Study the steps used to solve the equation. Given: Step 1:c/2 - 5=7 Step 2:c/2 - 5+5=7+5 Step 3:c/2 + 0 = 12 Step 4:2(c/2 ) = 12(2) Step 5:c=24 Choose the property that justifies each step of the solution. Step 1: addition property of equality Step 2: additive inverses Step 3: additive identity Step 4: multiplication property of equality What is the solution set of -|-x| = -12? {-12, 12} It takes Mr. Martin 12 minutes to drive his bus route without stopping to pick up any passengers. For each passenger stop, he estimates that 30 seconds is added to his travel time. On Tuesday, Mr. Martin spends 14 minutes driving his route. Which equation can be used to determine the number of passenger stops, p, Mr. Martin had on Tuesday? 14 = 0.5p + 12
