The Pappas family has two cats, Zeus and Athena. Together they weigh thirteen pounds. Zeus weighs 5 pounds less than Athena. How much does Athena weigh?

Given:

Combine weight of two cats, Zeus and Athena = 13 pounds

Zeus weighs 5 pounds less than Athena.

To find:

The weight of Athena.

Solution:

Let x pounds be the weight of Athena.

Zeus weighs 5 pounds less than Athena.

Weight of Zeus = x - 5 pounds

Combine weight of two cats, Zeus and Athena = 13 pounds

Add 5 on both sides.

Divide both sides by 2.

Therefore, the weight of Athena is 9 pounds.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
