38.5
step-by-step explanation:
lets say, first number = r
second number = 3r+7
total = 49
(r)+(3r+7)= 49
4r+7 = 49
4r = 42
r = 42/4
r= 10.5
3r+7 = 3(10.5)+7 = 38.5
hope this
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
what is the original number? you forgot to add it.
