Alex swims 20 minutes per day for exercise. The total number of minutes, m, she swims equal 20 times the number of days, d, she swims. What the dependent variable?

The total number of minutes, m.

Step-by-step explanation:

The dependent variable is the variable in which the variable cannot stand by itself.

In this situation, the total number of minutes, m, equal 20 times the number of d.

m = 20d

d, is a variable which can be multiplied which states that it has a value, no matter what. On the other hand, m, requires d, to be there in order to have a value.

The answer is, m, the total number of minutes.
