Dividing by a fraction is the same as multiplying the reciprocal of the fraction. What is the reciprocal of a fraction? It's essentially the same fraction, just the numerator and denominator switching places (flipping the fraction upside down). Knowing this, the following is true:
We also need to know that whenever the denominator of a fraction is 1, the fraction is equal to the numerator itself. Knowing this, the following is also true:
Applying this to the first concept, we can say that:

Answer:
We have a problem here, Houston.
Step-by-step explanation:
Is "(x+5)2=36" supposed to be (x+5)<u>^</u>2=36 ?
If so,
x = ± 11
-----------------------
If it is indeed (x+5)2=36
then:
2x + 10 = 36
2x = 26
x = 13

We conclude that she needs to route 10 phone calls to spend a total of 20 minutes in the phone (assuming that the unit rate does not change).

How many phone calls does Aaliyah have to route to spend a total of 20 minutes on the phone?</h3>
First, we know that she spends 10 minutes on the phone while routing 5 phone calls.
Then the unit rate is:
(5 phone calls)/(10 min) = 0.5 phone calls per min.
Now, if she spends 20 minutes, the number of phone calls that she will route (assuming that the unit rate does not change) is:
N = (0.5 phone calls per min)*20 min = 10 phone calls.
We conclude that she needs to route 10 phone calls to spend a total of 20 minutes in the phone (assuming that the unit rate does not change).
