I believe it would be 6^3
The answer is x=2
Remember, first add/substract the like terms, in this case 6x-10x to get -4x. Then, add 8x to negative 8x to cancel it out and do the same thing to -4x. Do this with all your terms and you should get 4x=8. Then divide both sides by 4 to get x=2.
4420 people in 1993
5600 people in 1998
(5600 - 4420) = 1180....so they gained 1180 people in 5 years (from 1993 to 1998)
1180/5 = 236.....thats 236 people per year.
So in 2000.....which is 2 years from 1998, at 236 per yr =
5600 + 2(236) = 5600 + 472 = 6072 (population in 2000)
Set up a ratio with the known dimensions:
24/15 = 40/x
Cross multiply:
24x = 600
Divide both sides by 24:
X = 25
