Answer 11

yes

Answer 12

\(\large\color{black}{ \displaystyle \log(2x)+\log(5)=1 }\)

\(\large\color{black}{ \displaystyle \log(2x)=1-\log(5) }\)

\(\large\color{black}{ \displaystyle \log(2x)=\log(10)-\log(5) }\)

\(\large\color{black}{ \displaystyle \log(2x)=\log(10\div 5) }\)

\(\large\color{black}{ \displaystyle \log(2x)=\log(2) }\)

\(\large\color{black}{ \displaystyle2x=2 }\)

\(\large\color{black}{ \displaystyle x=1 }\)

you are correct!
