    Reduce into simpler circuits.

    Look for resistors in series, and simply add them together:
    Rt = Rx + Ry : (150 ohms = 100 ohms + 50 ohms)

    Look for resistors in parallel and use the following:
    Rt = 1 / [(1/Rx) + (1/Ry)] : (33.33 ohms = 100 ohms || 50 ohms)

    : when using a calculator for parallel resistance, just invert (1/x) any resistor values, add them together, then invert again.

    Go ahead and post your efforts to solve any one of the problems and then the members can assist you with any errors that are keeping you from getting the correct answer.
