Answer:
5
Step-by-step explanation:
To obtain the total score for all the 20 students, we multiply the average score by the number hence
Total score for all 20 is 81*20=1620
Similarly, for the 19 students, the sum of their total score equals the product of the average and number of students hence
Total score for 19 readable is 19*85=1615
The difference between these two total scores ie for 20 and 19 students equals to the value of unreadable score. Therefore,
Difference=1620-1615=5
Therefore, the value of unreadable score is 5

The naming of similar triangles has corresponding vertices in the same order in the name. That means segment QS corresponds to segment AC. We note that QS = 6 cm is 1/10 the length of AC = 60 cm.
Side AB is given as 50 cm, so the corresponding side QR will be 1/10 that value.
... QR = 5 cm
Step-by-step explanation:
assuming you meant line with a slope of 5.
y - -6 = -1/5(x-3)
y + 6 = -1/5x - 3/5
y = -1/5x - 33/5
