\(\Leftrightarrow x-\dfrac{1}{4}=\dfrac{20}{27}\)
hay x=20/27+1/4=107/108
\(\Leftrightarrow x-\dfrac{1}{4}=\dfrac{20}{27}\)
hay x=20/27+1/4=107/108
x-1phần 4=5 phần 6×4 phần 9
x phần 126 = -5 phần 9 nhân 4 phần 7
/x+1/-5=0
x phần 3=6 phần -9
help me!!
ae giúp mik
3x phần 4 -6 phần 27=2÷(1 phần 3- 2 phần 5
x-1/4=5/3×4/9
x-1/4=5/3×4/9
\(A.\dfrac{-15}{28}x\dfrac{7}{25}\\ B.\dfrac{-5}{14}x\dfrac{7}{-3}\\ C.\dfrac{-1}{5}-\dfrac{7}{15}x\dfrac{9}{35}\\ D.\dfrac{-3}{4}-(\dfrac{-1}{2})^2\\ E.\dfrac{-4}{5}-\dfrac{-4}{5}x\dfrac{15}{16}\\F.(\dfrac{3}{4}+\dfrac{-7}{2})x(\dfrac{2}{11}+\dfrac{12}{22})\)
1+2+3+4+5+6+7+8+9+0+1+2+3+4+5+6+7+8+9+9+8+7+6+5+4+3+2+1+1+34+4+6+7+8+97+6+4+3+32+4+57+7+8+8+6+65+4+3+3+46+7+8+7+64+3+3+5+68+8+6+3+3+5+78+8+6+54+5+7+8+852+3+5+89+8+5+45+7×9×9×9×9×9×9×9×9×9×9×9×8×8×7×9×9×7×7×87×7×8×7×7×8×7×7×8
Tìm \(x\), biết :
a) \(x-\dfrac{1}{4}=\dfrac{5}{8}.\dfrac{2}{3}\)
b) \(\dfrac{x}{126}=\dfrac{-5}{9}.\dfrac{4}{7}\)
