Question

Match each item in Column A to an answer in Column B. Ignore the question mark.

What property is shown by the equation?
1.
(–22 + 17) + 13 = –22 + (17 + 13)

2.
–(27 + (–3)) = –27 + 3

3.
35 + (–15 + 4) = (35 + (–15)) + 4

.
–12 + 6 = 6 + (–12)


Collum B

A.
commutative property

B.
associative property

C.
opposite of a sum property

Answer 1

1. Associative property, because you move parentheses around
2. Opposite of a sum property, because the -'s turn to +'s and the +'s to -'s

...I can't read it anymore o.o all the equations got messed up

Answer 2

3. Is also the associative property, again, moving parentheses

Answer 3

4. Commutative property, because you're switching the order of -12 and 6

Answer 4

Thanks can you answer some more please?

Answer 5

Which is an example of the associative property?

A.
–(18 + 3) = –18 + (–3)

B.
–17 + 0 = –17

C.
(–8 + 10) + 4. = –8 + (10 + 4)

D.
–5 + 7 = 7 + (–5)

Answer 6

Why don't you do them and I'll check your answers?

Answer 7

Yes please.

Answer 8

The Answer is C, i belive.

Answer 9

You're correct :)

Answer 10

Alright, 3 more

Answer 11

–(m + 15) = –18 + (–15)

Answer 12

haha go for it

Answer 13

-18

Answer 14

or 18

Answer 15

Are you trying to figure out what m equals?

Answer 16

Yeah. What value of m makes the statement true?

Answer 17

ohh okay. Well, it doesn't look like they're applying the associative property because there are only 2 sums. And it's not the commutative property either, because the position of the 15 doesn't change. Which leaves which property?
