A little confused here, why not just use SUM instead of COUNT and eliminate your GROUP BY?
Or make your existing select a group by
SELECT SUM(BRRCompletedApr13)
from (select COUNT(AdjustedDateCompleted) as BRRCompletedApr13
from dbo.shp_BRRPipelineRemediation
where AdjustedDateCompleted >='04/01/2013'
and AdjustedDateCompleted <'05/01/2013'
GROUP BY AdjustedDateCompleted )
