Answer:
60 milligrams
Step-by-step explanation:
just cross multiply! percentages are just fractions of 100. so you can say that 
multiple 75 by x and 45 by 100 and you get
4500=75x
divide both sides by 75 and you get 60
Answer: ok so for 5 and 125 it is 65 and 25
for 1 and 9 it is 5 and 3 and for 4 and 9 it is 13/2 and 6
It will have 2 solutions! this is because a negative and a negative cancel each other out and will make a positive under the radical.
Your answer is 38 I hope its correct :)
