1) Tìm x:
(1,16-x).5,25/(10va5/9 - 7va1/4).2 va 2/17= 75%
Tìm x
\(\frac{\left(1,16-x\right).5,25}{\left(10\frac{5}{9}-7\frac{1}{4}\right).2\frac{2}{17}}=75\%\)
tìm x biết :
(1,16-x).5,25/(10va5/9 - 7va 1/4).2 va 2/17= 75%
Tìm x :
\(\frac{(1,16-x).5,25}{(10\frac{5}{9}-7\frac{1}{4}).2\frac{2}{17}}\)= 75 phần trăm .
\(\frac{\left(1,16-x\right).5,25}{\left(10\frac{5}{9}-7\frac{1}{4}\right).2\frac{2}{17}}=75\%\) <=> \(\frac{6,09-5,25x}{\left(\frac{95}{9}-\frac{29}{4}\right).\frac{36}{17}}=\frac{3}{4}\)<=> \(\frac{6,09-5,25x}{\frac{119}{36}.\frac{36}{17}}=\frac{3}{4}\)
<=> \(\frac{6,09-5,25x}{7}=\frac{3}{4}\)<=> 4(6,09-5,25x)=21 <=> 24,36-21x=21
=> 21x=3,36 => x=3,36:21 => x=0,16
Đáp số: x=0,16
tìm x biết
a)x+30%x = -1,3
b) \(\frac{\left(1,16-x\right).5,25}{\left(10\frac{5}{9}-7\frac{1}{4}\right).2\frac{2}{17}}=75\%\)
x + 30% x = - 1,3
x ( 100% + 30% ) = - 1,3
x . 130% = - 1,3
x = - 1,3 : 130%
x = - 1,69
Tìm x biết:
