Michaela wrote the following. if p + 9 = 25 and p = q, then q + 9 = 25. which property did michaela show?
a) symmetric property of equality
b) multiplication property of equality
c) substitution property of equality
d) reflexive property of equality

The correct option is C.

Step-by-step explanation:

The given equation is

                 .... (1)

and

                       ...(2)

According to the  substitution property of equality, if we have two equation then we can substitute the values form one equation to another equation.

Equation 2 represent that the value p and q are equal.

Using substitution property of equality the first equation can be written as

Therefore Michaela use substitution property of equality and option C is correct.
