-34=k×2
k= -17
85= -17× X
X= -5
This formula only applies if the track is circular. If it is, then we write the equation:
2*r*pi=400
Dividing by 2pi, we see that:
r=200/pi
This is approximately 63.66.
18?
-18 divided by [-1/6]
is 18
hopefully that's what you were looking for.?!!
8n- (2n-3) =12
8n-2n= 12+3
6n=15
n= 2.5
Hope this helps :)
