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 [tex]12 - 7 + 3[/tex]?
Solution :
Associative property states that, [tex]a+(b+c)=(a+b)+c[/tex]
Commutative property states that, [tex]a+b=b+a[/tex]
By definition of properties we conclude that option 4 applies the correct property i.e. commutative.
As [tex]12 - 7 + 3=12+3+(-7)[/tex]
[tex]5 + 3=15-7[/tex]
[tex]8=8[/tex]
Therefore, The expression is equivalent to [tex]12 + 3 + (-7)[/tex] because of the commutative property.
So, Option 4 is correct.
