If this occurred over a span of 35 years and the population doubles every 7 years, we can divide 35 by 7 to find how many times the population has doubled, which would be 5 times. If we divide 60,000 by 2 (or multiply by 1/2) 5 times, you would get the answer, which would be 1,875.

I am thinking of a number.
mash [69]

Answer:

21

Step-by-step explanation:

Let x be that number.

12x-216=2x-6

12x-2x=-6+216

10x=210

10x/10=210/10

x=21

21 is the number.
