Every polynomial with rational coefficients has the same roots as one with integer coefficients; just multiply through by the common denominator. The complex roots of such polynomials come as conjugate pairs.
Multiply the rate per mile by the miles and the appropriate conversion factor.

The car leaked 2.25 cups of oil on the trip to grandma's house.
7.14/6 = 1.19 per granola bar
8.72 / 8 = 1.09 per water bottle
7 granola bars + 9 bottles of water =
7(1.19) + 9(1.09) =
8.33 + 9.81 =
18.14 <===
1. This is one confusing question... But here is what I did
x = 2y + 1
y =

+ 2x
So plug in Y to solve for X
x = 2 (

+ 2x) + 1
x =
- 
Not sure if that's completely correct, but I'm positive I didn't make any mistakes...
5. You have to find the multiples of 60 so...
1 60
2 30
3 20
4 15
<span>5 12
<---
7 = 12 - 5</span>
Answer: THE ANSWER IS 2,800
