-12

While watching a football game, Jordan decided to list yardage gained as positive integers and yardage lost as negative integers

koban [17]

Answer:

There is a loss of 2 yards.

Step-by-step explanation:

To find the overall gain or loss, we add or subtract there values.

Initially, we have 0 yards.

Records 14, so 0 + 14 = 14, that is, for now a gain of 14

Then loses 7, so 14 - 7 = 7, for now a gain of 7.

Then, 7 - 9 = - 2, so in all, there is a loss of 2 yards.
