Answer:

z = 52.5

Explanation:

You want the solution for (4.8)/(2z+15)=(0.2)/(5).

Cross multiply

Multiplying by 5(2z +15) we have ...

5(4.8) = 0.2(2z +15)

24 = 0.4z +3 . . . . . . . . . . simplify

21 = 0.4z . . . . . . . . . . . . subtract 3

z = 21/0.4 = 52.5 . . . . divide by the coefficient of z

The value of z is 52.5.
