Answer 8

\[7*\frac{1}{5}+p+4*\frac{9}{10}+3*\frac{3}{20}=19*\frac{1}{10}\]\[7*\frac{4}{20}+p+4*\frac{18}{20}+3*\frac{3}{20}=19*\frac{2}{20}\]\[\frac{28}{20}+p+\frac{72}{20}+\frac{9}{20}=\frac{38}{20}\]\[p+\frac{109}{20}=\frac{38}{20}\] \[p=-\frac{71}{20}\]

Answer 9

\[\frac{z}{12}=6*\frac{3}{4}\]\[\frac{z}{12}=\frac{18}{4}\]\[z=\frac{18*12}{4}\] \[z=\frac{216}{4}=54\]
