Assignment # _____ Solving Two-Step Inequalities and REVIEW Standard: AF 4.1 Solve two-step inequalities AF 4.1 Solve two-step equations Name _________________________ Pre-Algebra, Period ______ Date __________________________ Solve a two-step inequality Example: 4y +10 < 18 4y + 10 – 10 < 18 – 10 4y < 8 4y 8 4 4 y<2 Solve a two-step inequality Example: –3x + 10 < 31 –3x + 10 – 10 < 31 – 10 original inequality subtract 10 from both sides simplify divide each side by 4 simplify original inequality subtract 10 from both sides –3x < 21 simplify 3x 21 3 3 divide each side by –3 and reverse the inequality symbol x > –7 simplify Remember: goes with < and > goes with < and > Solve the inequality. Then graph the solution. 1. 4y + 6 < 38 2. –2p + 4 > 14 3. 3n – 6 > 18 4. –2x + 1 < 15 Solve the inequality or equation. 5. 7a + 5 > 40 6. y 8 11 6 7. 6x + 32 = 50 8. 4x – 6 = 42 11. x 5 4 8 9. 9x – 12 = 24 10. –7x – 6 = 8 12. –3x + 5 > –16 13. –5x + 14 = –21 14. What is the solution set to the inequality 7z + 5 > 47? A {z : z < 5} B {z: z > 6} C {z : z < 6} 14. ______ D {z : z > 24} 15. What value of x satisfies the equation 3x + 6 = 24? A 10.0 B 5.0 C 6.0 15. ______ D 7.5 16. A group order 6 meals that cost x dollars each and leaves a $14 tip. The group spends a total of $86. If the equation shows the relationship, how much did each person pay before the tip? 6x + 16 = 88 A $72 B $104 C $16 16. ______ D $12
