Okay this is very simple
The length of the longest lead is 1 3/4
The length of the shortest lead was 1/4
The difference between the longest lead and the shortest lead is 1 1/2
The length the most students had was 1/2
The of the sum of the two shortest lengths are 3/4
The difference of the longest lead and the second shortest lead is 1 1/4
hope this helps :)

Answer:
n=-2
Step-by-step explanation:
1−(2n+9)=4(1−2)
1+−1(2n+9)=4(1−2)
1+−1(2n)+(−1)(9)=4(1−2)
1+−2n+−9=4(1−2)
1+−2n+−9=−4
(−2n)+(1+−9)=−4
−2n+−8=−4
−2n−8=−4
−2n−8+8=−4+8
−2n=4
Divide both sides by -2
-2n/2=4/-2
n=-2
