  1. Name:_________________________________________________________________________________ Date: _____/_____/__________ Study Guide Unit 4 Test “equations and inequalities” Note: Many problems in this packet will be completed together in class during review time. Students are not expected to complete every single problem in the packet. They should complete several problems from each page-- in addition to studying the notes and past quizzes– in order to be fully prepared for test. TOPICS COVERED ON “equations/ inequalities” TEST: Modeling One -Step Equations (Balance scale with algebra tiles) Solving One and Two-Step Equations Equation Word Problems Solving One-Step Inequalities Graphing One-Step Inequalities NOTES SPACE/HELPFUL TIPS (to be filled out in class):

  2. Modeling equations • Draw tiles onto the below balance scales in order to model the following: • One-Step Equations: • 1. x + -2 = 3 2. 5 + x = -1 • 3. x + (-6) = 2 4. x – 7 = -1 • x – (-3) = 6 6. x – (-2) = -3 • Two-Step Equations: • 7. 2x + 4 = -8 8. 3x + (-1) = 14

  3. One-step equations

  4. two-step equations

  5. equation word problems

  6. solving and graphing inequalities Fill-in-the-Blanks: When multiplying or ______________________________ by a negative number, we __________________________ the inequality sign!!! For the following inequalities, decide whether you would need to switch the direction of the sign. Write “yes” or “no” in the blanks:

  7. multiple choice
