Answer:
(10,51)
Step-by-step explanation:
Take the average of 3 (x1) and 17(x2). This will be your new x-coordinate.
Then take the average of 21 (y1) and 81 (y2)
(3+17)/2 = 10
(21+81)/2 = 51
I assume you want the expression to this so it would be x-y-3
The answer is $3.57 because you must multiply 2.55 by 140 then divide that by 100 to find your answer hope this helps.
