4. Asa has one piece of wire that is 3m+5 inches long and another piece of wire that is 4m-2 inches long. Write and simplify an expression for the total number of inches of wire.

1. 39 km/hr

2. $235

3. 16

4. 7m+3 inches

Step-by-step explanation:

1. Original speed of car: x km

x+21=60

x=39

original speed: 39 km/hr

2. Amount that the freshman class raised: x

2x+85=555

2x=555-85=470

x=235

Amount that the freshman class raised: $235

3. Number: x

5x-9=71

5x=71+9=80

x=16

The number: 16

4.

3m+5+4m-2

= 3m+4m+5-2

=7m+3 inches
