Step-by-step explanation:

3 1/8=3.8+1/8=25/8

25/8-4/7

25.7/8.7-4.8/7.8

175-32/56

143/56

2 31/56

The answer is 2 and 1/2 I got it right on my unit test review.

Step-by-step explanation:

$9.41

step-by-step explanation:

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 )
