Select the correct answer<br> Solve this equation<br> X+4/6x = 1/x
laila [671]

Answer:

A) x = 0, 2

Step-by-step explanation:

(x + 4) / 6x =  1 / x

this is a proportion, so you can cross-multiply and get:

x(x + 4) = 6x

x² + 4x = 6x

x² - 2x = 0

x(x - 2) = 0

x = 0

x - 2 = 0  so, x = 2

Answer:

Desiree outcomes..= 5 ( 17,34,51,68,85)

and therefore.. the probability is 5/90 = 1/18.

here you go.. that should be correct I hope.
