What is the area of the triangle formed by lines y=5−x , 2y=3x , and y=0 ?
7.5
8.0

The lines y = 5 - x and y = 3x/2 intersect when 5 - x = 3x/2, i.e. at point (2, 3)
The line y = 5 - x intersects y = 0 when 5 - x = 0 (because y = 0)
If we take the base of the triangle to be along the x-axis, its width is 5
and the perpendicular height is 3
Area = width x height /2 = 5 x 3 /2 = 7.5
