during a clinical study, a medical company found 3 out of 70 people experienced a side effect when using a certain medicine. The company predicts 63,000 people will use the medicine next year. How many people are expected to experience a side effect?
3/70=x/63000
18900=70x
x=2700
is this correct? thanks
Ms. Sue what are you smoking??!!
honestly im from 2019 but this is hilareous so i hope yall keep up the hot debate
Yes, that's right.
Ms. Sue no it isn't!!
Elle you need to divide 70 of each side! your equation will be 18900/70=70x/70
then for your final answer: you will get x=270
3/70=x/63000
Cross multiply.
70x = 189,000
x = 2,700
Anonymous, that not very nice! but Ms. Sue why would you cross multiply? you should just divide to get x by itself. and get x=270 just like Anonymous said
Anonymous/Country cutie -- why are you talking to yourself?
