Answer:y=24 and x=10
Step-by-step explanation:
To find the value of x and y in x=3x-20 and y=-6+30

x-3x=-20
Divide through by -2
-2x=-20
x=10
The LCD is 24
2 * 8 16
3 * 8 24
5 * 3 15

2/3 is greater than 5/8
The averages are very different because there was a wide range of test scores among students
