Tìm X:
0,12 x X = 6
Tìm \(x\):
a) 0,12 \(\times\) \(x\) \(=\) 6; b) \(x\) \(:\) 2,5 \(=\) 4;
c) 5,6 \(:\) \(x\) \(=\) 4; d) \(x\) \(\times\) 0,1 \(=\) \(\dfrac{2}{5}\).
a) PT \(\Leftrightarrow x=\dfrac{6}{0,12}=50\)
Vậy \(x=50\)
b) PT \(\Leftrightarrow x=4\cdot2,5=10\)
Vậy \(x=10\)
c) PT \(\Leftrightarrow x=\dfrac{5,6}{4}=1,4\)
Vậy \(x=1,4\)
d) \(\Leftrightarrow x=\dfrac{\dfrac{2}{5}}{0,1}=4\)
Vậy \(x=4\)
a) \(0,12\times x=6\)
\(x=\dfrac{6}{0,12}\)
\(x=50\).

tìm x biết :
x +1,75:0,12=1+2-3+4-5+6-........+118-119+120
tìm X biết:
a) X + 3,6 = 4,26 + 7,52 b) 0,12 * X = 6
a)x+3,6=11,78
x=11,78-3,6=8,18
b)0,12*x=6
x=6:0,12=50
a) x + 3.6 = 4.26 + 7.52 b) 0.12 * x = 6
x + 3.6 = 11.78 x = 6 : 0.12
x = 11.78 - 3.6 x = 50
x = 8.18
tìm x: 0,9 < x < 0,12
0,9 < x < 0,12
x = 0,10 ; 0,11
nếu sai thì bn thông cảm ạ
(x + 2) + (2 * x + 4) + (3 * x + 6)= 400*0,12 giúp em với😗
(\(x+2\)) + ( 2\(\times\) \(x\) + 4) + ( 3 \(\times\) \(x\) + 6) = 400 \(\times\)0,12
\(x\) + 2 + 2 \(\times\) \(x\) + 4 + 3 \(\times\) \(x\) + 6 = 48
\(x\) \(\times\) ( 1 + 2 + 3) + ( 2 + 4 + 6) = 48
\(x\) \(\times\) 6 + 12 = 48
\(x\) \(\times\) 6 = 48 - 12
\(x\) \(\times\) 6 = 36
\(x\) = 36 : 6
\(x\) = 6
