Step-by-step explanation:

(3, -3/2)
Answer:
x = 9
27, 45, 54
Step-by-step explanation:
The mean of 6x, 3x and 5x = 6x + 3x + 5x / 3 = 14x / 3 = 4 2/3x
The mean of 40, 50 and 36 = 40 + 50 + 36 = 126/3 = 42
4 2/3x = 42
x = 42÷14/3 = 42 * 3/14 = 9
6x = 54
3x = 27
5x = 45
Least to greatest order: 27, 45, 54
Hope this helps :)
