Determining the size of conductors

[C-Elect]

If I have a 20 Amp breaker and my distance is 175 ft. away. The maximum operative load is 115 VAC and 9.0 Amps. This operates an ATM machine. Will a #10 AWG wire be sufficient?

Yes as Bryan said #10 will work just fine. You can try different size conductors here:
