To use the Associative Property to solve the mathematical sentence 5+35+7, we need to understand that the Associative Property of Addition states that the way in which numbers are grouped does not change their sum. This property can be expressed as:(a+b)+c=a+(b+c).

A. (5 + 35 + 7) = 47

This option presents the sum directly without using the Associative Property explicitly.

It correctly states the sum as 47, but it does not show the grouping.

B. (5 + 35) + 7 = 47

First, we group 5 and 35 together: 5+35=40.

Then, we add 7to the result: 40+7=47.

This option correctly shows the use of th...
