Oct.

Step-by-step explanation:

average = (72 + 83 + 95 + 77 + 88)/5 = 83

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

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 )
