There are 4 semi- trailer truck park a line at the stop. after the first truck, each in the line weights 2 tons more than the truck before it. the truck weight a total of 32 tons. how many pounds does each truck weight?

Let's say the first truck weighs x tons

Then, the weight of 2nd truck = x+2 tons

The weight of 3rd truck = (x + 2) + 2 = x+4 tons

The weight of 4th truck = (x + 4) + 2 = x+6 tons

Total weight of 4 trucks:

x + (x+2) + (x+4) + (x+6) = 32

which can be solved easily to give x = 5

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!
