Question

(13 + 5) + 5 = 23

Choose an equivalent addition sentence that shows the associative property of addition.
A.
(13 + 5) + 5 = 23
B.
23 = (13 + 5) + 5
C.
13 + 5 + 5 = 23
D.
13 + (5 + 5) = 23

Answer 1

D

Explanation:

I'm pretty sure. Hope this helps.

Answer 2

For this case we have that, by definition, the associative property establishes that:

`(a + b) + c = a + (b + c)`

So, if we have:

`(13 + 5) + 5 = 23`

According to the property mentioned above, we have equivalently:

`13+ (5 + 5) = 23`

Answer:

Option D
