Question

Which of these shows 7 + 2y rewritten using the commutative property of addition?

7y + 2

2y + 7

7 − 2y

2y − 7

Answer 1

the `commutative property of addition` is a fancy way of saying "you can add 2 numbers in any order"

examples:
1+2 = 3
2+1 = 3


7+8 = 15
8+7 = 15


29+11 = 40
11+29 = 40


and so on...

Answer 2

This applies to algebra because variables are just placeholders for numbers, so something like x+y is the same as y+x

Answer 3

B!

Answer 4

correct
