tìm x
[ 0,(37) + 0 + 0,(62) ] . x = 10
0,(12) : 1,(6) = x : 0,(4)
giúp mình với nhé
1} Tính
A] 10(3) +0,(4) -8(6)
B] [ 12,3(1) -2,3(6) ] :4,(21)
2, tìm x biết
A] [ 0, (37 ) +0,(62) ] .x=10\
B] 0,(12) 1,(6) =x:0,(4)
Giups mình nhé thanks nhìu
Tìm x, biết:
a) 0 , ( 37 ) + 0 , ( 62 ) . x = 10
b) 0 , ( 12 ) : 1 , ( 6 ) = x : 0 , ( 4 )
c) 0 , ( 37 ) . x = 1
d) 0 , ( 26 ) . x = 1 , 2 ( 31 )
tìm x biết: a) [0,(37)+0,(62)]x=10
b)0,(12):1,(6)=x:0.(4)
tìm x biết: a) [0,(37)+0,(62)]x=10
b)0,(12):1,(6)=x:0.(4)
tìm x biết: a) [0,(37)+0,(62)]x=10
b)0,(12):1,(6)=x:0.(4)
tìm x biết: a) [0,(37)+0,(62)]x=10
b)0,(12):1,(6)=x:0.(4)
a: \(\Leftrightarrow x\cdot\left(\dfrac{37}{99}+\dfrac{62}{99}\right)=10\)
=>x=10
b: \(\Leftrightarrow x:\dfrac{4}{9}=\dfrac{4}{33}:\dfrac{5}{3}=\dfrac{4}{33}\cdot\dfrac{3}{5}=\dfrac{4}{55}\)
\(\Leftrightarrow x=\dfrac{16}{495}\)
Tìm x,biết
a) [0,(37) + 0,(62)] .x = 10
b) 0,(12) : 1,(6) = x : 0,(4)
Tính:
a) [0,(37) + 0,(62)].x = 10
b) 0,(12) : 1,(6) = x : 0,(4)
c) 0 , 3 + 0 , 384615 + 3 13 x 0 , 0 3 + 13 = 50 85
Bài 1: Tìm x
a, \(\left[0,\left(37\right)+0,\left(62\right)\right].x=10\)
b,\(0,\left(12\right):1,\left(6\right)=x:0,\left(4\right)\)
a) \(\left[0,\left(37\right)+0,\left(62\right)\right]\cdot x=10\)
=> \(\left[\frac{37}{99}+\frac{62}{99}\right]\cdot x=10\)
=> \(1\cdot x=10\Rightarrow x=10\)
b) \(\frac{0,\left(12\right)}{1,\left(6\right)}=\frac{\frac{12}{99}}{\frac{5}{3}}=\frac{12}{99}\cdot\frac{3}{5}=\frac{4}{55}\)
=> \(\frac{4}{55}=x:0,\left(4\right)\)
=> \(\frac{4}{55}=x:\frac{4}{9}\)
=> \(x:\frac{4}{9}=\frac{4}{55}\)
=> \(x=\frac{4}{55}\cdot\frac{4}{9}=\frac{16}{495}\)
