\(\left(4,5-2x\right):\dfrac{3}{4}=1\dfrac{1}{3}\)
\(4,5-2x=\dfrac{4}{3}\cdot\dfrac{3}{4}\)
\(4,5-2x=1\)
\(2x=4,5-1\)
\(2x=3,5\)
\(x=3,5:2\)
\(x=1,75\)
d,\(\left(\dfrac{2}{3}-\dfrac{1}{4}+\dfrac{5}{11}\right):\left(\dfrac{5}{12}-1-\dfrac{7}{11}\right)\)
Giúp mik nha, mik cần gấp:>
Tìm x:
d) \(\dfrac{-5}{6}-x=\dfrac{7}{12}+\dfrac{-1}{3}\)
e) \(\dfrac{x+3}{-15}=\dfrac{1}{3}\)
f) \(\left(4,5-2x\right).\left(-1\dfrac{4}{7}\right)=\dfrac{11}{14}\)
\(A=1+\dfrac{1}{2}+\left(\dfrac{1}{2}\right)^2+\left(\dfrac{1}{2}\right)^3+.......+\left(\dfrac{1}{2}\right)^{2022}\) Giups mik với mik cần gấp ạ
\(A=\dfrac{3}{x+2} B=\dfrac{-11}{2x-3} C=\dfrac{x+3}{x+1}D=\dfrac{2x+10}{x+3}\)
giúp mik với mn nếu ai trả lời đc thì cho mik cảm ơn nha
Mik đg cần
