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 :)
