516 <strong>Chapter</strong> 9 Solving Equations and Inequalities Getting Ready for Class After reading through the preceding section, respond in your own words and in complete sentences. 1. What is the distributive property? 2. What property allows 5(x 1 3) to be rewritten as 5x 1 5(3)? 3. What property allows 3x 1 4x to be rewritten as 7x? 4. True or false? The expression 3x means 3 multiplied by x.
9.1 Problem Set 517 Problem Set 9.1 A For review, use the distributive property to combine each of the following pairs of similar terms. [Examples 1–3] 1. 2x 1 8x 2. 3x 1 7x 3. 24y 1 5y 4. 23y 1 10y 5. 4a 2 a 6. 9a 2 a 7. 8(x 1 2) 8. 8(x 2 2) 9. 2(3a 1 7) 10. 5(3a 1 2) 11. 1 } 3 (3x 1 6) 12. 1 } 2 (2x 1 4) B Simplify the following expressions by combining similar terms. In some cases the order of the terms must be rearranged first by using the commutative property. [Examples 4–6] 13. 4x 1 2x 1 3 1 8 14. 7x 1 5x 1 2 1 9 15. 7x 2 5x 1 6 2 4 16. 10x 2 7x 1 9 2 6 17. 22a 1 a 1 7 1 5 18. 28a 1 3a 1 12 1 1 19. 6y 2 2y 2 5 1 1 20. 4y 2 3y 2 7 1 2 21. 4x 1 2x 2 8x 1 4 22. 6x 1 5x 2 12x 1 6 23. 9x 2 x 2 5 2 1 24. 2x 2 x 2 3 2 8 25. 2a 1 4 1 3a 1 5 26. 9a 1 1 1 2a 1 6 27. 3x 1 2 2 4x 1 1 28. 7x 1 5 2 2x 1 6 29. 12y 1 3 1 5y 30. 8y 1 1 1 6y 31. 4a 2 3 2 5a 1 2a 32. 6a 2 4 2 2a 1 6a
