Question

an ostrich that is 108 inches tall is 20 inches taller then 4 times the height of a kiwi. what is the height of a kiwi in inches?

Answer 1

Height of the kiwi = ? Call it 'K' for now, until we find out what it is.

4 times the height of a kiwi = 4 K

20 inches taller than that = 4 K + 20

You said that's 108 inches, so we can write

4 K + 20 = 108

Subtract 20 from each side: 4 K = 88

Divide each side by 4 : K = 22 inches .
