Solve for each variable. Be sure to go through the steps of Don't Call Me After Midnight. 1. 12(x - 20) = -48x=16 2. 0.25(3 + a) = 0.5a = -1 3. -3a=15a=-5 4. b = -7b=21 5. 12=0.3nn=40 6. 2 = 8 4 7. 4x + 6 = 10x=1 Solve each inequality 8. x -3 > 9x>12 9. -5m > 20m<4 Write an inequality for each scenario 10. five more than a number is more than elevenx+5>11 Solve each equation. 11. -3y – 7 = 2y=-3 12. x - 3 = -5x=-14 13. x + 2 = -11 as an improper fraction x=-25 14. 5n + 16 + 4n = 133n=13 Write an EQUATION then solve the equation. Be sure to read the question carefully and look for key words. 15. Emma has $145 in her savings account. She earns $36 a week mowing lawns. Write and solve an equation to find out how many weeks it will take Emma to save $433.write your equation (don't use spaces) 36w+145=433It will take Emma 8 weeks to save $433. 16.
