Question

Indicate which property is illustrated in Step 2.

Step 1 7 - 8x - 7 + 9x = (7 - 8x) + (-7 + 9x)
Step 2 = (7 - 8x) + (9x - 7)
Step 3 = 7 + (-8x + 9x) - 7
Step 4 = 7 + (-8 + 9)x - 7
Step 5 = 7 + x - 7
Step 6 = x + 7 - 7
Step 7 = x + 0
Step 8 = x

Answer 1

What did you put?

Answer 2

associative

Answer 3

(7 - 8x) + (-7 + 9x) to (7 - 8x) + (9x - 7)

Answer 4

(7 - 8x) + (-7 + 9x) to (7 - 8x) + (9x - 7)

Answer 5

This (-7 + 9x) to (9x - 7)

The order has changed. Which property? NOT associative.

Answer 6

starts with a d

Answer 7

starts with a c

Answer 9

Indicate which property is illustrated in Step 1.

Step 1 7x + 11 + 2x + 4 = (7x + 11) + (2x + 4)
Step 2 = 7x + (11 + 2x) + 4
Step 3 = 7x + (2x + 11) + 4
Step 4 = (7x + 2x) + (11 + 4)
Step 5 = (7 + 2)x + (11 + 4)
Step 6 = 9x + 15

Answer 10

It is the grouping property again.

Answer 11

associative

Answer 12

Correct

Answer 13

Indicate which property is illustrated in Step 3.

Step 1 3x + 11 + 9x + 9 = (3x + 11) + (9x + 9)
Step 2 = 3x + (11 + 9x) + 9
Step 3 = 3x + (9x + 11) + 9
Step 4 = (3x + 9x) + (11 + 9)
Step 5 = (3 + 9)x + (11 + 9)
Step 6 = 12x + 20

Answer 14

@Starr_Dynasty What did you get?

Answer 15

2nd

Answer 16

(11 + 9x) to (9x + 11) NOT Associative

Ordering Property

Answer 17

See chart to review.

Answer 18

Indicate which property is illustrated in Step 4.

Step 1 9 - 8x - 9 + 9x = (9 - 8x) + (-9 + 9x)
Step 2 = (9 - 8x) + (9x - 9)
Step 3 = 9 + (-8x + 9x) - 9
Step 4 = 9 + (-8 + 9)x - 9
Step 5 = 9 + x - 9
Step 6 = x + 9 - 9
Step 7 = x + 0
Step 8 = x

Answer 20

After this problem, start a new thread, please.

Answer 21

9 + (-8x + 9x) - 9 to 9 + (-8 + 9)x - 9

Answer 22

This is what has changed:

(-8x + 9x) to (-8 + 9)x


That's our friend with a "D."
