Answer:
x = 16
Step-by-step explanation:
Since the numbers are in ascending order, x is the number with the highest value here.
From the arrangement, we can see that the median (the middle number) is the third number which is 9
The mean is the sum of the numbers divided by their count. So we set up the mean and equate to the median
We have this as;
(1 + 9 + 9 + 10 + x)/5 = 9
29 + x = 5(9)
29 + x = 45
x = 45-29
x = 16

Answer:
6
Step-by-step explanation:
Given
3x - 15 ≥ 3 ( add 15 to both sides )
3x ≥ 18 ( divide both sides by 3 )
x ≥ 6
Since x is greater than or equal to 6 then 6 is a solution
