`x xx11<770`
`x xx 11<770`
Ta có : `x xx 11<770`
`x=770:11`
`x=70`
Mà để cho `x xx 11<770`
`=>x<70`
Mà `x` là giá trị lớn nhất.
`=>69`
\(x\times11< 770\)
\(x=770:11\)
\(x=70\)
Mà theo đề ta có:
\(x\times11< 770\)
\(nên\) \(x< 70\)
\(=>x\in\left\{1,2,3....69\right\}\)
X :0.25 + X x 11 = 24
X : 0.25 + X x 11 = 24
x : 0,125 + x : 0.25 - x : 20% - 24 = 11
\(x:0,125+x:0,25-x:20\%-24=11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}-24=11\)
\(8\times x+4\times x-5\times x-24=11\)
\(7\times x=35\)
\(x=5\)
\(\text{x : 0 , 125 + x : 0 , 25 − x : 20 % − 24 = 11}\)
\(x : 0 , 125 + x : 0 , 25 − x : 0 , 2 − 24 = 11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}-24=11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}=24+11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}=35\)
\(\text{x ×}\dfrac{8}{1}+x\text{×}\dfrac{ }{ }+\dfrac{4}{1}-x\text{×}\dfrac{5}{1}=35\)
\(x × 8 + x × 4 − x × 5 = 35\)
\(x × ( 8 + 4 − 5 ) = 35\)
\(x × 7 = 35\)
\(x = 35 : 7\)
\(x = 5\)
X : 0.25+X NHAN11=24
x : 0,25 + x nhân 11 = 24
x nhân 4 + x nhân 11 = 24
x nhân ( 4 + 11 ) = 24
x nhân 15 = 24
x = 24 ; 15
x = 1,6
vậy x = 1,6 nha
X:0,25+Xx11=24
Xx4+Xx11=24
Xx(4+11)=24
Xx15=24
X=24:15
X=1,6
\(\frac{X.11}{0,25+X}\) = 24 <=> 11.X = 6 + 24.X <=> -13.X = 6 => X = - 6/13
X : 0.25 + X nhan 11=24
X : 0.25 +X nhân 11 =24
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 = 1,6
Chúc bạn học tốt.
