Học tốt!!!
X x 25,6 = 128 17,8 x X = 360,05 - 93,05 29,5 x [ X +10,25 ] = 376,125 748 : [ X - 31,72 ] = 13,6
CẢ CÁCH LÀM NHA YÊU NHIỀU HI HI
x * 25,6 = 128
x = 128 / 25,6 = 5
17,8 * x = 360,05 - 93,05
17,8 * x = 267
x = 267/17,8 = 15
29,5 * ( x + 10,25 ) = 376,125
x + 10,25 = 376,125/29,5
x + 10,25 = 12,75
x = 12,75 - 10,25 = 2,5
748 / ( x - 31,72 ) = 13,6
x - 31,72 = 748 - 13,6
x - 31,72 = 55
x = 55 + 31,72 = 86,72
a, 36 x X + 12,67 = 489,67 b, X x 326,63 + 245 x X = 429
c,X x 25,6 = 128 d, 17,8 x X = 360,05 – 93,05
e, 29,5 x ( X + 10,25 ) = 376, 125 f, 748 : ( X – 31, 72 ) = 13,6
a, 36 \(\times\) \(x\) + 12,67 = 489,67
36 \(\times\) \(x\) = 489,67 - 12,67
36 \(\times\) \(x\) = 477
\(x\) = \(\dfrac{477}{36}\)
\(x\) = 12,35
29,5*(x+10,25)=376,125
( các bạn nhớ giúp mik nhé)
mk di rui mk giai cho
bai nay de lam
thank nha
Tìm x :
a ) 36 * x + 12 , 67 = 489,67
b ) x * 326,63 = 247 ,37
c ) 29 , 5 * (x + 10,25) = 376 , 125
d ) 748 : ( x - 31,72 ) = 13,6
giúp mình nha !!!
a) \(36x+12,67=489,67\)
\(\Rightarrow36x=489,67-12,67\)
\(\Rightarrow36x=477\)
\(\Rightarrow x=477:36\)
\(\Rightarrow x=13,25\)
Vậy \(x=13,25\)
b) \(x.326,63=247,37\)
\(\Rightarrow x=247,37:326,63\)
\(\Rightarrow x=0,7573401096\)
Vậy \(x=0,7573401096\)
c) \(29,5\left(x+10,25\right)=376,125\)
\(\Rightarrow x+10,25=376,125:29,5\)
\(\Rightarrow x+10,25=12,75\)
\(\Rightarrow x=12,75-10,25\)
\(\Rightarrow x=2,5\)
Vậy \(x=2,5\)
d) \(748:\left(x+31,72\right)=13,6\)
\(\Rightarrow x+31,72=748:13,6\)
\(\Rightarrow x+31,72=55\)
\(\Rightarrow x=55-31,72\)
\(\Rightarrow x=23,28\)
Vậy \(x=23,28\)
748; x-31,72=13,6
748: x-31,72=13,6
748: x=13,6+31,72
748: x=45,32
x=748:45,32=16,50485............
ta có:
748 : X - 31,72 = 13,6
748 : X = 13,6 + 31,72
748 : X = 45,32
X = 748 : 45,32
X = bao nhiêu tự tính
tk cho mk nha
748:(x-31,72)=13,6
( giúp mik nha)
748:(x-31,72)=13,6
x-31,72=748:13,6
x-31,72=55
x=55+31,72
x=86,72
vậy x=86,72
k mk nha
748:(x-31,72)=13,6
x-31,72=748:13,6
x-31,72=55
x=55+31,72
x=82,72
Tìm X
a) X x 1,5 - 5,61 = 6,45 b) 89 : X + 51,5 : X = 62,5 c) 748 : ( X - 31,72 ) = 13,6
\(x\cdot1,5-5,61=6,45\)
\(x\cdot1,5=12,06\)
\(x=8,04\)
\(89:x+51,5:x=62,5\)
\(\left(89+51,5\right):x=62,5\)
\(140,5:x=62,5\)
\(x=2,248\)
\(748:\left(x-31,72\right)=13,6\)
\(x-31,72=55\)
\(x=86,72\)
