Answer:

y = -3

Step-by-step explanation:

9y + 9 - 3y + 7 = 2y + 4

Collect like terms;

6y + 16 = 2y + 4

Subtract 2y from both sides;

4y + 16 = 4

Subtract 16 from both sides;

4y = -12

Divide both sides by 4;

y = -3

zhannawk [14.2K]

Given:

Americans who are 65 years of age or older make up 13.2% of the total population.

Required:

The total u.s. population

Explanation:

Let the total population of u.s be x.

According to the given condition.

$13.2\text{ \% of x = 30.3 billion}$

Therefore,

$\begin{gathered} \frac{13.2}{100}\text{ }\times\text{ x = 30.3} \\ x\text{ = }\frac{30.3\text{ }\times\text{ 100}}{13.2} \\ x\text{ = 229.55 billion} \end{gathered}$

Answer:

Thus the total population of u.s is 229.55 billion.
