Final answer:
The equivalent expression to -5d + -1/2 using the Commutative Property of addition is -1/2 + -5d, represented by option C).
Step-by-step explanation:
The question asks which expression is equivalent to -5d + -1/2 using the Commutative Property.
In Mathematics, the Commutative Property states that the order in which two numbers are added or multiplied does not change the result
Applying this property to the given expression, we simply rearrange the terms without altering the overall value. Therefore, the equivalent expression is -1/2 + -5d, which is represented by option C).
