You then would eliminate 6, by adding 6 to both sides
Then you want all of the X's on the same side, so you subtract 2x from both sides.
Then to isolate the X, you divide by 2
The answer is x=2
You can figure the remaining percentage in 2050 and calculate using that, or you can figure the amount of population that will be lost and subtract that from the 2006 value.
<u>First method</u>: The remaining population will be 100% - 5.8% = 94.2% of that in 2006. 0.942×40.2 million ≈ 37.9 million
<u>Second method</u>: 5.8% of 40.2 million is about 2.3 million, so the remaining population will be 40.2 - 2.3 = 37.9 million
I hope this helps you
10 1/2 + 10 + 7 + 6 + 3 1/2 +4
10+1/2+27+3+1/2
40+1/2+1/2
40+2/2
40+1
41
Increased slowly, increased quickly
