Question

1) simplify by using the associative property of multiplication.

6 (10y) = ___

2) use the commutative and associative properties as needed to simplify the expression
(16 + a) + 15= ___

3) are the expressions in the following pair equivalent?
18x · 0 and 1

Answer 1

1. 6 x 10y = 60y
2. 16 + 15 + a = 31 + a
3. Let’s say x = 2, 18 x 2 x 0 is not equal to 1 because 0 is not 1 so false.
