Question

Tim x biet

e) \(\frac{11}{8}+\frac{13}{6}=\frac{85}{x}\)

f)   \(2x-\frac{2}{11}=1\frac{1}{5}\)

Answer 1

\(\frac{11}{8}+\frac{13}{6}=\frac{85}{x}\)

\(\frac{85}{24}=\frac{85}{x}\)

\(x=24\)

\(2x-\frac{2}{11}=1\frac{1}{5}\)

\(2x-\frac{2}{11}=\frac{6}{5}\)

\(2x=\frac{76}{55}\)

\(x=\frac{38}{55}\)

Answer 2

a. \(\frac{11}{8}\)+ \(\frac{13}{6}\)= \(\frac{85}{x}\)

                    \(\frac{85}{24}\) =\(\frac{85}{x}\)

                             x   = \(\frac{24\cdot85}{85}\)

                             x   = 24

b. 2x - \(\frac{2}{11}\)=1\(\frac{1}{5}\)

     2x- \(\frac{2}{11}\)= \(\frac{6}{5}\)

     2x             = \(\frac{6}{5}\)+\(\frac{2}{11}\)

       x             = \(\frac{76}{55}\): 2

       x             = \(\frac{38}{55}\)

Answer 3

e, \(\frac{11}{8}+\frac{13}{6}=\frac{85}{x}\)

\(\Leftrightarrow\frac{85}{24}=\frac{85}{x}\)

\(\Leftrightarrow x=24\)

Vậy.......................
