a)\(x:\frac{9}{22}=44\)                                    b)\(x:\frac{5}{11}=33\)                           c)\(x:\frac{4}{33}=22\)

 \(x\)     \(=44\times\frac{9}{22}\)                        \(x\)       \(=33\times\frac{5}{11}\)                \(x\)       \(=22\times\frac{4}{33}\)    

   \(x\)      \(=18\)                                    \(x\)         \(=15\)                          \(x\)        \(=\frac{8}{3}\)

A) X : 9/22 = 44

              X=44x9/22

              X=18

B) X : 5/11 = 33

              X=33x5/11

              X=15

C) X : 4/33 = 22

              X=22x4/33

              X=8/3

\(x:\frac{9}{22}=44\)

\(x=44X\frac{9}{22}\)

\(x=18\)

vậy X = 18

\(x:\frac{5}{11}=33\)

\(x=33X\frac{5}{11}\)

\(x=15\)

vậy X = 15

\(x:\frac{4}{33}=22\)

\(x=22X\frac{4}{33}\)

\(x=\frac{8}{3}\)

vậy X = \(\frac{8}{3}\)

(45+75)*66+(75+45)*34

=(45+75)*(66+34)

=120*100

=405

Ta có :

a, (45 + 75) x 66 + (75 + 45) x 34

=  (45 + 75) x (66 + 34)

=   120  x 100

=  12000

11 + 22 + 33 + 44 + 55 + 66 + 77 + 88 + 99 : 11

= 33 + 77 + 121 + 165 + 9

= 405

\(11+22+33+44+55+66+77+88+99:11\)

\(\left(11+99\right)+\left(22+88\right)+\left(33+77\right)+\left(44+66\right)+55:11\)

a/ x + 22 - 33 = 44 + 11

 x +22 - 33 = 55

x + 22 = 33 + 55

x + 22 = 88

x = 88 - 22

x = 66

b/  x - 10 + 20 = 10 + 10

    x - 10 + 20 = 20

   x - 10 = 20 - 20

  x - 10 = 0

x = 0 + 10

x = 10

nhanh nha, ai k mk, mk k lai

a) x + 22= 44 + 11 + 33

x+ 22= 88

x= 88-22= 66

b) x-10= 10+10-20

x-10=0

x=10

\(\frac{x+11}{115}+\frac{x+22}{104}=\frac{x+33}{93}+\frac{x+44}{82}\)

\(\Leftrightarrow\frac{1+\left(x+11\right)}{115}+\frac{1+\left(x+22\right)}{104}=\frac{1+\left(x+33\right)}{93}+\frac{1+\left(x+44\right)}{82}\)

\(\Leftrightarrow\frac{x+126}{115}+\frac{x+126}{104}=\frac{x+126}{93}+\frac{x+126}{82}\)

\(\Leftrightarrow\left(x+126\right).\left(\frac{1}{115}+\frac{1}{104}+\frac{1}{93}+\frac{1}{82}\right)=0\)

\(\Leftrightarrow x+126=6\Leftrightarrow x=-126\)vì\(\frac{1}{115}+\frac{1}{104}+\frac{1}{93}+\frac{1}{82}\ne0\)

vậy x=-126
