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
i would guess "substitution" since that is what you did, substituted 15 for C
it is substitution property because u r substituting 15 for C.
