Question

For questions 7 and 8, combine like terms to create an equivalent expression 7) 7c +24 - 19 + 5c - 2c 8) 9f - 4f - 17 + 10 - 2f

Answer 1

Number 7= 11c+5

Number 8= 3f-7

Answer 2

Explanation:

7) 7c +24 - 19 + 5c - 2c

The unknown term is c. We would rearrange the expression such that all the terms containing c are together and simplified and all the constants are also to together. It becomes.

7c + 5c - 2c + 24 - 19

= 10c + 5

= 5(2 c + 1)

8) 9f - 4f - 17 + 10 - 2f

We would collect the like terms. Terms containing the unknown, f would be made to stand together while the constant will also be together. It becomes

9f - 4f - 2f - 17 + 10

3f - 7
