Answer 1

Because the emperor penguin is 24 inches taller than the rockhopper, we use the equation 45 - 24 = r. (r is a variable for rockhopper penguin.)

Solve 42 - 24 = r
18 = r therefore, the height of the rockhopper is 18 inches.

We can check our answers. 24 + 18 is the height if the emperor, which is 45 inches.
