giải giúp mình với 

17464 - 17464 : 74 - 74 x 158

= 158 x ( 17464 - 17464 ) : ( 74 - 74 )

= 158 x 0 : 0

= 0 x 0

= 0

A= 5563

B= 11859

C=0

D =167802

         học tốt

kb rùi đấy bạn đồng ý đi

a: \(17464-17464:74-74\cdot158\)

\(=17464\cdot\left(1-\dfrac{1}{74}\right)-74\cdot158\)

\(=17464\cdot\dfrac{73}{74}-74\cdot158\)

\(=5536\)

5536 nhé bạn

thấy đúng thì tim nhé

=5536

tính máy tính

a, 5536

Còn lại lên tra gu gồ là ra bn nhớ 

a) 

x – 8 + 32 = 68

x – 8 = 68 – 32 

x – 8 = 36

x = 36 + 8

x = 44

b) 

x + 8 + 32 = 68

x + 8 = 68 – 32

x + 8 = 36

x = 36 – 8

x = 28

c) 

98 – x + 34 = 43

98 – x = 43 – 34

98 – x = 9

x = 98 – 9 

x = 89 

d) 

98 + x – 34 = 43

98 + x  = 43 + 34 

98 + x = 77

x = 98 – 77 

x = 21

tick cho mink nhé!

C. 51; 68 nha bn

\(B\left(17\right)\in\left\{17;34;51;68;85;...\right\}\)

Mà B(17) >50, <70

\(\Rightarrow B\left(17\right)\in\left\{51;68\right\}\)

Chọn C

x - 12 x 34 : 1 = 68

x - 408 = 68

x = 68 + 408 = 476

X-12 x 34 =68

X-12 = 68 : 34

x-12=2

x=12-2

x=10

476

x + 34 = 68

x         = 68 - 34

x         = 34

x= 68- 34

 x= 34

X + 34 = 68

X = 68 - 34

X = 34
