aaahhh i hate these kind of questions :P

Answer 2

same here. :b

Answer 3

k the formula for "y varies inversly with x" is \[y = k / x\]

Answer 4

so first you put in the values they told you about (y=3 and x=6) and solve for k

Answer 5

once you know k you set up another equation (using k=? and y =18)

Answer 6

am i making sense? :)

Answer 7

yes(:

Answer 8

so you get it?? :D

Answer 9

yes I do, thanks much! (:

Answer 10

k work it out and tell me what you get :)

2! :D

Answer 19

uh wat?

Answer 20

18 = 2

Answer 21

try that again :)

solve for x : 18=18/x

Answer 23

18/x = 18/6 = 3

Answer 24

no no

Answer 25

the only info you have is 18=18/x...now solve for x

Answer 26

ohhhh

Answer 27

so you would do 18=18/x......and get 18/18=x ....so x=? :D
