    Hi marksar

    T=\frac{175}{28}~\ln (1-\frac{V}{35})

    \ln (1-\frac{V}{35})=\frac{28}{175}T

    \log_e (1-\frac{V}{35}) = \frac{28}{175}T


    Hint :

    \log_a b = c \rightarrow b=a^c


    You can solve the rest questions using the same hint

    I dont know how to change the text to make them lok right but I'll give it my best try.

    35(((28/175T)/ln)+1)=-V
    I don't think your answer is right. Continuing my work and using the hint given :

    \log_e (1-\frac{V}{35}) = \frac{28}{175}T

     1-\frac{V}{35}=e^{\frac{28}{175}T}
