Answer:

250 people per mile.

Step-by-step explanation:

We need to find the population density. To calculate the population density we need to divide the number of people in the place by the area of the place, that is

puplation density = number of residents / area of the territory. Then,

population density = \frac{3000 people}{12miles^2}=250people/miles.

Then, the density is 250 people per mile.

inna [77]
First you distribute what’s outside the parentheses (the -4)

-4•4= -4y
-4•-2= 8

New equation: -4y+8=12

Now you solve like a normal equation
12-8 is 4

New equation: -4y=4

Now divide

now, if that value is less than 100, then the fellow is "undernourished", otherwise, is overfed.

Question 9 (1 point)
vitfil [10]

Answer:

Option 3: 200L + 100B > 5,000

Step-by-step explanation:

Each laptop costs 200 dollars, so this could be represented as 200L. Each bike costs 100 dollars, so this could be represented as 100B.

Jonathan wants his total of laptops and bikes to be more that 5,000, so we have to add 200L and 100B. When added, it should be more than 5,000 dollars.

200L + 100B > 5,000
