What does m equal 2+2m=6
Lorico [155]
2 + 2m = 6 equals m = 2.

First, 
subtract 2 from both sides. Your problem should look like: 2m = 6 - 2.
Second, simplify 6 - 2 to get 4. Your problem should look like: 2m = 4.
Third, divide both sides by 2. Your problem should look like: m = \frac{4}{2}
Fourth, simplify \frac{4}{2} to 2. Your problem should look like: m = 2, which is the answer.

Someone drove 20 miles in 24 minutes at this rate how many miles did they drive in 6 minutes
nikklg [1K]
Distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t 
r = 20mi/24min
= 0.833333 mi/min.

d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles
