Translate: Eight less than a number is at least 9

3
Translate: Eight less than a number is at least 9 n – 8 > 9

4
Translate: Five more than a number is at most 44

5
Translate: Five more than a number is at most 44 n + 5 < 44

6
Translate: After depositing $30, Amy had more than $300 in her savings account.

7
Translate: After depositing $30, Amy had more than $300 in her savings account. x + 30 > 300

Word Problem: Peachey designs planners for $10 a planner. Write and solve an inequality for the number of planners she must design to earn at least $144.

13
Word Problem: Peachey designs planners for $10 a planner. Write and solve an inequality for the number of planners she must design to earn at least $144. X = number of planners designed 10 x > 144 X > Peachey must design at least planners.

Solve and Graph: -15 > t – 4

15
**Solve and Graph: -15 > t – 4 + 4 + 4 -11 > t t< -11**

-11 > t t< -11

16
Solve and Graph: 8p < - 40

17
Solve and Graph: 8p < - 40 p < -5

18
Solve and Graph: x + 8 > 4x

19
**Solve and Graph: x + 8 > 4x - x - x 8 > 4 x 4 4 2 > x**

2 > x X < 2

20
Solve and Graph: - 4z + 10 < z

21
**Solve and Graph: 4z + 10 < -27 + z + 4z + 4z 10 < -27 + 5z**

37 < 5z 7.4 < z Z > 7.4

22
Solve and Graph: 4(2 – x) > 18

23
**Solve and Graph: 4(2 – x) > 18 8 – 4x > 18 - 8 -8 - 4x > 10**

- 4x > 10 x < -2.5

24
Solve and Graph: c 2 + 5 > 8

25
**Solve and Graph: c 2 + 5 > 8 - 5 -5 (2) c 2 > 3 ( 2) c > 6**

(2) c 2 > 3 ( 2) c > 6
