Answer:
80 ÷ 4 = 20, so 100 ÷ 4 = 25 students
Step-by-step explanation:
Is means equals to and of means multiply
20 = 80% * N
20 = .80 N
Divide each side by .8
20 / .8 = N
25 = N
there are 25 students
Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.
Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.
So, X intercept - (2,0)
Y intercept - (0,3).
Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.
Now put everything together in form:
Y = mx + b
Y = -3/2x + 3.
I believe this is the solution.

17=5k-2
add 2 to both sides
19=5k
divide both sides by 5
19/5=k
19/5=3 and 4/5
Answer:
(m+2)(m-2)=m^2-4
Step-by-step explanation:
(m+2)(m-2)=m(m-2)+2(m-2)
=m^2-2m+2m-4
=m^2-4
