Question

I'm a junior and am having a difficult time understanding algebra II

Answer 1

I'm doing proportions 3/2 = 9/x

Answer 2

6

Answer 3

can you show me how you got that answer

Answer 4

just think. 3 times what is nine?

Answer 5

ok so will I multiply 3/2 x 3 to get 9/x?

Answer 6

\[\frac{3}{2}=\frac{9}{x}\]
cross multiply
3x=18
divide by 3
x=6

or
\[\frac{3}{2}=\frac{9}{x}\]

multiply both sides by x
\[\frac{3}{2}x=9\]
then multiply both sides by 2
3x=18
divide by 3

x=6

Answer 7

thank you

Answer 8

evaluate the function
f(c)=$1.19x15

Answer 9

makes no sense
you have a function in terms of c
with no c in it
and im not sure if the x is a variable or a multiplication sign

Answer 10

sorry
let C =cost/bottle
f(c)=total cost

I may have figured it out
