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

Best ResponseYou've already chosen the best response.0I 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.

Best ResponseYou've already chosen the best response.0My 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.'

Best ResponseYou've already chosen the best response.0For x=3. it wouldn't be Substitution. You're not substituting anything, you're simplifying. I'd put simplify.

Best ResponseYou've already chosen the best response.0In parentheses (proven) beside it, just in case

Best ResponseYou've already chosen the best response.0Simplifying isn't one of the properties though. I figured that I would put substitute since I would be substituting 3 as for x.

Best ResponseYou've already chosen the best response.0You're not substituting 3 as x though, you just simplified it to get x=3. But yeah!, I'd go with "proven" :)

Best ResponseYou've already chosen the best response.0For 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?

Best ResponseYou've already chosen the best response.0I 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.

Best ResponseYou've already chosen the best response.0They 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. ___________

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

Best ResponseYou've already chosen the best response.0Well, postulates and theorems are used to justify proofs.
