Step-by-step explanation:

3n + 9 (2n - 5) = -3n

3n + 18n - 45 = -3

Papessa [141]

Answer:

317,988,000

Step-by-step explanation:    

We have been given that according to the United States Census Bureau, on September 11, 2014, the population of the United States was increasing by 11 people every 12 seconds.

Let us find number of people increased in 1 minute as:

11\times \frac{60}{12}=11\times 5 =55

Now, we will convert 11 years into minutes and multiply by 55 to find increase in population in 11 years.    

\text{11 years}=11\text{ years}\times \frac{365\text{ days}}{\text{year}}\times \frac{24\text{ hours}}{\text{days}}\times \frac{60\text{ min}}{\text{hour}}

\text{11 years}=11\times 365\times 24\times 60\text{ min}

\text{11 years}=5,781,600\text{ min}

Upon multiplying 5,781,600 by 55, we will get:

\text{Population increase in 11 years}=5,781,600\text{ min}\times \frac{55 \text{ people}}{\text{min}}

\text{Population increase in 11 years}=5,781,600\times 55 \text{ people}

\text{Population increase in 11 years}=317,988,000 \text{ people}

Therefore, the population of United States would increase 317,988,000 in 11 years.
