right so that side is five times as large
do the same thing to 11 to find \(x\)

Answer 9

you are keeping me in suspense

Answer 10

55. (: thank you. I could really use $12 too.. lol

Answer 11

could you help me on one more?

Answer 12

if you want to set it up as a ratio, you have lots of choices
\[\frac{x}{30}=\frac{11}{6}\] would be one
\[\frac{x}{11}=\frac{30}{6}\] would be another and probably an easier one since \(\frac{30}{6}=5\)

Answer 13

sure but if it is that easy you have to give the $12 back
