Chad creates a solar system model in his science class. the model sits on a 7 and 3/4 pound board. the entire model. including the board weighs 12 and 1/2 pounds how many pounds does chad solar system model weigh?

i will mark !

To find out how much the solar system weighs, you need to do 12 1/2 - 7 3/4

12.5 - 7.75 = 4.75

So, the solar system weighs 4.75 or 4 3/4 pounds.

are you an artist's daughter? cuz dang you a fine piece of art, girl.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
