I know Im beat on the turn, but what do i do on the river

[aargh57]

but should you call the turn given that? On the turn you gotta figure you're gonna have to
1)pay 2 bets
2)hit a A,9,7,T,or Q to continue and of those none of them are giving you the nuts so they're all partial outs.

How many outs do we give each? There are 2 Ace's and 3 of each of the others left. I'd say it would be generous to give each card more than 1/2 of an out each. That would give us 2.5 outs. A clear fold on the turn. Is my thinking correct here? Should I even be thinking of this problem in this way?
