5. Substitution
If x = 5 and y = 7 then 3x + y would equal what?
Remember to place numbers in parentheses when you substitute!
3(5) + 7 = = 22

6. Volume How many cubes are inside the rectangular prism? A) 21 cubes
B) 28 cubes
C) 36 cubes
D) 42 cubes

7. Area Area= 12 cm2 Area= 57.6 m2 6 cm. 4 cm.
12 m
4.8 m
6 cm.
4 cm.
Area= 12 cm2
Area= 57.6 m2

8. Surface Area
What is the surface area of the following shape? Use the formula:
SA = 2(ab) + 2(bc) + 2(ac)
Choose which sides are you’re a, b, and c first.
SA = 324

9. Decimals
The table shows the average baseball ticket price for three American cities.
How much more expensive is it to buy a ticket in New York than in Atlanta?
Location
Average Price
Atlanta
$14.42
New York

10. Operations with Decimals
Dividing: If there is a decimal on the outside of the division sign, you must move it first before you can start dividing.
÷ 6.3
91.4
Multiplying: Multiply like normal and then count the decimal places in your problem and move the decimal to the right in your answer
7.85  3.4
26.69

11. Unit Price If three dozen cookies cost $9, what is the unit cost?
B) $0.50
C) $3.00
D) $4.00
Money goes on the top of your rate and the total number of cookies will go on the bottom. Then you have to divide.

A) octahedron
B) tetrahedron
C) triangular prism
D) triangular pyramid

16. Greatest Common Factor
You can use the ladder method or the rainbow method.
Remember: factors are the numbers you can multiply together to get a larger number (Ex. 1, 2, 3, 6 are the factors of 6)
What is the GCF of 24 and 16? 8

17. Least Common Multiple
List all the multiples of each number until you find the first multiple they have in common
Multiple: think about the multiplication table (Ex. 5: 5, 10, 15, 20…)
What is the LCM of 8 and 10? 40

18. Dividing Fractions ⅞ ÷ ⅖ ⅔ ÷ ½ 1 1/3
Keep, Change, Flip and then just multiply straight across and simplify if necessary
⅞ ÷ ⅖
2 3/16
⅔ ÷ ½
1 1/3

19. x ≥ 9; any number 9 or greater
Inequalities
greater than >, less than <, greater than or equal to ≥, less than or equal to ≤
To solve an inquality, you solve it exactly like an equation (WYDTOSDTTO).
3x ≥ 27
x ≥ 9; any number 9 or greater
To write an inequality from a statement, you must choose the key words and pick which symbol matches the key word
The cost of the shirt will be no more than $10.
s ≤ 10

20. Solving Equations x – 10 = 17 y/8 = 9 4c = 24 x = 27 y = 72 c = 6
Use inverse operations!
What you do to one side, do to the other!
x – 10 = 17
x = 27
y/8 = 9
y = 72
4c = 24
c = 6

21. Converting Fractions, Decimals, and Percentages
Fraction to decimal: Top dog goes in the house (numerator inside the division sign, denominator outside)
Decimal to percent: Move the decimal 2 times to the right
Percent to decimal: Move the decimal 2 times to the left
