    Answer:

    The polar bear weighs 525kg

    Step-by-step explanation:

    C = Polar Bear

    D = Baby Elephant

    ____________________________

    (1)  C + D = 700 kg

    (2)  C = 3D

    ________________________________

    C = 700 – D

    700 – D = 3D

    700 = 4D

    ________________________________

    525 + 175 = 700

    Then we get our answer, the polar bear weighs 525kg, and the baby elephant weighs 175kg.

    Hope this helps you 🙂
