Set up a ratio:

9 / 2x-1 = 15 / 3x

Cross multiply:

9 *3x = 15 * 2x-1

Simplify:

27x = 30x - 15

Subtract 30x from both sides.

-3x = -15

Divide both sides by -3:

x = -15 / -3

x = 5

Answer:

$a\frac{c}{8\pi b}$

Step-by-step explanation:

Divide both sides by $8\pi b$

$\frac{8\pi ab}{8\pi b} =\frac{c}{8\pi b}$

Simplify:

$a\frac{c}{8\pi b}$ ; $a\frac{c}{8\pi b}; b\neq 0$

Do anyone know how to solve this? need the answer fast.

The value of g^-1(-3) is the value of x that makes g(x) = -3. To find it, we can solve
.. (x +4)/(2x -5) = -3
.. x +4 = -3(2x -5)
.. 7x = 11
.. x = 11/7

The desired value is
.. (3/11)*g^-1(-3)
.. = (3/11)*(11/7)
.. = 3/7

$\frac{3}{11} g^{-1}(-3) = \frac{3}{7}$
