A certain drug is made from only 2 ingredients: compound A and compound B. There are 3 milliliters of compound A used for every
defon

Answer: im guessing you need the amount of compound b


Step-by-step 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

<u>compound A=222</u>

<u>compound B=109.5</u>

<u>add both for final answer or whatever: 109.5+222= 331.5</u>

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