Which of the following represents the given word problem if "P" represents the population ten years ago? 2(P + 10) = 12,000 2P = 12,000 P = 2(12,000) ?????

6000

what

3. Falling_In_Katt

It says it has doubled over the past ten years. The population now is 12,000. So, you would divide 12,000 by 2 to get the population of 10 years ago.

6000 is not a option tho

5. Astrophysics

Given the information you should be able to figure out the answer now though

6. Falling_In_Katt

whats your options?

7. Astrophysics

If it was 6000 10 years ago, which of the following options would give that?

8. anonymous

there the three things but i know it now its c

9. Astrophysics

No you're looking for the population 10 years ago, and it said it doubled in 10 years to 12000 giving your initial population to be 6000.

oh

11. Astrophysics

Yes, just do the math and it should be clear :)

12. anonymous

so its b because 2 times blank + 12000 and the blank (x) would be 6000

13. Astrophysics

Yes, B is right

14. Falling_In_Katt

correct

15. anonymous

thank you!!

16. Astrophysics

$2P = 12000 \implies P = \frac{ 12000 }{ 2 } = 6000$

i did realy bad job at explaining myself >.<

18. Astrophysics

It's ok :)
