Answer:
10 - 3x
Step-by-step explanation:
Since the number 10 is decreased by 3x, that would mean the expression is 10 - 3x.
Hope this helped!
Let the missing number be x
Mean is the total sum of data over the number of data therefore,
(11+20+x+3+1) / 5 = 9
Then simplify
(35 + x) / 5 = 9
Then multiply 5 to both sides
35 + x = 45
Then subtract 35 to both sides to find x
X= 10
