3 Use substitution to determine which equation below has a solution of n = 10.

4 Which is a solution for x > 5.2 ? a.2 b.3.8 c.6.3 d.0

5 Consider the set of values {6, 7, 9, 12, 15, 24}. Which values from the set makes the inequality y ≤ 9 a true statement? a.6, 7 and 9 b.6 and 7 c.9, 12, 15 and 24 d.12, 15 and 24

6 A school had 425 tickets to the state basketball tournament. There are 105 tickets left. Which equation can be used to find how many tickets have been sold? a.x + 425 = 105 b.105x = 425 c.x – 105 = 425 d.x + 105 = 425

7 Alicia cut 4.25 inches from a piece of ribbon. The piece of ribbon is now 16.5 inches long. Which equation can be used to find the length of the ribbon before it was cut? a.x + 4.25 = 16.5 b.16.5 + x = 4.25 c.x − 4.25 = 16.5 d.16.5 – x = 4.25

8 What real-world problem could be represented by the equation 12x = 132? a.Samantha started with 132 sheets of paper. She printed pictures for her poster and used 12 sheets so far. How many sheets does she have left? b.Each container holds 132 ounces of candy. If there are 12 containers, how much can they hold altogether? c.Andy purchased cans of Mountain Dew for the tournament. If the pop comes in packs of 12 cans each, how many packs of Mountain Dew did Andy purchase if there is a total of 132 cans of pop? d.Linda collected 132 coins for the Pennies for Patients drive. Of these coins, 12 of them were quarters. How many coins were not quarters?

9 a.3 b.40 c.13 d.1.6
