Answer:
3
Step-by-step explanation:
The way to figure out if it is a triangle or not is by using the triangle inequality theorem. It says that the sum of 2 sides of the triangle must be larger than the third side. Therefore, there are 3 triangles that we can make with the side lengths of 3ft, 4ft, and 5ft.
STUDENTS X 10
FACULTY 100-X 25
10X + 25(100-X) = 1300
10X + 2500 -25X = 1300
10X - 25X = -2500 + 1300
-15X = -1200
15X = 1200
X = 1200/15
