Question

Which statement shows the associative property of addition? 3⋅(5⋅x)=(3⋅5)⋅x 21 + 2y = 2y + 21 (u + 7) + 13 = u + (7 + 13) If m + 3 = 18, then 18 = m + 3.

Answer 1

(u + 7) + 13 = u + (7 + 13)

Step-by-step explanation:

The associative property moves the parenthesis.  We are doing addition , so we need to look for the problem that moves the parenthesis on addition.
