Answer 1

Answer:
`(1)/(2) I+7`

Explanation:

marta # books =
`?`

lucy # books =
`I`

Marta has 7 more books than lucy. This means whatever lucy has, marta has 7 more of:

`I + 7`

then, marta also has half as many books as lucy meaning the final expression is:

`(1)/(2) I+7`

Answer 2

M= 1/2(x)+7

Explanation:

Let M = Martha.

Let X = Number of Lucy's blocks.

Martha has half the amount as Lucy - 1/2(x)

Then 7 more than that - 1/2 (x) + 7
