2 x 30 - X - X=52
30% x X + X = 52
tim X biet : 30% x X + X = 52
Ta có: 30%xX+X=52
nên 130%xX=52
X=52:130%=40
Vậy X= 40
40 bạn ơi
30% x X + X = 52
30 % x X + X x 100% = 52
130 % x X = 52
X = 52 x 100 / 130
X = 40
nhớ k cho mình nhé
30% x X + X =52
X + X = 52 : 30%
2X= 520/3
X = 520/3 :2
X = 520/3 x1/2
X = 260/3
Tim X biet : 30% x X +X =52
tìm x thuộc Z
a)30(x+2)-6(x-5)-24.x=100
b)52-/x/=80
c)/7x+1/+(-4)^2=(-6)^2
d)(-42)-3./x-5/=(-3)^3
e)34+(21-x)=(3747-30)+(-3747)
30% * x + x= 52
\(30\%\cdot x+x=52\)
\(\left(\frac{3}{10}+1\right)x=52\)
\(\frac{13}{10}x=52\)
\(x=40\)
\(\text{Ta có: 30% * x + x= 52 }\)
\(\Rightarrow\frac{3}{10}x+x=52\)
\(\Rightarrow\left(\frac{3}{10}+1\right)x=52\)
\(\Rightarrow\frac{13}{10}x=52\)
Đổi 30% = 3/10
=> 3/10 * x + x = 52
=> x * ( 3/10 + 1 ) = 52
=> x * 13/10 = 52
=> x = 52 : 13/10
=> x = 10
Vậy x = 40
30%×X+X = 52
30% x X + X= 52
30% x X + X x 100%=52
130% x X = 52
X= 52 x 100/130
X= 40
30%x+x=52
30%x + x = 52
0,3 . x + x . 1 = 52
x . \(\left(0,3+1\right)\) = 52
x . 1,3 = 52
x = \(52\div1,3\)
x = 40
Vậy x = 40
tìm X :
30% * X + X = 52
