Well... Yes. But it's better use some more descriptive names (usually in uppercase) and export them. Add something like this in your profile:
Code:
APACHE_N=`...`
export APACHE_N

But these values will be constant. Maybe it's better to use aliases:
Code:
alias ca='/usr/bin/svcs -a |grep apache22 | wc -l'
alias pw='ps -ef | grep wls[a]dmin | grep -v "grep" | wc -l'

Then:
Code:
echo $((`ca`+`pw`))

It will work only on the command line not in scripts.
