1. 2.3-2.5 Review

2. Determine which property is being used: • If 2x = 8 then x = 4 • If and then • If ST = RQ then RQ = ST

3. Solve the following equation and justify each step. 3(2x + 7) = 27

4. Use the Law of Detachment to draw a conclusion if possible. • If a student is on the basketball team, then the student has passing grades. Theresa is on the basketball team. • If you miss the bus then you will be late for school. You are late for school.

6. Use the given property to complete each statement: • Multiplication Property of Equality If x + 4 = 12 then 2(x + 4) = __________ • Reflexive Property of Congruence ___________ • Symmetric Property of Congruence If then _____________

7. Find the values of x and y 2x + 15y - 7 4y + 6 6x + 12

8. Use the Law of Syllogism to make a conclusion if possible: I feel better when I take Tums. Chalupas give me stomach aches. I get Chalupas when I go to Taco Bell.I don’t take Tums when I don’t get a stomach ache.

9. Given: are complements are complements Prove: C B D M E A

10. Given and are congruent supplements and supplementary to which has a measure of 122˚, determine the measure of Given is complementary to 30˚ and is a congruent complement to , find the
