    Step-by-step explanation:

    Evaluate r + 42 / (t 3) where r = 24 and t = 6:

    r + 42 / (3 t) = 42 / (6*3) + 24

    42/6 = (6*7) / 6 = 7:

    7/3 + 24

    Put 7/3 + 24 over the common denominator 3. 7/3 + 24 = (3*24) / 3 + 7/3:

    (3*24) / 3 + 7/3

    3*24 = 72:

    72/3 + 7/3

    72/3 + 7/3 = (72 + 7) / 3:

    (72 + 7) / 3

    72 + 7 = 79:

    Answer: 79/3
