Respuesta :
z=1/5
Subtract 85 from both sides which gets you 25z=5.
Divide both sides by 25 which is z=5/25
Simplify which gives us the answer z=1/5.
Subtract 85 from both sides which gets you 25z=5.
Divide both sides by 25 which is z=5/25
Simplify which gives us the answer z=1/5.
Answer:
1/5 or 0.2
