Jerald is having drain issues at his home and decides to call a plumber. The plumber charges $35 to come to his house and $60 for every hour they work. If the plumber charges Jerald a total of $305, how many hours did the plumber work? Write and solve an equation to determine the number of hours worked by the plumber. 35x + 60 = 305; x = 7 hours 35x − 60 = 305; x = 10.4 hours 60x + 35 = 305; x = 4.5 hours 60x − 35 = 305; x = 5.7 hours Question 5(Multiple Choice Worth 5 points) (Solving Two-Step Equations MC) Solve the equation for w. w divided by 1.4 minus 3.7 equals 6.5 2 3.92 14.28 7.3 Question 6(Multiple Choice Worth 5 points) (Adding and Subtracting Linear Expressions MC) Which expression is equivalent to the expression quantity negative 6 over 5 times t plus 3 over 16 end quantity minus expression quantity negative 7 over 10 times t plus 9 over 8 end quantity? 13 over 10 times t plus 12 over 16 1 over 10 times t plus 6 over 16 negative 5 over 10 times t plus 21 over 16 negative 5 over 10 times t minus 15 over 16 Question 7(Multiple Choice Worth 5 points) (Solving Two-Step Equations MC) Solve negative a minus eight ninths equals one third for a. a equals 5 over 9 a equals negative 5 over 9 a equals 11 over 9 a equals negative 11 over 9 Question 8(Multiple Choice Worth 5 points) (Adding and Subtracting Linear Expressions MC) Add the expressions. the quantity negative 6 minus one half times p end quantity plus the quantity three fourths times p minus 9 end quantity 4 over 8 times p minus 3 2 over 6 times p plus negative 15 negative 2 over 4 times p plus negative 3 1 over 4 times p minus 15 Question 9(Multiple Choice Worth 5 points) (One-Step Inequalities MC) Which graph represents the solution to the inequality 0.5 is greater than or equal to the product of a number and −0.25? number line with closed circle on 0.5 with arrow shaded right number line with open circle on point on negative 0.5 with arrow shaded left number line with closed circle on negative 2 with arrow shaded
