Respuesta :
The first step into solving this equation should be, c dividing by both sides
Answer:
C; multiply 4 to both sides
Step-by-step explanation:
When you want to solve for a variable, you always want to isolate it.
So, to move 4, we have divide:
[tex]\frac{A}{4}[/tex] = [tex]\frac{4r}{4}[/tex].
The 4 in 4r is "one'd" out, and now we have 1r, or simply r.
Now, we have r = A/4
