Question

10. A football team gains an average of 7 yards per play How many yards have they gained after 2 plays? Write a number sentence to show your answer.

Answer 1

Let's define the following

`x\text{ = Number of plays}`
`y\text{ = Total number of yards gained}`

Then the expression would be:

`y=7x`

For x = 2:

`y=7\cdot2\rightarrow y=14\text{ yards}`

The total number of yards gained is 14
