Write an equation to show how many t-shirts t Jenna originally had if "Jenna gave seven t-shirts to her friend and now she has 19."

• t + 7 = 19

• t - 7 = 19

• 19 + 7 = t

• 7 + t = 19

Talen had $60 when he went to the store and now has $25 left. He bought two shirts at one store, and then bought a pair of sunglasses for $15. Write an equation that represents the situation

• 60 - 2x - 15 = 25

• 2x - 15 = 60

• 2x - 60 - 15 = 25

• 25 + 15 + 2x = 60

Solve 25 + 15 + 2x = 60

• 20

• 10

• 15

• 5

Grant mows the lawn for a family down the street. He earns $36 each time he mows the lawn. Write an expression that could be used to find the amount Grant earns moving m times for the family.

• 36 + m

• 36 - m

• 36m

• 36/m

Tessa and Kelsey are running on the track. Tessa runs 6.4 kilometers less than Kelsey. Write an equation for the number of kilometers Kelsey runs, k, if Tessa runs 9.3 kilometers.

• 9.3 + k = 6.4

• 9.3 - k = 6.4

• k - 9.3 = 6.4

• k - 6.4 = 9.3

The output (y) is 8 more than the input (x). Write an equation to show the relationship between the output and the input.

• y = x + 8

• y = x - 8

• y = 8x

• y = x/8
