**Section 4-1**Evaluate the expression when m = 5, n = 43, and p = -6. -8**Section 4-1**Evaluate the expression when m = 5, n = 43, and p = -6. 2m + n - p 59**Section 4-1**Write an algebraic expression for the word phrase. twelve less than a number x - 12**Section 4-6**Solve the equation. x = -72**Section 4-6**Solve the equation. -2d + 17 = -39 d = 28**Section 4-6**Solve the equation. 49 = -11 + 5y y = 12**Sections 4-8 & 4-9**Write an inequality to model the situation. The shelf can hold at most 250 pounds. s ≤ 250**Sections 4-3 & 4-4**Write an equation. Then solve. You plan to read 500 pages of a book in one week. You have read 142 pages so far this week. How many more pages must you read? 142 + n = 500 ; n = 358 pages**Section 4-6**Write an equation. Then solve. Ally bought three identical shirts and paid a sales tax of $2.84. What was the cost of each shirt? 3x + 2.84 = 50.18 ; x = $15.78**Section 4-8**Solve and graph the inequality. m – 3 > -24 m > -21**Section 4-9**Solve and graph the inequality. -8p ≥ -56 p ≤ 7**Sections 4-8 & 4-9**Does the inequality flip or stay the same? Do not solve. Explain your reasoning. 4 + w > -10 stays; subtraction does not flip
