Answer:
21.4% of 855=182.97
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 855 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 855 is 100%, so we can write it down as 855=100%.
4. We know, that x is 21.4% of the output value, so we can write it down as x=21.4%.
5. Now we have two simple equations:
1) 855=100%
2) x=21.4%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
855/x=100%/21.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 21.4% of 855
855/x=100/21.4
(855/x)*x=(100/21.4)*x - we multiply both sides of the equation by x
855=4.67289719626*x - we divide both sides of the equation by (4.67289719626) to get x
855/4.67289719626=x
182.97=x
x=182.97
now we have:
21.4% of 855=182.97
Hope this helped :)

It's N=9 it's really confusing but trust me it N
Y = -4x + 13
y = mx + c ; m = -4 , c = 13
Let m be M1,
(M1)(M2) = -1
-4 (M2) = -1
M2 = 1/4
At P (-1,-2),
y = mx + c ; y = -2 , m = 1/4 , x = -1 , c = ?
-2 = (1/4)(-1) + c
c = - 7/4
Hence , the equation of the line is y = x/4 - 7/4
