Question

A certain drug is made from only 2 ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 2 milliliters of compound B. If a chemist uses 222 milliliters of compound A, how many milliliters of the drug will be made?

Answer 1

Answer: im guessing you need the amount of compound b

Explanation:

1 think out problem

compound A =222m compound B=3 milliliters of compound A used for every 2 milliliters of compound B

write compound B as an equation which is:

a=3+2b

compound a equation is: a=222

to continue you have to make compound B equation equal b

a=3+2b

-2b -2b

a-2b=3

-a -a

-2b/-2=3/-2-a/-2

b= -3/2+a/2

i am working on the substitution method: so now you substitute variables

problems are: b=-3/2+a/2 and a=222

substute a for a: b=-3/2+222/2

b=109.5

a=222

compound A=222

compound B=109.5

add both for final answer or whatever: 109.5+222= 331.5

sorry for the long complicated answer hope you understand. i tried my best it should be right. sorry if my answer is wrong.
