The expression is equivalent to 12 + 3 + (-7) because of the associative property. The expression is equivalent to 12 - 3 + 7 because of the commutative property. The expression is equivalent to 12 + 3 + (-7) because of the commutative property.

Answer 1

Answer:

Option 4 - The expression is equivalent to 12 + 3 + (-7) because of the commutative property.

Step-by-step explanation:

To find : Which statement is true about the expression $12 - 7 + 3$?

Solution :

Associative property states that, $a+(b+c)=(a+b)+c$

Commutative property states that, $a+b=b+a$

By definition of properties we conclude that option 4 applies the correct property i.e. commutative.

As $12 - 7 + 3=12+3+(-7)$

$5 + 3=15-7$

$8=8$

Therefore, The expression is equivalent to $12 + 3 + (-7)$ because of the commutative property.

So, Option 4 is correct.
