Solve for x.

2/3x = 27

x = 81/2

Step-by-step explanation:

hope this helps, have a great day/night!!

x = 81/2 or Simplified 40 1/2

The midpoint is (2.5,4.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2

(4+1)/2 = 5/2 = 2.5

To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2

(6+3)/2 = 9/2 = 4.5

The midpoint is (2.5,4.5)
