A truck isn’t carrying 3 cars weighing an average of 3,000 pounds each. What is the total weight in tons of the cars on the truck?

4.5 tons.

Step-by-step explanation:

We do 3(amount of cars)x3000(weight of each car) and get 9000 pounds. A ton is 2000 pounds so we divide 9000 by 2000 and get 4.5 tons

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
