Tìm x : X x 4 + X =55,35
X x 4 x X = 55,35
tìm X
\(x\times4\times x=55,35\)
\(x\times x=55,35:4\)
\(x\times x=13,8375\)
\(\Rightarrow x=3,719879....\)
Tìm x biết:
x * 4 + 0,5*x= 55,35
x * 4 + 0 , 5 * x = 55 , 35
x * ( 4 + 0 , 5 ) = 55 , 35
x * 4, 5 = 55 , 35
x = 55 , 35 : 4 , 5
x = 12 , 3
Vậy x = 12 , 3
Bài 1: Tìm x:
X x 4 + 1 / 2 x X = 55,35
\(4x+\frac{1}{2}x=55,35.\)
\(\Leftrightarrow\left(4+\frac{1}{2}\right)x=55,35.\)
\(\Leftrightarrow4,5x=55,35\)
\(\Leftrightarrow x=12,3\)
X x 4 + 1/2 x X = 55,35
tìm X
hộ mình với mình đang cần gấp
\(x\cdot4+\frac{1}{2}\cdot x=55,35\)
\(x\cdot\left(4+\frac{1}{2}\right)=55,35\)
\(x\cdot\frac{9}{2}=55,35\)
\(x=12,3\)
tìm x
x*4+1/2*x=55,35
giúp mình nhé
x*4+1/2*x=55,35
=x*(4+1/2)=55,35
=x*4,5=55,35
=55,35:4,5
=12,3
Tìm X
a, X + 20% x X = 7,2
b, X x 4 + 1/2 x X = 55,35
bạn có thể diễn giải ra không Võ Hoàng Minh Thư
Tìm x: x 9,25 + 75% x = 55,35
điền >,<=:
0.01m3...1/99m3
tìm x
x x 4 + 1/2 x x =55,35
Bài 1: 0,01m3 < 1,99m3
Bài 2: Tìm \(x\):
\(x\)x 4 + \(\frac{1}{2}\)x \(x\)= 55,35
\(x\)x (4 + \(\frac{1}{2}\)) = 55,35
\(x\)x \(\frac{9}{2}\)= 55,35
\(x\)= 55,35 : \(\frac{9}{2}\)
\(x\)= 249,075
1,
\(0,01m^3=\frac{1}{100}m^3\); vậy \(\frac{1}{100}m^3< \frac{1}{99}m^3\)
2, Lời giải
\(x\cdot4+\frac{1}{2}\cdot x=55,35\)
\(\Rightarrow x\cdot\left(4+\frac{1}{2}\right)=55,35\)
\(\Rightarrow x\cdot4\frac{1}{2}=55.35\)
\(\Rightarrow x\cdot4,5=55,35\)
\(x=55,35:4,5\)
\(x=12,3\)
thanks for answering!!!!!!!!!!!!!!!!!
X x 4 + 1/2 x X =55,35
`!`
`x xx 4 +1/2 xx x=55,35`
`=> x xx ( 4+1/2) =55,35`
`= x xx 9/2=55,35`
`=>x= 55,35 : 9/2`
`=>x= 3,075`
