Graph the solution. k = –26 c<4 Run 2 Run 9 Write the verbal sentence as an equation. Then solve. 7 less than a number n is –6. Solve the inequality. Graph the solution. g ≤ 11 n – 7 = –6 n=1 Run 3 Run 10 Simplify the expression. Solve the inequality. Graph the solution. v ≥ –32 5k + 9 Run 4 Run 11 Simplify the expression. Solve the inequality. Graph the solution. p<8 27a – 42 Run 5 Run 12 Solve the equation. Check your solution. Solve the equation. Check your solution. t=4 h=3 Run 6 Run 13 Solve the equation. Check your solution. Solve the equation. Check your solution. d = –9 k = –54 Run 7 Run 14 Write the verbal sentence as an equation. Then solve. 1 5 A number multiplied by is . 8 56 Solve the equation. Check your solution. 1/8x = –5/56 x = –5/7 x = –26 Pass 1 Write and solve an inequality that represents the value of x. The base is less than the height. x + 7 < 21 x < 14 21 x+ 7 Pass 2 Write an equation. Then solve. The temperature of dry ice is –109.5°F. This is 184.9°F less than the outside temperature. Write and solve an equation to find the outside temperature. t – 184.9 = –109.5 t = 75.4 ºF Pass 3 Write and solve an equation to find the unknown side length. in. 9.2 in. ? 9.2 + 4.2 + 9.2 +x = 26.8 x = 4.2 in 4.2 in. 9.2 in. Pass 4 A dog's water container holds at most 4 cups. There is 2 cups in the container. Write and solve an inequality that shows how much water w your dog has drunk. w+2≤4 w ≤ 2 cups Pass 5 Write an equation. Then solve. It cost $2.00 to rent bowling shoes. Each game costs $4.25. You have $19.00. How many games can you bowl? 4.25g + 2 = 19 g = 4 games Pass 6 Write an equation. Then solve. 1 The price of a bike at store A is the price at store B. The price at store A is $164.84. Write and solve an equation to 2 find how much you save buying the bike at store A? Explain your reasoning. 164.84 = 1/2b b = 329.68 save: $164.84 Pass 7 You are selling daffodils as a fundraiser. A dozen daffodils sell for $12.50. Your goal is to raise $1475. a. Write and solve an inequality to determine how many dozen flowers f you must sell to meet your goal. 12.50f ≥ 1475 f ≥ 118 dozen daffodils b. How does your answer to part (a) change when the price decreases? You must sell more to reach your goal if the price decreases.
