Step-by-step explanation:
-12 = 3/4n + 8....subtract 8 from both sides
-12 - 8 = 3/4n
-20 = 3/4n.....multiply both sides by 4/3, cancelling the 3/4 on the right
-20 (4/3) = n
-80/3 = n
ur answer is A

Answer:
A. (1.55, 2)
Step-by-step explanation:
The formula to apply when finding the midpoint of a segment where the coordinates of the end points are given is;

where (x₁,y₁) and (x₂,y₂) are the coordinates of the end points
Given;
x₁= -0.4 ,y₁=2.5, x₂=3.5, y₂=1.5 then applying the formula for midpoint

0.54=0.54/1=5.4/10=54/100=27/50
