The constant of variation is k=5

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

Where k is the constant of proportionality.

We know R varies directly with S. Their relationship is:

We also have when S=16, R=80. Thus:

Solving for k:

The constant of variation is k=5

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
