1) Answer:
[tex]h = \frac{3}{2} [/tex]
2) Answer:
[tex]a = \frac{160}{3} [/tex]
3) if you mean,
[tex] \frac{3}{5} x = 12[/tex]
Then the answer is. x = 20.
but, if you mean
[tex] \frac{3}{5x} = 12[/tex]
then the answer would be, x = 1/20.
4) Answer:
[tex]y = \frac{5}{7} [/tex]
5) If you mean,
[tex] \frac{14}{3} = - \frac{7}{9b} [/tex]
then the answer would be, b = -1/6
but if you mean,
[tex] \frac{14}{3} = - \frac{7}{9} b[/tex]
then the answer would be, b = -6
