Why do you think that it is C?

shadow13 · Answer

well i dont know i took a guess

calculusxy · Answer

So the addition property of equality would be used in a case like this:
y - 5 = 3 
because the inverse operation of subtraction would be addition.

calculusxy · Answer

Do you still think it's C?

shadow13 · Answer

no now i think it is b is that right

calculusxy · Answer

I am not sure about the rest honestly. 
But here are some things that you should take into factor:
Symmetric: If a = b, then b = a
Transitive: If a = b and b = c, then a = c
Subtraction property of equality: it would be used in a case like where you have to do the inverse operation of addition.

But may I know what grade you're in?

calculusxy · Answer

...so that I can help you accordingly?

shadow13 · Answer

i am in 10th grade

calculusxy · Answer

Okay. 

So from the info that I gave you, what do you think you might want to cross out and why?

shadow13 · Answer

i think i should cross out c and d because we already know that it is addition and there is no multiplication in the problem.

calculusxy · Answer

I have a feeling that it can be B the remaining answer.

Explanation:
a = b and b = a 
-2 + 5 = 3 , where (-2 + 5) is "a" and 3 is "b" -- one way
3 = -2 +5 -- second way

shadow13 · Answer

ok well i know it is not a because b makes since on this question ill try that then

Which property is used in the statement?

if k/2 =5 then k = 10

multiplication property of equality
       symmetric property
       reflexive property
       subtraction property of equality

i thin k it is b but i change that i think it is c

shadow13 · Answer

the reason that i think that is because its not symmetric and i don't see any multiplying or subtracting so thats y i think it is C
