Write an equation for each problem. Then solve.uoma sitini

1. The headquarters of the United States Department of
Defense is the Pentagon. The Pentagon has 5 sides that
are all the same length. If the perimeter of the Pentagon
is 1,600 m, what is the length of each side?

2. The total weight of Maya and her large cat is 157 pounds.
The cat weighs 19 pounds. How much does Maya weigh?

Answer 1

1. 320 m

2. 138 pounds

Explanation:

To obtain the perimeter of a shape, you just add all of the sides.

So here the pentagon has 5 sides in total and they're the same length. This implies that the perimeter = 5 × Length.

So 5 × Length = 1600 m

Length)= 1600 ÷ 5 = 320 m

2. Total weight here means that Maya's weight plus the cat's weight together is equal to 157. To obtain Maya's weight, we take the total and minus (remove) the cat's weight from it.

Maya's weight = Total - cat's weight = 157 - 19 = 138 pounds
