Answer:

$1\frac{2}{3}$

Step-by-step explanation:

We want to simplify:

$2 \frac{1}{2} \div 1 \frac{3}{6}$

This is the same as:

$2 \frac{1}{2} \div 1 \frac{1}{2}$

Now let us convert the mixed numbers to improper fractions.

$\frac{5}{2} \div \frac{3}{2}$

We multiply by the reciprocal of the second fraction to get:

$\frac{5}{2} \times \frac{2}{3}$

Cancel out the common factors to obtain:

$\frac{5}{3} = 1 \frac{2}{3}$

Hello there!

To start off this problem, let's replace f(x) with x in the equation. This gives us the following.

$x= \dfrac{3}{4} x+12$

Subtract 3/4*x from both sides.

$x- \dfrac{3}{4} x=12$

$\dfrac{4}{4} x-\dfrac{3}{4}x=12$

$\dfrac{1}{4} x=12$

Now, multiply both sides by 4 to eliminate the fraction on the left side.

$x=12*4=48$

Your answer is B. Hope this helps! :)
