Question

Tìm x:

( 3/4+x)x1/2=4/5

Mn giải hộ mk vs😉

Answer 1

\(\left(\frac{3}{4}+x\right).\frac{1}{2}=\frac{4}{5}\)

\(\frac{3}{4}+x=\frac{4}{5}:\frac{1}{2}\)

\(\frac{3}{4}+x=\frac{8}{5}\)

\(x=\frac{8}{5}-\frac{3}{4}\)

\(x=\frac{17}{20}\)

Answer 2

(3/4+x)x1/2=4/5

(3/4+x)      =4/5:1/2

3/4+x        =8/5

         x       =8/5-3/4

         x=17/20

Vậy x là 17/20

k cho mk nha

Answer 3

\(\left(\frac{3}{4}+x\right)X\frac{1}{2}=\frac{4}{5}\)

\(\frac{3}{4}+x=\frac{4}{5}:\frac{1}{2}\)

\(\frac{3}{4}+x=\frac{8}{5}\)

\(x=\frac{8}{5}-\frac{3}{4}\)

\(x=\frac{4}{15}\)

nhé

Answer 4

\(\left(\frac{3}{4}+x\right)x\frac{1}{2}=\frac{4}{5}\)

\(\frac{3}{2}+x=\frac{4}{5}:\frac{1}{2}\)

\(\frac{3}{4}+x=\frac{8}{5}\)

\(x=\frac{8}{5}-\frac{3}{4}x=\frac{17}{20}\)
