Bài làm:
\(10,035=10\frac{7}{200}=10\frac{35}{1000}\)
\(\Rightarrow\)Chọn \(C\)
![](https://rs.olm.vn/images/avt/0.png?1311)
a, 35 - \(x\) < 35 - 5
35 - \(x\) < 30
\(x\) < 35 - 30
\(x\) < 5
\(x\) = 1; 2; 3; 4; 5
b, \(x\) - 10 < 35 - 10
\(x\) - 10 < 15
\(x\) < 15 + 10
\(x\) < 25
\(x\) = 0; 1; 2; 3; 4; 5; ....;24
c, \(x\) - 10 < 45
\(x\) < 45 + 10
\(x\) < 55
\(x\) = 0; 1; 2; 3; 4;...;54

câu 1: A=-10x(2+7)
=-10x9
=-90
câu 2 B=-35x(2+8)
=-35x10
=-350
\(A=7.\left(-10\right)+\left(-10\right).2\)
\(=-10\left(7+2\right)\)
\(=-10.9\)
\(=-90\)

19/10 - (2/35 - 1/10 ) - 33/35
= 19/10 - 2/35 + 1/10 - 33/35
= (19/10 + 1/10) - (2/35 +33/35)
= 2 - 1
= 1
\(\frac{19}{10}-\left(\frac{2}{35}-\frac{1}{10}\right)-\frac{33}{35}\)
\(=\frac{19}{10}-\frac{2}{35}+\frac{1}{10}-\frac{33}{35}\)
\(=\left(\frac{19}{10}+\frac{1}{10}\right)-\left(\frac{2}{35}-\frac{33}{35}\right)\)
\(=2-\left(-1\right)=3\)

Ta có: 35/7=5
1/10= 0,1
Xếp theo thứ tự tăng dần là: 0,1 ; 5 ; 34,99 ; 35
Hay: 1/10 ; 35/7 ; 34,99 ; 35

\(32.\left(10-35\right)-35.\left(18-32\right)\)
\(=32.-25-35.-14\)
\(=32.\left(-25--14\right)\)
\(=32.-11\)
\(=-352\)
= 45 nha
10 + 35 = 45
