## Godsgirl 3 years ago Suppose you must find the termperature in degrees Fahrenheit F when it is 15º C. You would solve the equation F = (9/5)C + 32 for F. Your next logical step would be F = (9/5)(15) + 32. Why? A: Addition Property of Equality B: Multiplication Property of Equality C: Substitution Property of Equality D: Division Property of Equality

not happy with the last answer? i still think it is C, since you are "substituting" 15 for C

2. No-data

I did not know it was called Substitution Property of Equality.

3. TuringTest

C is the only one that makes sense..

4. No-data

But If you understand what variables and linear equations are, sure you won't have problems, chooseing the roght answer.

5. No-data

That is C, like TT said.

6. satellite73

frankly i didn't know that either, but it seems to be the only one that makes sense

7. Godsgirl

okay i was just not sure if it was and satellite73 i was just getting another persons opinion

8. satellite73

fair enough

9. No-data

I think that everyone here agrees =).

10. Godsgirl

@satellite73 did that get you mad??
