X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
X x (100 + 200 + 300 + 400 + 500 + 512) = 2012
X x 2012 = 2012
X = 2012 : 2012
X = 1
thanks.
X * 100 + X* 200 + X * 300 + X * 400 + X * 500 + X * 512 = 2012
X * (100 + 200 + 300 + 400 + 500 + 512) = 2012
X * 2012 = 2012
X = 2012 : 2012
X = 1
Vậy X bằng 1

a, X:6x4=1,248 =>X=1,248:4x6=1,872
b,7xX-2xX=1,85 =>5xX=1,85 =>X=1,85:5=0,37
c,Xx1000=499,7 =>X=499,7:1000=0,4997

x.x-\(\frac{1}{6}\)=\(\frac{5}{18}\)
x2-\(\frac{1}{6}\)=\(\frac{5}{18}\)
x2=\(\frac{5}{18}\)+\(\frac{1}{6}\)
x2=\(\frac{8}{18}\)
tk mk nha

a: \(=167\cdot\dfrac{67}{1000}+167\cdot\dfrac{33}{1000}=167\cdot\dfrac{1}{10}=\dfrac{167}{10}\)

b) ( x + 1 ) + ( x +2 ) + ( x + 3 ) + ..... + ( x + 99 ) =6130
( x + x + ... + x ) + ( 1 + 2 + 3 +... + 99 ) =6130
99 × x + 4950 =6130
99 × x = 6130 - 4950
99 × x = 1175

X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
X = 2012 : ( 100 + 200 + 300 + 400 + 500 + 512)
X = 2012 : 2012
X = 1
Nhớ k mình nhé
X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
X x ( 100 + 200 + 300 + 400 + 500 + 512 ) = 2012
X x 2012 = 2012
X = 2012 : 2012
X = 1
