x:0,25+x nhan 11=24
x nhan 8,01-x:100=38
tìm x:x+x:0,25+x:0,5+x:0,125=40
\(x\) + \(x\): 0,25 + \(x\) : 0,5 + \(x\) : 0,125 = 40
\(x\) \(\times\) 1+ \(x\) \(\times\) 4 + \(x\) \(\times\) 2 + \(x\times\) 8 = 40
\(x\) \(\times\) ( 1 + 4 + 2 + 8) = 40
\(x\) \(\times\) 15 = 40
\(x\) = 40 : 15
\(x\) = \(\dfrac{8}{3}\)
tìm x:
x : 0,25 + x : 0,5 + x : 0,1 + x + x : 0,01 =23,4
\(x\times4+x\times2+x\times10+x+x\times100=23,4\)
\(x\times\left(4+2+10+100\right)=23,4\\ x\times116=23,4\\ x=\dfrac{23,4}{116}\approx0,2\)
tim x :
a) x: 0,25 + x . 11 = 24
b) x.8,01 -x : 100 = 38
c) 2,3 : 2,8 .x = 57,5
d) 0,16 : ( x : 3,5) = 2,8
nhanh minh se tick. minh hua
a) x:0,25+x.11=24
x.4+x.11 =24
x.(4+11) =24
x.15 =24
x=24:15
x=1,6
Trả lời :....................
x = 16.................................

x:0,125+x:0,25+x:0,2=190

tim x:x^5+x^4+x+1=0
giúp mik
\(x^5+x^4+x+1=0\)
\(\Leftrightarrow x+1=0\)
hay x=-1
tim x
x:x X 15 - 3,7 = 2,3
x:x*15-3,7=2,3
x:2*15-3,7=2,3
x:2*15=2,3+3,7
x:2*15=6
x:2=6:15
x*2=0,4
x=0,4:2
x=0,2
X : 0,25 + X x 11 = 24
⇒ X x 4 + X x 11 = 24
⇒ X x ( 4+11) = 24
⇒ X x 15 = 24
⇒ X = 24 : 15 = 1,6
X: 0,25 + X x 11 = 24
<=> X x 4 + X x 11= 24
<=> X x (4+11)= 24
<=> X x 15= 24
=> X= 24/15
\(x:0,25+x\times11=24\)
\(\Rightarrow x\times4+x\times11=24\)
\(\Rightarrow x\times\left(4+11\right)=24\)
\(\Rightarrow x\times15=24\)
\(\Rightarrow x=\dfrac{8}{5}\)
Vậy: \(x=\dfrac{8}{5}\)
