x : 0,125 + x : 0,5 + x : 0,25 = x : 0,5 + 165
x : 8 + x : 2 + x : 4 = x : 2 + 165
x : x : 8 + x : 2 + x : 4 = 2 + 165
1 : 8 + x : 2 + x : 4 = 167
8 + x : [ 2 + 4 ] = 167
8 + x : 6 + 167
x : 6 = 167 - 8
x : 6 = 159
x = 159 : 6
x = 26.5
\(x:0,125+x:0,25-x:20\%-24=11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}-24=11\)
\(8\times x+4\times x-5\times x-24=11\)
\(7\times x=35\)
\(x=5\)
\(\text{x : 0 , 125 + x : 0 , 25 − x : 20 % − 24 = 11}\)
\(x : 0 , 125 + x : 0 , 25 − x : 0 , 2 − 24 = 11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}-24=11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}=24+11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}=35\)
\(\text{x ×}\dfrac{8}{1}+x\text{×}\dfrac{ }{ }+\dfrac{4}{1}-x\text{×}\dfrac{5}{1}=35\)
\(x × 8 + x × 4 − x × 5 = 35\)
\(x × ( 8 + 4 − 5 ) = 35\)
\(x × 7 = 35\)
\(x = 35 : 7\)
\(x = 5\)
x+x : 0,25 + x : 0,5 + x : 0,125 = 0,45
x + x .4 + x.2 + x.7 = 0,45
x . ( 1+4+2+8) = 0,45
x.15=0,45
x=0,45 :15
x=0,03
\(x\) + \(x\): 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
\(x\) = \(\dfrac{8}{3}\)
\(x+x:0,5+x:0,25+x:0,125=75\)
\(x+x\cdot2+x\cdot4+x\cdot8=75\)
\(x\cdot\left(1+2+4+8\right)=75\)
\(x\cdot15=75\\ x=75:15\\ x=5\)
x:1/4+x:1/8+x:1/2+1=0,90
x*4+x*8+x*2+x*1=0,90
x*(4+8+2+1)=0,90
x*15=0,90
x=0,06
