Lesson 4 Homework PracticeProperties of Numbers

Name the property shown by each statement.

1. 55 + 6 = 6 + 55 Commutative Property of Addition

2. 6 � 7 = 7 � 6 Commutative Property of Multiplication

3. (x + 3) + y = x + (3 + y) Associative Property of Addition

4. 1 � mp = mp Multiplicative Identity

5. 9 + (5 + 35) = (9 + 5) + 35 Associative Property of Addition

6. 67 + 0 = 67 Additive Identity

7. 7x � 0 = 0 Multiplicative Property of Zero

8. 4(3 � z) = (4 � 3)z Associative Property of Multiplication

Simplify each expression.

9. a(5 � 7) 35a 10. (24 + s) + 16 s + 40

11. c + (17 + 8) c + 25 12. 72g(1) 72g

13. 31 + (21 + p) p + 52 14. (e � 4) � 12 48e

15. (m + 11) + 19 m + 30 16. (9 � b ) � 10 90b

17. 19 + (v + 8) 27 + v 18. (28 + 12) + x 40 + x

19. 8s � 0 0 20. 4 � (r � 5) 20r

21. The volume of a box is given by V = ℓ � w � h where ℓ = length, w = width, and h = height. Find the volume of a box if the length is 25 cm, width is 13 cm, and height is 4 cm. V = 25 cm � 13 cm � 4 cm = 25 cm � 4 cm � 13 cm = 1300 cm3

22. In math class each assignment is worth 20 points. David got 17, 20, 19, and 13 points on his last four assignments. How many points did David score all together? 17 + 20 + 19 + 13 = 17 + 13 + 20 + 19 = 69 points

23. State whether the following statement is true or false: Multiplying any number by one produces the original number. Explain. True; sample answer: The Multiplicative Identity states that any number times one is the original number.
