In 2009, the us had a population of about 307 million people. if there were 14 births and 8 deaths per 1000 people, what was the country's net population growth that year (ignoring immigration and emigration)?

1,842,000 of net population growth

Explanation:

Since we have 14 births and 8 deaths per 1,000 people, it means that on every 1,000 people we have 6 people more for that year. Considering that the population is 307 million, we need to see how much 1,000's there are in 307 million:

307,000,000 / 1,000 = 307,000

In order to get the total net population growth we need to multiply 307,000 with the growth on every 1,000 people:

307,000 x 6 = 1,842,000

So we get a net population growth of 1,842,000 for that year.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
