Chapter 3 Get Ready
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

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
