Combine like terms
-7y² + 6y² - 2y² = -3y²
4y + (-5y) - (-9y) = 4y - 5y + 9y = 8y
9 + 9 - (-2) = 9 + 9 + 2 = 20
-3y² + 8y + 20 is your answer

A convenience sample is made up of people who are easy to reach so it would be B
Answer: 2 packages
Step-by-step explanation:
If mark bought 1 for $4 then shreds can buy 2 for $8
First let’s add the whole numbers.
8 + 7 + 6 = 21
Now let’s add the fractions.
1/2 + 1/4 = 3/4 or 0.75
Finally let’s add the whole numbers to the factions.
21 + 3/4 = 21 3/4
Or you can do 0.75
21 + 0.75 = 21.75
So your answer is either 21 3/4 or 21.75
Hope that helps :)
