Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k

pV = nRT
solve for R

• R= pV/nT
• R= p/n + V/T
• R= pV - nT
• R= (pV-n)/T

Formula for the surface area of a cylinder is SA =  $2\pi r^2$   +  $2\pi rh$  , solve for h 

•  $h\ =\ \frac{SA\ -\ 2\pi r^2}{2\pi r}$  

•  $h\ =\ SA\ +\ 2\pi r^2\ \times2\pi r$  

•  $h\ =\ \frac{SA\ -\ 2\pi r}{2\pi r^2}$
