Print processes, sorted by usage of CPU

I need to print the 10 processes that are using the most CPU. Also I need to print their ID, and the command they were started with.
What I've found is that the command ps -ax -u prints all the processes and their %CPU usage. The command ps -ax -u --sort pcpu prints all the processes sorted by the %CPU usage, from the least to the most, but I need to print only 10 processes from the most to the least. I have to use something like sort -r to make a reverse sorting, but the command ps -ax -u --sort -r pcpu produces an error.
So, how can I make a reverse sorting and print only 10 of the processes?

to print 10 processes, that use the most CPU
ps -aux --sort -pcpu | head
Sorting syntax is
[+|-]key[,[+|-]key[,...]].
The "+" is
optional since default direction is increasing numerical or
lexicographic order. Identical tok. For example:ps jax --sort=uid,-ppid,+pid
head - will print the first/top 10 lines of file(s) or standard input (by default)

And, for example, if I need not 10, but 15 lines, I will need to writehead -n 15?
