Thank You.
You are welcome. Do not forget that site. It explains lots of stuff.
To determine which property is illustrated by the equation 4 + x + 7 = 4 + 7 + x, let's analyze the equation step by step.
Step 1: 4 + x + 7 is the left side of the equation, and 4 + 7 + x is the right side.
Step 2: When we rearrange the terms on the right side, we get 7 + 4 + x.
Step 3: By the commutative property of addition, we can rearrange the terms without changing the overall value of the expression.
Step 4: Therefore, the equation shows the commutative property of addition, which allows us to rearrange the order of the addends without changing the sum.
Hence, the correct answer is C. Commutative property of addition.
