Answer:
2y - 12x = 3
Step-by-step explanation:
gradient of line PQ= (7-8)/ 4+2
-1/6
gradient of perpendicular bisector of line PQ=
-1 ÷ -1/6
-1× -6
6
coordinates of the midpoint of line PQ
(-2+4)/2, (8+7)/2
(1, 15/2)
the perpendicular bisector passes through the midpoint of line PQ
Equation of the perpendicular bisector
y - 15/2 = 6(x - 1)
multiply through by 2
2y - 15 = 12(x - 1)
2y - 15 = 12x - 12
2y - 12x = 3

Answer:
no
Step-by-step explanation:
3/4=0.75
1/2+n=0.5
You need to add 1 3/4, 2 1/3, and 2 3/4.
But before you do that you need to make them decimals.
Add 1.75, 2.33, and 2.75
Equals 6.83
Then subtract it by 20.00
Equals 13.17
Then you make that a decimal
13 17/100
