Answer:
The unit rate is 0. 14 miles per minute.
Hence, option a is correct.
Step-by-step explanation:
Given
Running of 5/4 a mile in 9 minutes.
To determine
The unit rate = ?
Given that the running 5/4 a mile in 9 minutes.
i.e.
Miles covered in 9 minutes = 5/4 or 1.25 miles
Miles covered in 1 minute = 1.25/9
= 0. 14 miles per minute
Therefore, we conclude that:
The unit rate is 0. 14 miles per minute.
Hence, option a is correct.
Remove parentheses
3m - 7m+12 = 2 m-3
collect like terms
3m-7m-12 = 2m-6
move terms
-4m - 12 = 2m-6
collect the like terms and calculate
-4m-2m = -6+12
divide both sides by -6
-6m=6
m= -1
