Question

4.8/2z+15=0.2/5 Plz help I am only 8

Answer 1

Answer:  z = 247.5

Step-by-step explanation:

4.8/2z+15=0.2/5 To eliminate the denominators, multiply both sides by their reciprocals.

2z(5)(4.8/2z+15)=2z(5)(0.2/5)  Denominators "cancel." Distribute 5(4.8 + 15)

24 + 75 = 2z(0.2)    Simplify: Add  24+75=99 and Multiply 2z×0.2= 0.4z

99 = 0.4z .  Divide both sides by 0.4

99/0.4 = 0.4z/0.4 .   0.4  "cancels" on the right. dividing by a decimal is like multiplying by its reciprocal, 10/4 × 99

247.5 = z
