2 x 3 x 3 or 2 x 32
Eric is 13 years younger than Adam. Eric is 7 years old. Write an equation using y to solve how old Adam is.
y - 13 = 7 or y = 13 +7
4n = 24
4n - 6 = 24 - 6
YES! Subtracted 6 from both sides

2.4x = 12
YES! 2.4 x 5 = 12 12 =12!
Are these equivalent?
4(n + 2) and 4n + 4
NO! Distributive Property : 4(n + 2) and 4n + 8 are equivalent
Clare had t seashells. After she bought 8 more seashells, she had 24 seashells. Write an equation to find the number of seashells Clare started with.
t + 8 = 24 or 24 - 8 = t
x + 4 = 13
2(x + 4) = 13/2
NO! One side we multiply by 2, the other we divided by 2
Does Mr. Ciampi watch anime shows?
YES! Exciting for Attack on Titan.....like really excited
x/5 + 9 1/2 = 13 1/2
NO! 5/5 = 1 + 9 1/2 = 10 1/2

15! 5: 5,10,15,20
15: 15, 30, 45
15 shows up in both list first!
There are 30 students in drama club. They are carpooling in 5 vans to preform a play. They want each van to carry an equal number of students. Let s be the number of students in each van. Write an equation to find the number of students in each van?
x/4 + 7 = 31
x/4 + 7 - 5 = 31 - 5
YES! Subtracted by 5 on both sides
What gaming system does Mr. Ciampi play the most?
XBOX or PLAYSTATION
PLAYSTATION (Sony guy for sure).
5 (7- x ) + 4 = 21
NO 5 ( 7 - (5) ) + 4 = 21
5 (2) + 9 = 19 19 is not 21
What is the GCF between 18 and 27
18 : 1,2,3,6,9,18
27: 1,3,9,27
Kendle wants to play several games of laser tag. She has $35 to play s amount of games. Each game of laser tag cost $5. Write an expression using s to figure out how many games she can play.
35 = 5s or
35/5 = s
2x/5 + 7 = 35
3(2x/5 + 7) = 3(35)
YES! Multiplied by both sides by 3
What instrument do I play?
Guitar
(x2 - 20.36) / (1.24 + 3.4) = 1
YES! (x2 - 20.36) = 25 - 20.36 = 4.64
(1.24 + 3.4) = 4.64
4.64 / 4.64 = 1 1 = 1
Write an expression equivalent to
4n2 + 6n + 3 - 2n2 + 3n - 1
2n2 + 9n + 2 Combine like terms!
4n2 - 2n2 = 2n2
6n + 3n = 9n
3 - 1 = 2
Trevor takes up a test at school and completes it in an hour. The test has two sections. If he takes 35 minutes to complete the first section, write an equation using s to represent the second section to solve how long it the second section must take?
(1 hour equals 60 minutes)
60 - 35 = s or
s + 35 = 60
3y - 9 = 29
3y - 9 + n = 29 + n
YES! Adding n to both sides
What college did Mr. Ciampi attend?
