The populations of two towns, town A and town B, are being compared. The population of town A is 4×10↑4 and the population of B is 2×10↑5. How many times greater is the population of town B than town A?

The population of town B is 5 times greater than the population of town A

Step-by-step explanation:

Here in this question, we want to know the number of times in which the population of town B is greater than that of town A

To get the number of times, we simply divide the population of town B by the population of town A

From the question, the population of town B is 2 * 10^5 while the population of town A is 4 * 10^4

So to know the number of times,

We have (2 * 10^5) /(4 * 10^4) = 5

The population of town B is 5 times greater than the population of town A

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
