Solve the equation. -1/3(4+z)=-5/6. Z=what?

-3/2=z

Step-by-step explanation:

multiply 4 and z by -1/3 to get

-1/3z - 4/3= -5/6

then add 4/3 to both sides to get

-1/3z= 3/6

then divide both side by -1/3 to get

z=-3/2

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
