Solve the following equation

j - (-5) = 15

• j = 20

• j = 3

• j = 75

• j = 10

Brooklyn is preparing for her younger sister's birthday party. She splits a jar of lollipops evenly among 6 goody bags. The goody bags ends up with 4 lollipops per bag. Which equation can you use to find the number of lollipops n in the jar?

• n/6 = 4

• n - 4 = 6

• 4n = 6

• n + 6 = 4

-8(-8x - 6) = -6x - 22

• 2/5

• -1

• 8/7

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k

-(n - 8) = -2

• 6

• 10

• -10

• -6
