Answer:
There are 25 students in the class.
Step-by-step explanation:
Let x be the number of students in the class
12% failed and the number of students is 3
x*12% = 3
x*.12 = 3
Divide each side by .12
x * .12 /.12 = 3/.12
x =25
There are 25 students in the class
If your just looking for x then x=2

Answer:
32
Step-by-step explanation:
you just have to divide 131/4 to get 32.75 but they all have to be equal
- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1
at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c
c = -1 -1
c = - 2
equation:
y = -x -2
y + x = -2 or - x - y = 2
