    Anyone who teaches me one word - even half a word - is still my teacher.
    2nd Version:
    Even he who teaches me the smallest bit can still be called my teacher

    Please correct my grammar as you see fit. Much appreciated!

    more= +

    X = 9 + 3y

    Therefore Y= X/3 - 3

    slope = m = 1/3

    Máy bay bay 250 mile hướng 377 độ (360/0 là hướng bắc, 180 là nam) rồi quẹo qua bay 130 mile hướng 67 độ. Khoảng cách giữa điểm đầu và cuối cách xa bao nhiêu mile ?

    Hint: giữa 377 và 67 độ là bao nhiêu ?
