Question

while holding her cat, Mya steps on a scale, the scale reads 127 pounds. Alone, Mya weighs 112 pounds. Write an addition equation to find the weight of Mya's cat.

Answer 1

127+(-112)=15

Explanation:

If you subtract 112 from 127, you can find the difference. Since 112 is Mya's weight, and the total is 127, we need to find out how much weight is left over after we take away Mya's weight, which would be the cat's weight. So if you follow the expression, which is 127+(-112), you would get a sum of 15 pounds. Since this is an addition problem, the expression would be 127+(-112) instead of 127-112. I hope you understand. The difference between 127 and 112 is the cat's weight, so the cat weighs 15 pounds.
