18 points scored for a pair was 40 % of the final score
then final score is 100%
therefore if 40 % accounts for 18 points
100 % = 18 / 40% *100%
= 45 points is the final score
if we back calculate = 18 /45 *100 = 40%
Therefore the final score is 45 points

x=-7
Answer:
AD = 5 units
Step-by-step explanation:
Given:
Perimeter = 18 units
BC = 4 units
CD = 3 units
Required:
Length of segment AD
Solution:
Perimeter = AB + BC + CD + AD
We can easily find AB,
AB = 6 units (distance from A to B)
Plug in the values
18 = 6 + 4 + 3 + AD
18 = 13 + AD
Subtract 13 from each side
18 - 13 = 13 + AD - 13
5 = AD
AD = 5 units
