What property is shown? –12 + (27 + 12) = –12 + (12 + 27)

A.associative property
B.commutative property
C.distributive property
D.opposite of a sum property

Answers

Answer 1
Answer: commutative property is
a+b=b+a
we see the only difference between -12+(27+12) and -12+(12+27) is they are switched

so it would be commutative
it's not associatve because associative deals with moving parenthasees
Answer 2
Answer: Correct option B commutative property
The numbers are just switched, there is no difference in it.
a + b is same as b+a
Similarly,
-12 + 27+12 = -12 + 39 = 27
-12+12+27 = 27
See, no change takes place,just the positions of the numbers are changed

he is wrong, its 30. not 300 thousandths
He is incorrect because .3 ( three tenths ) x 100 = 30, not 300, because .3 is a decimal. If it was 3 x 100, he would have been correct. BRYARTOWNSEND is correct.

Brain was asked to round 4.44 to the nearest tenth and said it was 4.5 Is he correct?Why or Why not?

Answers

Brian (I think you meant Brian haha..) is incorrect because the tenth place is the number right after the decimal which is a 4. If you are rounding to the tenth place that means that you have to look at the number to the right of that, which is 4. 5 and up means you round up and 4 and down means you round down. This is a 4, so you keep the 4 after the decimal and get rid of the last 4. Therefore, when rounded it would be: 4.4.
Hope this helped! Good luck! :)
The answer is 4.4 hope i helped :)
