tui có kks 6 bọt biển 5 pika 5 sát thủ 6 lego 5 Noen 6

ko hiểu

Ta có:

\(\dfrac{1}{4}+\dfrac{8}{9}=\dfrac{41}{36}\)

\(1-\left(\dfrac{3}{8}-\dfrac{5}{6}\right)=\dfrac{35}{24}\)

ta lại có:

\(\dfrac{41}{36}=\dfrac{82}{72}\)

\(\dfrac{35}{24}=\dfrac{105}{72}\)

\(\Rightarrow\)82 \(\le\)2x < 105

\(\Rightarrow\)41\(\le\)x<52.5

Vậy 41\(\le\)x<52.5
