1000 miles per month.
12 months in a year.
1000 × 12 = 12000 miles per year
Oil change every 4000 miles.
12000 ÷ 4000 = 3
Therefore 3 oil changes per year.
1(x-1)/2-1(3-X)/4=2/1. X-1/2-3+x/4=2/1. Find common denominator. 2x-2-3+x=8. 2x+x-5=8 3x=8+5. X=13/3.
<span>50x - 32x^3
= 2x (25 - 16x^2)
hope that helps</span>
What I would do for this problem, is move all the terms that don't contain m to the right side, and then solve.
m = 4/5.
