Answer:
You can take this equation into two approaches.
#1 subtracting 4x from both sides:
-3x+10=4x-20 (subtract 4x from each side)
-7x+10=-20 (then subtract 10 from each side)
-7x=-30 (then divide by -7 to get x by itself)
x=30/7
#2 Add 3x to both sides:
-3x+10=4x-20 (Add 3x to both sides)
10=7x-20 (then add 20 to each side)
30=7x (divide both sides by 7)
30/7=x
Either way you do it you will get x=30/7 as your answer.

The rate of change in this situation is 3 to 1. Every hour you spend running you are able to advance three miles. 2 hours = 6 miles 3 hours = 9 miles 4 hours = Mindblown+ 12 miles.
Hope this Helps! :)

Since one ton is 2000 pounds, 2.25 tons is equal to 4500 pounds. Now do
