Answer:
3.6
Step-by-step explanation:
The average of 9 scores is x.
average = (sum of scores)/(number of scores)
x = (sum of scores)/9
sum of scores = 9x
The sum of the 9 scores is 9x.
The tenth score is 36 more than x, so it is x + 36.
The sum of the 10 scores is 9x + x + 36 = 10x + 36.
The average of the 10 scores is (10x + 36)/10 = x + 3.6
The difference of averages is
x + 3.6 - x = 3.6

Hello there! :D
Find the scale of the sides.
40/5=8 (the longer side is 8 times bigger than the shorter one)
3*8= 24
2x+10=24
Subtract 10 on both sides.
2x=14
Divide by two on both sides.
x=7
I hope this helps!
