A. Inverse Property of Addition
B. Associative Property of Addition
C. Commutative Property of Multiplication
D. Commutative Property of Addition **Weegy:** B. Associative Property of Addition **User:** Bob and his best friend Bill have the same birthday, but Bob is 3 years older than Bill. Let the variable x represent Bob’s age and y represent Bill’s age. Which equation models the relationship between Bill’s age and Bob’s age?
