The mean is 9.6
3+8+10+12+15= 48/5= 9.6
I've already been complemented twice on my previous answer, but then I discovered that I mis-read the question. My entire original answer was wrong, and I have to delete it.
I don't believe that any number can satisfy both of those conditions.
I'll say the question has no answer.
The two numbers are 12 and 16. 12 + 6 = 18. 6 doubled is 12. 12 plus 6 equals 18.
Answer:
30
Step-by-step explanation:
2700/90 = 30
27/9 = 3
100/10 = 10
3*10 = 30
27 divided by 15 is 1.8, so that should be the correct answer.
