Question

Match these please?
3. 3x+6+1=8
4. 3x+7=8
5. 3x=1
6. x=1/3
A. Subtraction Property of Equality
B. Combine like terms
C. Distributive Property
D. Division Property of Equality

Answer 1

What did you do from step 1 to 2? 6 + 1 = 7. Which choice represents that?

Answer 2

B?

Answer 3

Correct.

Answer 4

That is the only one i understand how to do

Answer 5

From step 4 to 5, you went from 3x + 7 = 8 to 3x = 1.
What happenned to 3x + 7 to become just 3x? What happened to the 7? What happened to 8 to become 1?

Answer 6

Subtract 7 from both sides?

Answer 7

Correct. So now match that to a choice. One is very obvious.

Answer 8

4-b
5-a
6-d
3-c(not sure of this one)

Answer 9

A

Answer 10

@tiffers24 Ignore the above response, and keep working with me one step at a time.

Answer 11

ok

Answer 12

Correct.
The last one:from step 5 to step 6, you went from 3x = 1 to x = 1/3. What happened to 3x to become x and what happened to 1 to become 1/3?

Answer 13

Mmm I'm not sure, divide it?

Answer 14

MAth teachers here brb

Answer 15

Right. You divide 3x by 3 to get x, and you divide 1 by 3 to get 1/3. So the last step was the division property of equality. That is choice D.
The answers are: 4 B, 5 A, 6 D
We can't tell what the answer to 3 is without seeing step 2, to see what happened between step 2 and 3.

Answer 16

3(x+2)+1=8

Answer 17

That was the first one given

Answer 18

Then from that step to 3x + 6 + 1 = 8, the step that was done was going from
3(x + 2) to 3x + 6. That is the distributive property.

Answer 19

Thank you for the help :)

Answer 20

Would you happen to know the answer to this one?
According to the Transitive Property of Equality, if TX = XY and XY = YZ, then TX = ___.
A. TX
B. XY
C. YZ
D. TZ

Answer 21

The transitive property of equality is if a = b and b = c, then a = c.

Look at each equality statement. At first, you don't know anything about a and c. You only know a = b amd b = c, but you can conclude a = c. Now look at your question and try to match it to a, b, and c, and see what you can conclude.

Answer 22

a=b is in this question tx=xy. b=c is xy=yz so tx=yz?

Answer 23

YZ is correct.

Answer 24

Thank you very much
