Please check this. I'd appreciate it.
What is the value of x? Justify each step?
They want me to name the properties that each step belongs to. (i.e. transitive, symmetric, division property of equality, etc.)
AC = 32
I'll draw it in the comments.
AB + BC = AC a. Transitive Property
2x + 6x + 8 = 32 b. Addition Property of Equality
8x + 8 = 32 c. Subtraction Property of Equality
8x = 24 d. Division Property
x = 3 e. Substitution

I know that the steps are correct. However, they wanted me to name the properties that each step belongs to. (i.e. transitive, symmetric, division property of equality, etc.) I know that there are nine properties in total. I just wanted to make sure that I had them with the correct steps.

My main question is if they want the x = 3 step to account for the substitution property of equality or do they want me to write 'proven.'

For x=3. it wouldn't be Substitution. You're not substituting anything, you're simplifying. I'd put simplify.

In parentheses (proven) beside it, just in case

Simplifying isn't one of the properties though. I figured that I would put substitute since I would be substituting 3 as for x.

You're not substituting 3 as x though, you just simplified it to get x=3. But yeah!, I'd go with "proven" :)

Okay, I have one more question. Would you mind helping me out with it?

For another problem that deals with this same situation; one of the steps is angle 4 = 110 degrees. I think it's corresponding property might be symmetric. What do you think?

vivalakodaBest ResponseYou've already chosen the best response.0
I disagree, symmetric property is if for example a=b, then b=a. If that information is already given to you and you're just listing it, it would be "given", but in order for me to say exactly what the property is I would have to see the rest of the problem.

They tell me to complete the twocolumn proof. (If you want me to draw the diagram let me know.) Given: angle 2 ≅angle 4, angle 2 = 110 degrees Prove: angle 3 = 70 degrees angle 2 ≅angle 4, angle 2 = 110 degrees a. Given angle 4 = 110 degrees b. ________ angle 4 + angle 3 = 180 degrees c.____________ angle 3 = 70 degrees d. ___________

I think that c is the Addition Property of Equality possibly.

I don't think that that deals with proofs though..

Theorems and postulates? Are you familiar with those?

Fang02Best ResponseYou've already chosen the best response.0
I know about the Pythagorean Theorem for sure. I can't remember that much about postulates right now.

Well, postulates and theorems are used to justify proofs.
