    Answer:No the student was not right. Neither of the estimations were right because she did not estimate at al.

    Step-by-step explanation:

    1. Round 49 to the nearest ten: 50.

    2. Round 184 to the nearest ten:180.

    3. Add 50+180 to get 230.

    The student was not right because she did not estimate 49 nor 184.
