question

Which equation shows the associative property of addition?

u + t = t + u

(t + u) + v = t + (u + v)

t + u = v + w

u + v + w = t

key idea

Associative property:
You can group the addends with parentheses and get the same sum.

solution

(t + u) + v = t + (u + v)

This equation shows the associative property. The grouping of the addends is changed.
