A prize wheel at a carnival has eight spaces, and is equally likely to land on any of them. Four of the spaces give out a sticker, two of the spaces give out a pair of sunglasses, one of the spaces gives out a gift card, and one of the spaces gives out a water bottle. What is the probability of winning a pair of sunglasses on the first spin and a gift card on the second spin?

The difference of the polynomials given is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵
Given are two polynomials are :
(-2x³y² + 4x²y3³ - 3xy⁴) and (6x⁴y - 5x²y³ - y⁵)
We need to subtract the polynomials and find the difference.
(-2x³y² + 4x²y3³ - 3xy⁴) - (6x⁴y - 5x²y³ - y⁵)
By multiplying the signs into the brackets
= -2x³y² + 4x²y3³ - 3xy⁴ - 6x⁴y + 5x²y³ + y⁵
Grouping the like terms, we get
= -2x³y² + (4x²y3³ + 5x²y³) - 3xy⁴ - 6x⁴y + y⁵
= -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵
Therefore, the difference between the polynomials is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

First we need to get common fractions. The way we do this is: is there anyway to make a 2, a four? Yes! There is! (If there is not, you have to find the Least common multiple)
How do we make this two a four? we times it by 2! But we have to be nice, and multiply the whole fraction, just to be fair.
So, we now have 4 3/4 rope, and James wants to get rid of 1 2/4 rope.
For starters, lets go easy. He has 4 foot, he wants one gone. So he has 3 feet of rope left.
But we still have the fractions! He has 3/4 rope, and we want to get rip of 2/4! so we subtract the numerators, and are left with 1/4 (its important you remember to keep the denominator in this case!)
So if we combine that, James will be left with 3 1/4 feet of rope!

Step-by-step explanation:
We have been given that Garland started the week with an odometer reading of 58,240 miles and a full tank. He ended the week with an odometer reading of 58,615, and he re-filled the tank with 15 gallons of gas.
To find the mileage for Garland's bike we will divide total distance traveled by total used fuel.
Therefore, Garland get a mileage of 25 miles per gallon and option A is the correct choice.

1 kilogram of cinnamon red hots ... x = ?
3 kilograms of cinnamon red hots ... 3 * x = ?
1 kilogram of gummy bears ... y = ?
3 kilograms of gummy bears ... 3 * y = ?
Erika: 3 * x + y = $21.00
Irene: 3 * x + 3 * y = $39.00
3 * x + y = 21
3 * x + 3 * y = 39
_________________
3 * x + y - (3 * x + 3 * y) = 21 - 39
3 * x + y - 3 * x - 3 * y = - 18
- 2 * y = - 18 /(-2)
y = $9
3 * x + y = $21.00
3 * x = 21 - y
3 * x = 21 - 9
3 * x = 12 /3
x = $4
The correct result would be: 1 kilogram of cinnamon red hots cost $4 and 1 kilogram of gummy bears cost $9.
