Answer:
<u>given:</u>
to find the output, replace x with the given integer.
solve:
2 + m- 1 + m
Step-by-step explanation:
3m +1 -m
Combine like terms
3m-m +1
2m +1
We can split the m's
m+m +1
And we can rewrite 1 as 2-1
m+m+2-1
m+2+m-1
Rearranging the order
120/3 =40
40 ft = 1 inch
so 40 ft/in is correct answer
