Question

I'm confused. Please help.

Two questions:

Use the given property to complete the statement.
Transitive Property of Congruence
If line CD ≅ line EF and line EF ≅ line GH, then _______.

o line EF ≅line GH
o line EF ≅ line EF
o line CD ≅ line GH
o line CD ≅ line EF

Substitution Property of Equality

If y = 3 and 8x + y = 12, then _____________.
Choices:
o8(3) - y = 12
o3 - y = 12
o8x + 3 = 12
o8x - 3 = 12

I say it is 8x + 3 = 12. What do you think?

Answer 1

So, for question 1: Since CD is congruent to EF and EF is congruent to GH, that makes CD congruent to GH. Its the third choice.

For question 2: Your correct, 8x + 3 = 12 (choice three, again), is your answer.

Answer 2

Oh okay, I understand now. :) Thank you!

Answer 3

No problem @Fang02
