If y varies jointly as w and x, and y is 483 when x is 742 and w is 383, find y when x is 274 and w is 756.

  • Algebra II -

    y = kwx

    First, find k. Do this by plugging in x,w,y:

    483 = k*742*383 so
    k = 0.0016995

    Now, knowing k, find y:

    y = 0.0016995 * 274 * 756
    y = 352
