x + 25 = 53
x - 56 = 28
56 - x = 17
22 - x = 16
Tìm x
\(\dfrac{25-x}{56}\) = \(\dfrac{6}{16}\)
`(25-x)/56 = 6/16`
`=> (25-x)xx16= 56xx6`
`=> (25-x)xx16= 336`
`=> 25-x=336:16`
`=> 25-x=21`
`=>x=25-21`
`=>x=4`
`(25 - x)/56 = 6/16`
`=> (25 - x)/56 = 3/8`
`=> (25 - x)/56 = 21/56`
`=> 25 -x = 21`
`=> x = 25 - 21`
`=> x = 4`
Vậy `x = 4`
Tìm x:
25 - x/56 = 6/16
\(x=\left(25-\dfrac{6}{16}\right).56=1379\)
25-x/56=6/16
tìm x
Ta có :25-x/56=6/16 <=>25-x/56=3/8
Gọi 25-x là y =>y/56=3/8
=>y=56 nhân 3 chia 8 vậy y =21
tương đương 25-x=21
x=25-21=4
Vậy x=4 thì 25-x/56=6/16

Vào trang này đi. kết quả đó
25 - x : 56 = 6 : 16
x : 56 = 6/16 + 25
x : 56 = 25 , 375
x= 25,375 x 56
x=1421 .
25-x/56=6/16
\(25-\frac{x}{56}=\frac{6}{16}\)
\(\frac{x}{56}=25-\frac{6}{16}\)
\(\frac{x}{56}=24,625\)
\(x=24,625\times56\)
\(x=1379\)
25-x/56=6/16
x/56=25-6/16
x/56=24.526
x=24.625x56
x=1379
vay =1379
25-x/56=6/16
25-x/56=6/16
x/56=25-6/16
x/56=24\(\frac{5}{8}\)
x/56=24\(\frac{35}{56}\)
x/56=\(\frac{24\times56+35}{56}\)
x/56=\(\frac{1379}{56}\)
Vậy số cần tìm là:\(\frac{1379}{56}\)
25-\(\frac{x}{56}=\frac{6}{16}\)
\(\frac{x}{56}=25-\frac{6}{16}\)
\(\frac{x}{56}=\frac{197}{8}\)
\(\frac{x}{56}=\frac{1379}{56}\)
=>x=1379
\(\frac{25-x}{56}=\frac{6}{16}\)
Tìm x
\(\frac{25-x}{56}=\frac{6}{16}\)
\(\frac{25-x}{56}=\frac{3}{8}\)
\(\frac{25-x}{56}=\frac{21}{56}\)
\(\Rightarrow25-x=21\)
\(\Rightarrow x=25-21\)
\(\Rightarrow x=4\)
Vậy x=4
=>(25-x)16=6x56=280
25-x=17.5
x=7.5=15/2
vậy x=15/2
ta giản ước : 6/16 = 3/8 như vậy, ta có :
\(\frac{25-x}{56}=\frac{3}{8}\)
quy đồng 2 phân số cho nhau : ( mẫu số chung ) = 56
ta có : 56 : 8 = 7
\(\frac{3x7}{8x7}=\frac{21}{56}\)
bây giờ, bài toán sẽ như sau :
\(\frac{25-x}{56}=\frac{21}{56}\)
vậy, x = 25 - 21 = 4
k mk nha
chúc bạn học giỏi
Rút gọn
\(\frac{x^3-53x+88}{\left(x-1\right)\left(x-3\right)\left(x-5\right)\left(x-7\right)+16}\)
tim x
\(\frac{25-x}{56}=\frac{6}{16}\)
25 - x / 56 = 6/16
( 25 - x ) : 56 = 6/16
25 - x = 6/16 x 56
25 - x = 21
x = 25 - 21
x = 4
\(\frac{25-x}{56}=\frac{6}{16}\)
\(\frac{x}{56}=25-\frac{6}{16}\)
\(\frac{x}{56}=24\frac{5}{8}\)
\(\frac{x}{56}=24\frac{35}{56}\)
\(\frac{x}{56}=\frac{24\cdot56+35}{56}\)
\(\frac{x}{56}=\frac{1379}{56}\)
Vậy số cần tìm là \(1379\)
25-X= 6x56:16
25-X=21
X=25-21
X=4
K cho mình nhé, ai có facebook thì kb với mình luôn nha <3
Tìm x, biết:
a ) x = 5 6 + − 2 3 ; b ) x = − 4 3 + − 7 5 ; c ) x = 3 4 + − 1 6 + 2 5 ; d ) x 12 = 3 4 + − 7 6 ; e ) x 6 = 3 2 + − 7 15 ; f ) 11 8 + 13 10 = 107 x
a ) x = 1 6 ; b ) x = − 41 15 ; c ) x = 59 60 ;
d ) x 12 = − 5 12 = > x = − 5 ; e ) x 6 = 31 30 = > x = 31 5
