77/20 = 3.85 <== terminating decimal
Use the formula
n(n-1)/2
which is the total number of connections between n points
So,
4(3)/2 = 6
the answer is option C.
Hope this helps
The appropriate response is the third one. A Cartesian organize framework is an arrange framework that determines each point exceptionally in a plane by a couple of numerical directions, which are the marked separations to the point from two settled opposite coordinated lines, measured in a similar unit of length.

Answer:
14 and 8
Step-by-step explanation:
Solution set:
x+y=22
4x=7y
Solving:
4(22-y)=7y
88-4y=7y
88=11y
8=y
8+14=22
