Answer:
, x = 6 ton
Step-by-step explanation:
The truck can be filled with a total of 20 ton.
There are already 14 ton inside the truck, so if we call x the weight of goods that we can still add into the truck, we know that (x+14) must be equal at most at 20. Therefore, the inequality becomes:

Solving it, we find

which means that the most amount of goods that could be added to the truck is 6 tons.
So 1 and 1/2 divided by 1/8. That’s the same as 3/2 divided by 1/8.
Keep change flip.
3/2 x 8/1
24/2= 12
