1. State the property illustrated by each
statement.
1•a=a
7(x + 3y) = 7x + 21y

2. Simplify:
9 [ 16 - 2 ( 3 + 2 ) ]

3. Evaluate:
6a2 + b( c – a)
if a = 2, b = 6, and c = 5

4. Write the equation and then solve:
15 less than a number is fifty two.
Find the number.

5. Simplify.
2( 3a + 6b ) + 3( a + 12)

6. Compare the two expressions:
3•2 +5 and 3 ( 2 + 5)
Are these two expressions equivalent?
Explain your reasoning, you must show
work to defend your opinion.

7. Solve. You must show work.
3n = 27 x - 13 = 24

8. State whether the following inequality is true
or false for the given value:
5n + 3 > 26 , n = 5

9. Translate into an inequality:
Mark scored at least 21 points playing
football.

10. Evaluate if:
a=3 b=7 and c=4
5c – 3b – a + 16 ______ 0
Then write <, >, or = on the _____ to make
a true sentence.
