To use the Associative Property, we can rearrange the terms in the expression \(30m + (21m - 53) + (18 - 2m)\).
Let's analyze the original expression step by step:
1. Start with the expression:
\[
30m + (21m - 53) + (18 - 2m)
\]
2. Rearranging the groups of terms without changing their order (which is applying the Associative Property) gives us:
\[
(30m + 21m) + (18 - 2m - 53)
\]
3. When we check the provided responses, we see that the following expression matches:
\[
(30m + 21m) + (18 - 2m)
\]
Hence, the equivalent expression according to the Associative Property is:
**(30m + 21m) + (18 - 2m)**.
