Dose anybody know the answer?

they want a fomula that is in respect to 'b"  sooo..

Step-by-step explanation:

just do the algebra like so..

a/b=c

move 'b" across = sign by multiplying by 1/b  like soo.

(1/b)*(a/b)=  (1/b)*c

a=c/b

then move the 'c' to the other side of the = sign  by multiplying by 1/c

(1/c)*a = (1/c)*(c/b)

a/c = b    

makes sense  , also.. as a way to speed that up.. just remember you can just swap the  'b'  and 'c'  in that first equation  

b = a/c

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
