At one time the student-to-faculty ratio at centennial academy was 17 : 3 . the total number of students and faculty was 740. how many faculty members were there? how many students were there?

The number of faculty was 3/(17+3) = 3/20 of the total of students and faculty.

The number of faculty members was (3/20)·740 = 111.

The number of students was 740 - 111 = 629.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
