• Students identify values for the variable in an equation and inequality that result in false number sentences.

**Opening Exercise**

State whether each number sentence is true or false. If the number sentence is false, explain why.

1. 4 + 5 > 9

2. 3 • 6 = 18

3. 32 > 64/4

4. 78 - 15 < 68

5. 22 ≥ 11 + 12

Example 1

Write true or false if the number substituted for g results in a true or false number sentence.

Example 2

State when the following equations/inequalities will be true and when they will be false.

a. r + 15 = 25

b. 6 - b > 0

c. 1/2 f = 15

d. y/3 < 10

e. 7g ≥ 42

f. a - 8 ≤ 15

Exercises

Complete the following problems in pairs. State when the following equations and inequalities will be true and when they will be false.

1. 15c > 45

2. 25 = d - 10

3. 56 ≥ 2e

4. h/5 ≥ 12

5. 45 > h + 29

6. 4a ≤ 16

7. 3x = 24

Identify all equality and inequality signs that can be placed into the blank to make a true number sentence.

8. 15 + 9 ___ 24

9. 8 • 7 ___ 80

10. 15/2 ___ 10

11. 34 ___ 17 • 2

12. 18 ___ 24.5 - 6

**Problem Set**

1. State when the following equations and inequalities will be true and when they will be false.

a. 36 = 9k

b. 67 > f-15

c. v/9 = 3

d. 10+b > 42

e. d-8 ≥ 35

f. 32f < 64

g. 10-h ≤ 7

h. 42+8 ≥ g

i. m/3 = 14
