Answer:
409
Step-by-step explanation:
18 x
--- = ---
22 500
18 x 500 = 9000
9000/22 = 409
Given:
The system of equation is


To find:
The solution of given system of equations.
Solution:
The slope intercept form of a line is

Where, m is slope and b is y-intercept.
Write the given equation in slope intercept form.
The first equation is


...(i)
Here, slope is
and y-intercept is 4.
The second equation is
...(i)
Here, slope is
and y-intercept is -4.
Since the slopes of both lines are same but the y-intercepts are different, therefore the given equations represent parallel lines.
Parallel lines never intersect each other. So, the given system of equation has no solution.
Hence, the correct option is B.
I would either use a histogram or a frequency chart, but histogram is easier and neater
