b=1,2
c=6
a=5
d=10
here is my reason for getting all this answers because they are corresponding angles.
There are 2000 pounds in one ton, so to find the amount of pounds in a set amount of tons, all we need to do is multiply the amount of tons by the amount of pounds in one ton.
12 * 2000 = 24000
There are 24,000 lbs in 12 tons.
