2.25 + 8.50x = 50
8.50x = 50 - 2.25
8.50x = 47.75

8.50. 8.50
x = 5.6 hours
Hope that helps :)
So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
We can withdraw a equation to give mexico population
P = M.(1 + i)^t
So,
First of all, how many years passed? 2015 - 2000 = 15. Our time is 15, our annual rate is 1,7%, time to calc.
P = 100350000.(1 + 1,7%)^15
1,7% = 0,017
P = 100350000.(1 + 0,017)^15
P = 100350000.(1,017)^15
P = 100350000.1,2876988084901218382866596204289
P = 129220575,43198372647206629291004
Rounding
P = 129,220,575

Well if you want to turn an improper fraction to a mixed number you just divide the denominator by the numerator if that's what your asking
