Answer:

1240

Step-by-step explanation:

the ratio is 11:9

let the number of girls be x, then the number of boys is x + 124

now

$\frac{x+124}{x} = \frac{11}{9}$

9x + 1116 = 11x

2x= 1116

x=558

so total number = x + (x+124) = 1240

Kim solved the equation below by graphing a system of equations. log base 2 (3x-1) = log base 4 (x+8)

kompoz [17]

Answer:

solution is

$x=1.353,y=1.613$

Step-by-step explanation:

We are given equation as

$log_2(3x-1)=log_4(x+8)$

Firstly, we will find equations

First equation is

$y=log_2(3x-1)$

Second equation is

$y=log_4(x+8)$

now, we can draw graph

and then we can find intersection point

we can see that

intersection point is (1.353,1.613)

so, solution is

$x=1.353,y=1.613$
