Step-by-step explanation:

$y = 2x - 24 \\ 4x = 3y \\ 2x = 1.5y \\ y = 1.5y - 24 \\ y - 1.5y = - 24 \\ 0.5y = 24 \\ y = 48 \\ x = \frac{3y}{4} = \frac{3 \times 48}{4} = 36$

x= apples =36 cents

y= pears =48 cents

HELP PLEASE!! I DONT UNDERSTAND!!!!!!!!!! THANKS SO MUCH

Hello, please consider the following.

We will multiply the numerator and denominator by

$4+\sqrt{6x}$

to get rid of the root in the denominator.

First of all, we cannot divide by 0, right? So, we need to make sure that the denominator is different from 0.

$4-\sqrt{6x} =0\sqrt{6x}=4\\\\\text{Take the square}\\\\6x=4^2=16\\\\x=\dfrac{16}{6}=\dfrac{8}{3}$

We need to take any x real number different from 8/3 then and simplify the expression.

Let's do it!

$\begin{aligned}\dfrac{4}{4-\sqrt{6x}}&=\dfrac{4(4+\sqrt{6x})}{(4+\sqrt{6x})(4-\sqrt{6x})}\\\\&=\dfrac{4(4+\sqrt{6x})}{(4^2-\sqrt{6x}^2)}\\\\&=\dfrac{4(4+\sqrt{6x})}{(16-6x)}\\\\&=\dfrac{2(4+\sqrt{6x})}{(8-3x)}\\\\&\large \boxed{=\dfrac{8+2\sqrt{6x}}{8-3x}}\end{aligned}$

Thank you

Answer:

Felicia's gross monthly income = $4,583.33 (Approx.)

Step-by-step explanation:

Given:

Annual income = $55,000
