24 x 21 is 504. to make a model, just make it 24 x 21 (length x width)
There's some unknown (but derivable) system of equations being modeled by the two lines in the given graph. (But we don't care what equations make up these lines.)
There's no solution to this particular system because the two lines are parallel.
How do we know they're parallel? Parallel lines have the same slope, and we can easily calculate the slope of these lines.
The line on the left passes through the points (-1, 0) and (0, -2), so it has slope
(-2 - 0)/(0 - (-1)) = -2/1 = -2
The line on the right passes through (0, 2) and (1, 0), so its slope is
(0 - 2)/(1 - 0) = -2/1 = -2
The slopes are equal, so the lines are parallel.
Why does this mean there is no solution? Graphically, a solution to the system is represented by an intersection of the lines. Parallel lines never intersect, so there is no solution.

Answer:
x = 23.1
Step-by-step explanation:
The parallel lines make the left segments proportional to the right segments. This lets us write the equation ...
x/14 = 33/20
Multiplying by 14, we get ...
x = 14(33/20) = 7(33/10) = 23.1
.05 is equal to 5%
So for every dollar the mark up is .05cents
So if you times $81 by .05 this will give you the mark up because each of the 81$ needs .05 added to it.
So $4.05 Is the mark up
And
The cost would be markup and original added together
Answer:
Hence, the correct option is 82%.
Step-by-step explanation:
Consider the provided information.
In your university nursing program the ratio of students who scored a grade of A vs B vs C on the final exam is 12:29:9.
We need to find the percentage of student who scored a grade of "B" or higher.
Let x is the common factor for the proportion.
Then, the number of students who got grade A is 12x
The number of students who got grade B is 29x
The number of students who got grade C is 9x.
Thus the total number of students = 12x+29x+9x = 50x
The percentage of student who scored a grade of "B" or higher:
12x+29x = 41x
Hence, the correct option is 82%.
