Inequality Statements

1. Represent each using a set of integers and

symbols.

a) All integers greater than or equal to

zero

______________________________

______________________________

b) All integers less than –10

______________________________

______________________________

c) All integers greater than 5

______________________________

______________________________

d) All integers less than or equal to –3

______________________________

______________________________

2. Use a number line to represent the each

inequality in question 1.

3. Write each symbolic statement in words.

In each question, the variable belongs to

the set of integers.

a) y < 8

______________________________

______________________________

b) m ! 4

______________________________

______________________________

c) x = 7

______________________________

______________________________

d) n > 10

______________________________

______________________________

e) y ! –3

______________________________

______________________________

The Zero Principle

4. Represent each using the zero principle

in three different ways. Draw the tile

models on a separate sheet of paper.

a) 2y

b) –3x

c) –5

5. Which expressions represent zero. Use

tile models to help you. Record your

models on a separate sheet of paper.

a) 3x – 2 – 3x + 4y – 2 – 4y

b) 5 – x + 3y – x – 5 + 2x – 3y

c) –4y + 3y + 3 – y – 3

______________________________

b) 3h – 2 = 16

______________________________

c) 4c – 4 = 24

d) 8m + 1 = 17

______________________________

7. Solve by systematic trial. Show your

calculations for the numbers you tried.

a) 10 = 3r – 17

______________________________

______________________________

b) 22 – 5a = 7

______________________________

______________________________

c) 4h + 10 = 36

Use Algebra Tiles and Algebraic Symbols

to Solve Equations

8. Use algebra tiles to solve these equations.

Show your steps using symbols and by

drawing the tiles on a separate sheet of

paper. Verify your solution.

a) 4x + 2= 10

b) 6y – 3 = 9

c) 2x – 4 =10

d) 5y + 5 = 20

9. Solve, and verify your solution.

a) 3x + 6 = 9

______________________________

______________________________

b) 10x – 5 = 15

______________________________

______________________________

c) 4y – 3 = 9

______________________________

______________________________

d) 2y + 7 = 15
