Pretty sure it's a trick question, and you can't
If it gained 4 million people every 6 years, then the gain PER year would be 1.5 million. from 1992 to 2012 is 10 years. So, 1.5 times 10 is 15. 72 + 15 =87.
Your answer is 87 million.
Answer:
A. No, because not all of the pairs represent the same ratio
Lets start with the chain of 3's:
18 = 3 + 3 + 3 + 3 + 3 + 3
But, we know that
3 + 3 = 2 + 2 + 2
Sol, let's replace 3 + 3 by 2 + 2 + 2 one by one.
Hence, the possible ways of combinations are listed below:
18 = 3 + 3 + 3 + 3 + 2 + 2 + 2 (1)
18 = 3 + 3 + 2 + 2 + 2 + 2 + 2 + 2 (2)
Therefore, there are two combinations of 2- and 3- point shots that could total 18 points.
