30% of 300 would be 90 students.

Therefore we have 210 students left remaining who did not bring their lunch.

Does anyone know how to do this?? steps are helpful but not necessary

Answer:

C. $\frac{2(x+16)}{x+4}$

Step-by-step explanation:

We want fg of x, so first we have to multiply f(x) times g(x).

$\frac{x+16}{x} * \frac{2x}{x+4}$

$\frac{(x+16)2x}{x(x+4)}$

$\frac{2x^{2}+32x}{x^{2}+4x}$

We can cancel out an x from every term.

$\frac{2x+32}{x+4}$

Let's rewind a little to get this into one of the answer choices.

$\frac{2(x+16)}{x+4}$ is our answer.

for each babysitting job anna charges 2.50 for bus fare plus $8 per hours she worked. She charged 3.50 for her last babysitting

julsineya [31]

8x+2.50=3.50
-2.50 -2.50 subtract both sides by -2.50
8x=1
8. 8 divide both sides by 8
x=1/8
