4,85-( \(3\frac{1}{8}\)+1,105)<x<9,1-(6,85- \(2\frac{3}{4}\)) voi X\(\in Z\)
Tìm x
\(4,85-\left(3\frac{1}{8}+1,105\right)< x< 9,1-\left(6,85-2\frac{3}{4}\right);x\varepsilon Z\)
\(b,4,85-\left(3\frac{1}{8}+1,105\right)
\(=4,85-\left(\frac{25}{8}+1,105\right)4,85-\left(3,125+1,105\right)=4,85-4,23=0,62\)
\(3,85-(3\frac{1}{8}+1,105)< x< 6,1-(4,85-2\frac{3}{4})\)
Tìm X, ai xong trước mình tick nha, nhớ cả cách giải chi tiết nữa
\(3,85-\left(3\frac{1}{8}+1,105\right)< x< 6,1-\left(4,85-2\frac{3}{4}\right)\)
\(3,85-\left(3,125+1,105\right)< x< 6,1-\left(4,85-2,75\right)\)
\(3,85-4,23< x< 6,1-2,1\)
\(-0,38< x< 4\)
\(\Rightarrow x\in\left\{-0,37;-0,36;...;2;3\right\}\)

4,85-(3 1/8+1,105)<x<9,1-(6,85-2 3/4) x thuộc z
đebài:tìm x
Tìm số nguyên x , biết :
a) \(3\frac{2}{3}.\left(\frac{1}{5}-\frac{1}{2}\right)< x< \frac{3}{11}.\left(\frac{1}{5}+\frac{2}{3}-\frac{1}{2}\right)\)
b) \(4,85-\left(3\frac{1}{8}+1,105\right)< x< 91-\left(6,85-2\frac{3}{4}\right)\)
Tìm số nguyên x biết:
a,x/20=7/15
b,3/2/3.(1/5-1/2)<hoặc=3/11.(1/5+2/3-1/2)
c,4,85-(3/1/8+1,105)<x<9,1-(6,85-2/3/4)
4,85 - ( 25/8 + 1,105)< x < 9,1- (6,85 - 11/4) với x thuộc Z
do 4,85-(25/8+1,105)=0,62< x < 9,1-(6,85-11/4)=5
=>x thuộc khoảng từ{1,2,3,4}
Tìm x biết:
a)\(3\frac{2}{3}.\left(\frac{1}{5}-\frac{1}{2}\right)\)bé hơn hoặc bằng x bé hơn hoặc bằng \(\frac{3}{11}.\left(\frac{1}{5}+\frac{2}{3}-\frac{1}{2}\right)\)
b) \(4,85-\left(3\frac{1}{8}+1,105\right)< x< 9,1-\left(6,85-2\frac{3}{4}\right)\)
