Translating this sentence into symbols:  2(x+3) = x - 5

So 2x + 6 = x - 5                    and x = -11

Check:  Is 2(-11+3) = -11 -5?               Is -16 = -16?  YES.  x =-11 is right.

The land area of a country is about 5.0 million square​ miles, and the population is about 600 million people. What is the avera
podryga [215]

Answer:

120 people/sq. mile

Step-by-step explanation:

Population Density is the concept of how "crowdy" a place is. The more the population density, the more crowded that place is.

The population density is found by dividing the "number of people" by the "land area" (in sq mile or sq km).

Here, it is given there are 600 million people, so

Number of People = 600,000,000

And, the land area is given as 5 million square miles, so

Land Area = 5,000,000 sq. miles

Hence,

Population Density = 600,000,000/5,000,000 = 120 people/sq. mile

No your friend I’d not correct although the slope is 4, the y-intercept is -3 because of the minus 3 in the equation.
