Bài 1: Tìm x
X x 3,7 + X x 1,3 = 2,5
X x 8,01 -x : 100 = 38
giúp mình với
x x 8,01 - x : 100 = 38
x x 8,01 – x :100 = 38
x x 8,01 - x : 0,01=38
x x (8,01 - 0,01) = 38
x x 8 = 38
x = 38 : 8
x=4,75
x x 8,01 - x : 100 = 38
x x 8,01 - x x 0,01 = 38
x x (8,01 - 0,01) = 38
x x 8 = 38
x = 38 : 8
x = 4,75
X x 8,01 – x : 100 – 38
Giups minh voi huhu
X x 8,01 - X : 100=38
X x 8,01 - X : 100 = 38
X x 8,01 - X x 0,01 = 38
X x (8,01 - 0,01 ) = 38
X x 8 = 38
X = 38 :8
X = 4,75
X*8,01-X: 100=38
x*8,01-x:100=38
x*8,01-x*1/100=38
x*(801/100-1/100)=38
x*800/100=38
x*8=38
x = 38:8
x =4,75
k cho mình nha
X x 8,01 - X : 100 = 38 giup minh
X x 8,01 - X :1/100=38
X x ( 8,01 - 0.01 ) = 38
X x 8 = 38
X = 4.75
tìm X :
X : 0,25 + X x 11 = 24
X x 8,01 - X : 100=38
a)
X : 0,25 + X x 11 = 24
<=> X : 1/4 + X x 11 = 24
<=> X x 4 + X x 11 = 24
=> X x ( 4 + 11 ) = 24
=> X x 15 = 24
=> X = 1,6
b)
X x 8,01 - X : 100 = 38
<=> X x 8,01 - X : 1/100 = 38
<=> X x 8,01 - X x 0,01 = 38
=> X x ( 8,01 - 0,01 ) = 38
=> X x 8 = 38
=> x = 4,75
Tìm x a) x: 0,25+ x . 11=24
b) x. 8,01 - x: 100= 38
a, x :0,25+x.11=24
x:1/4+x.11=24
x.4+x.11=24
x.(4+11)=24
x.15=24
x =24:15
x=1,6
b, x.8,01-x:100=38
x.801/100-x.1/100=38
x.(801/100-1/100)=38
x.8=34
x=34:8
x=4,25
x : 0,25 + x × 11 = 24
2,3 : ( 2,8 : x ) = 57,5
x × 8,01 - x : 100 = 38
ta co lick 18 tank joke phuong kakasi va sat thu va con nhieu con khac dang muon ban lick co ai mua khong
X:0,25+X x 11=24
X x 4+ X x 11=24
X x 15=24
X =24:15
X=...
2,3 : ( 2,8 : x ) = 57,5
x × 8,01 - x : 100 = 38
\(2,3:\left(2,8:x\right)=57,5\)
\(2,8:x=\frac{2,3}{57,5}\)
\(2,8:x=0,04\)
\(x=\frac{2,8}{0,04}\)
\(x=70\)
vậy \(x=70\)
\(8,01x-\frac{1}{100}x=38\)
\(8x=38\)
\(x=4,75\)
vậy \(x=4,75\)
