Question

Solve for x in the proportion

Answer 1

\[\frac {9}{27x} = \frac {x}{x+3}\]

Answer 2

The bottom part is cut off on my screen >.< can you tell me what values are there?

Answer 3

What do you mean?

Answer 4

the denominator?

Answer 5

Yup, the denominators lol

Answer 6

the question is 9/27x = x/x+3

Answer 7

Oki lol lemme try this o.O but its been a whiile

9/27x = x/x+3

1/3x = x/x+3 (simplify 9/27)

1/3x * 3x(x+3) = x/x+3 * 3x(x+3) (multiply my the GCF)

x+3 = 3x^2 (simplify)
-x -x

3=3x^2-x
-3 -3

3x^2-x-3=0 (to solve for x we need to use the quadratic formula)

[-b +/- sqrt (b^2-4ac)]/2a (plug in values)

[1 +/- sqrt(1+36)]/6

x = 1+/- sqrt37/6

x = (1 - sqrt 37)/6 = -0.847

x = (1 + sqrt 37)/6 = 1.18

x ≈ −0.85 and x ≈ 1.18

Answer 8

Darn it totally messed up my format >.<
