if m varies directly as n and m= 18 when n = 6, find the variation constant and the equation.

Sagot :

Answer:

the constant value is 3 and the equation is m = 3n

Step-by-step explanation:

m = kn

(substitute the values of m and n)

18 = k (6)

divide both sides by 6 to get

k = 3 (3 is the constant value)

now get our equation from above and substitute the constant value

we have now as our equation:  m = 3n

ps are you a grade 9 student haha
