for every girl taking classes at the martial arts schools there are 3 boys who are taking classes at the school. if there are 23

Yuliya22 [10]

You have to be very careful how you set this up. For every girl (who counts as 1) there are 3 boys (who count as 3). The total number in the proportion is 3 + 1 =4. You are given a total, but that is both boys and girls. That's why you need the 4.

3/4 = x / 236 Cross multiply

4x = 3 * 236

4x = 708 Divide by 4

x = 708/4

x = 177

There are 177 boys at the school and 236 - 177 = 59 girls.

Find the domain of the rational expression: x-4/2x-6

marin [14]

Answer:

All real numbers except 3

Step-by-step explanation:

Given

$\frac{x - 4}{2x - 6}$

Required

Determine the domain

We start by writing the following inequality

$2x - 6 \neq 0$

Add 6 to both sides

$2x -6 + 6 \neq = 0 + 6$

$2x \neq 6$

Divide both sides by 2

$\frac{2x}{2}\neq \frac{6}{2}$

$x \neq \frac{6}{2}$

$x \neq = 3$

<em>As such, the domain of x is all real numbers except 3</em>
