x = 4/5 : 3/4
x = 16/15
x = 5/9 : 8/3
x = 5/9 x 3/8
x = 5/24
\(x=\dfrac{4}{5}\times\dfrac{4}{3}\)
\(x=\dfrac{16}{15}\)
-----------------------
\(x=\dfrac{5}{9}\times\dfrac{3}{8}\)
\(x=\dfrac{5}{24}\)
\(x\times\dfrac{3}{4}=\dfrac{4}{5}\)
\(x=\dfrac{4}{5}:\dfrac{3}{4}\)
\(x=\dfrac{4}{5}\times\dfrac{4}{3}\)
\(x=\dfrac{16}{15}\)
\(\dfrac{5}{9}:x=\dfrac{8}{3}\)
\(x=\dfrac{5}{9}:\dfrac{8}{3}\)
\(x=\dfrac{5}{9}\times\dfrac{3}{8}\)
\(x=\dfrac{15}{72}\)
\(x=\dfrac{5}{24}\)
tìm x:
x + x * 1/9 : 1/3 + y : 1/3 = 1/5
\(x+x.\dfrac{1}{3}+3y=\dfrac{1}{5}\)
\(x.\dfrac{4}{3}+3y=\dfrac{1}{5}\)
\(x.\dfrac{4}{3}=\dfrac{1}{5}-3y\)
\(x=\left(\dfrac{1}{5}-3y\right):\dfrac{4}{3}=\dfrac{3}{20}-\dfrac{9y}{4}\)
tìm x:
X:1/3=1/2+1/3 (X:2/3):2/5=7/10
x : 1/3 = 1/2 +1/3
=>x:1/3=5/6
=>x=5/6 x 1/3
=>x=5/18
(x:2/3):2/5=7/10
=>x:2/3=7/10 x 2/5
=>x:2/3=7/25
=>x=7/25x2/3
=>x=14/75
CHÚC BẠN HỌC TỐT
tìm x:
X:1/3=1/2+1/3 (X:2/3):2/5=7/10
x:1/3=1/2+1/3
x:1/3=5/6
x =5/6.1/3
x =5/18
(x:2/3):2/5=7/10
x:2/3 =7/10.2/5
x:2/3 =7/25
x:2/3 =7/25.2/3
x:2/3 =14/75
Tìm x:
x(x-1)(x+3)-x^2(x+3)=-4
\(\Leftrightarrow x^3+2x^2-3x-x^3-3x^2=-4\)
\(\Leftrightarrow x^2+3x-4=0\)
=>(x+4)(x-1)=0
=>x=-4 hoặc x=1
Tìm x:x.(x-3)+x-3=0
tìm x:
x : 33 = \(\dfrac{9}{66}\) \(\dfrac{4}{5}\) x \(x\) = \(\dfrac{10}{11}\) :\(\dfrac{3}{4}\)
\(x:33=\dfrac{9}{66}\)
\(x=\dfrac{9}{66}\times33\)
\(x=\dfrac{9}{2}\)
\(\dfrac{4}{5}\times x=\dfrac{10}{11}:\dfrac{3}{4}\)
\(\dfrac{4}{5}\times x=\dfrac{40}{33}\)
\(x=\dfrac{40}{33}:\dfrac{4}{5}\)
\(x=\dfrac{50}{33}\)
#Đạt Đang Bận Thở
tìm x:
X:1/3=1/2+1/3 (X:2/3):2/5=7/10
Giúp cháuuuuuu!!!!
1) \(x:\dfrac{1}{3}=\dfrac{1}{2}+\dfrac{1}{3}\)
\(\Rightarrow3\times x=\dfrac{5}{6}\Rightarrow x=\dfrac{5}{18}\)
2) \(\left(x:\dfrac{2}{3}\right):\dfrac{2}{5}=\dfrac{7}{10}\)
\(\Rightarrow\dfrac{3}{2}\times x=\dfrac{7}{10}\times\dfrac{2}{5}=\dfrac{7}{25}\)
\(\Rightarrow x=\dfrac{7}{25}:\dfrac{3}{2}=\dfrac{14}{75}\)
X : 1/3 = 1/2 + 1/3
X = 5/18
( X : 2/3 ) : 2/5 = 7/10
X = 14/75
3.tìm x:x*0,25-72,5=22,2
tìm x:x*3+x*4+x=172
4.tổng 2 số là 68,2; thương 2 số là 4,5.tìm 2 số đó
5.hiệu 2 số là 0,6,thương 2 số cũng la 0,6.tìm 2 số đó
tìm X:
X x 3/4 + X/5 + 1.05 x X = 5.8
