Solve: x + 5 = 12
x = 7
Write the ratio of 3 apples to 5 oranges.
3:5
What are the names of the values at the ends of a box plot?
Minimum and maximum
Simplify: 4(3 + 5)
4 × 3 + 4 × 5 = 12 + 20 = 32
Solve: 3 + 4 × 2
3 + 8 = 11
Solve: x - 4 = 9
x = 13
Simplify the ratio 6:9
2:3
Find the median of this data set: 4, 6, 8, 9, 10
8
Use the distributive property to simplify: 5(x + 2)
5x + 10
Solve: (5 + 3)^2 - 4
8^2 - 4 = 64 - 4 = 60
Solve: 6x = 36
x = 6
If the ratio of boys to girls is 4:6, what fraction are girls?
6/(4+6) = 6/10 = 3/5
What is the interquartile range (IQR) of this data: 3, 5, 7, 8, 10, 12, 14
Q1 = 5, Q3 = 12, IQR = 12 - 5 = 7
Use the distributive property to simplify: 6(2x - 3)
12x - 18
Solve: 18 ÷ (3 × 2) + 4
18 ÷ 6 + 4 = 3 + 4 = 7
x ÷ 3 = 7
x = 21
What is the missing value: 2/3 = ?/12
8
Draw and label a box plot for the data set: 2, 4, 5, 7, 8, 9, 10, 13, 14
Min = 2, Q1 = 5, Median = 8, Q3 = 10, Max = 14
Factor: 12x + 18
6(2x + 3)
Solve: [(6 + 2) × 3]^2
(8 × 3)^2 = 24^2 = 576
2x - 4 = 10
x = 7
