70 ohms and 30 ohms in parallel have a combined effective resistance of
( 1/70 + 1/30 )-1 = (70 x 30)/(70 + 30) = 2100/100 = 21 ohms

Is the circuit in series or parallel? If series then R = R1 + R2 + R3 (where R = Resistance) Or R = 20+20+10 = 50 = 50 Ohms If parallel then I/R = I/R1 + I/R2 + I/R3 (where I = Volts and R = Resistance) Or 5 ohms
