Ta có : \(\frac{-15}{5}\le x< \frac{22}{11}\)
\(\Rightarrow-3\le x< 2\)
Vì \(x\in Z\Rightarrow x\in\left\{-3;-2;-1;0;1\right\}\)
Tìm số nguyên x
a) \(\frac{1}{3}+\frac{-2}{5}+\frac{1}{6}+\frac{-1}{5}\le x< \frac{-3}{4}+\frac{2}{7}+\frac{-1}{4}+\frac{3}{5}+\frac{5}{7}\)
b)\(\frac{5}{17}+\frac{-9}{4}+\frac{-26}{31}+\frac{12}{17}+\frac{-11}{31}< \frac{x}{9}\le\frac{-3}{7}+\frac{7}{15}+\frac{4}{-7}+\frac{8}{15}\)
\(\frac{22}{3}\left(\frac{1}{6}-\frac{1}{2}\right)\) \(\le\) X \(\le\) \(\frac{3}{4}\left(\frac{1}{6}-\frac{1}{5}-\frac{1}{15}\right)\)
Bài 1:
Số gtrij nguyên của x thỏa mãn: \(\frac{-19}{6}+\frac{-15}{2}+\frac{11}{3}
Cho \(A=\frac{5}{17}+\frac{-4}{9}-\frac{20}{31}+\frac{12}{17}-\frac{11}{31}\)
\(B=\frac{-3}{7}+\frac{7}{15}+\frac{-4}{7}+\frac{8}{15}-\frac{-2}{3}\)
Tính số nguyên x sao cho \(A< \frac{x}{9}\le B\)
Tìm x:
\(-\frac{5}{17}+\frac{3}{17}\le\frac{x}{17}\le\frac{13}{17}+-\frac{11}{17}\)
\(\frac{5}{6}+-\frac{7}{8}\le\frac{x}{24}\le-\frac{5}{12}+\frac{5}{8}\)
\(\frac{8}{17}+\frac{5}{17}< \frac{x}{17}< \frac{6}{17}+\frac{9}{17}\)
\(-\frac{6}{7}+\frac{3}{35}< \frac{x}{35}\le-\frac{2}{5}+\frac{3}{7}\)
ai nhanh và đúng mk tick
tính giá trị của các biểu thức
B= x +\(\frac{0,2-0,375+\frac{5}{11}}{-0,3+\frac{9}{16}-\frac{15}{22}}\) với x = \(\frac{1}{3}\)
- Bài 1 :
a, \(\left(\frac{4}{5}+\frac{2}{3}\right):\frac{1}{5}-1,4\times\left(\frac{-5}{7}\right)^2\)
- Bài 2
a, \(\frac{3}{2}-|\frac{1}{2}x-\frac{1}{3}|=\frac{1}{2}\)
b,Tìm \(x\inℤ\)biết \(0,6-160\%< x\le3\frac{2}{3}:\frac{22}{18}\)
- LM hết tick 3 tick ^-^
Tìm \(x\in Z\) \(3\frac{2}{3}.\left(\frac{1}{5}-\frac{1}{2}\right)\le x\le\frac{3}{11}.\left(\frac{1}{5}+\frac{2}{3}-\frac{1}{2}\right)\)
Giúp với
\(a,3\frac{2}{3}\left(\frac{1}{5}-\frac{1}{2}\right)\le x\le\frac{3}{11}\left(\frac{1}{5}+\frac{2}{3}-\frac{1}{2}\right)\)
