x/126=-7/24 x -6/11
X/126=-7/24×-6/11
tim x
x/126=-7/24*-6/11
x = 441/22 nha ban. chọn mình nha. đúng 100%
X/126=-7/24×-6/11
Tìm x, biết
x/126= -7/24. -6/11
Ta có: \(\dfrac{x}{126}=\dfrac{-7}{24}.\dfrac{-6}{11}\)
\(\Rightarrow\dfrac{x}{126}=\dfrac{7}{44}\)
\(\Rightarrow x=\dfrac{126.7}{44}\)
\(\Rightarrow x=\dfrac{441}{22}\)
Vậy \(x=\dfrac{441}{22}.\)
ta có x/126 =-7/24 * -6/11
suy ra x/126 =7/44
x*44=126*7
x*44 = 882
x= 882/44= 441/22
Ta có : \(\frac{x}{126}\)=\(\frac{-27}{24}.\frac{-16}{11}\)
=> \(\frac{x}{126}=\frac{7}{44}\)
=> \(x=\frac{126.7}{44}\)
=> \(x=\frac{441}{22}\)
Vậy : \(x=\frac{441}{22}\)
2 tìm x,biết;
a)x-1/4=-3/8.2/5
b)x/126=-7/24.-6/11
a) x -1/4 = -3/8 . 2/5
x - 1/4 = -3/20
x = -3/20 + 1/4
x = 1/10
b) x/126 = -7/24 . -6/11
x/126 = 7/44
\(\Rightarrow\)x = rỗng
a, x- 1/4 = (-3/20)
x= 1/10
b, x/126 = (7/44)
x = 441/22
tìm x, biết \(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)
tìm x biết : x/126 = -7/24 . -6/11
mk tìm mãi ko ra . giúp mk vs
\(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)
\(\Leftrightarrow\frac{x}{126}=\frac{7}{44}\)
\(\Leftrightarrow x.44=126.7\)
\(\Leftrightarrow x.44=882\)
\(\Leftrightarrow x=882:44\)
\(\Leftrightarrow x=\frac{441}{22}\)
x126=−724×−611
⇔x126=42264
⇔x126=744
⇔x=126×744
⇔x=126×744
⇔x=44122
x/126 = -7/24 x -6/11
x/126 = 7/44
x = 126 x 7/44
x= 441/22
Tìm \(x\), biết:
\(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)
Help!
\(\frac{X}{126}=\frac{-7}{24}.\frac{-6}{11}\)
\(\frac{X}{126}=\frac{42}{264}\)
\(\frac{X}{126}=\frac{7}{44}\)
\(X=\frac{7}{44}.126=\frac{882}{44}=\frac{441}{22}\)
Vậy x = 441/22
\(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)
\(\Rightarrow\frac{x}{126}=\frac{7}{44}\)
\(\Rightarrow x.44=126.7\)
\(\Rightarrow x.44=882\)
\(\Rightarrow x=882:44\)
\(\Rightarrow x=\frac{441}{22}\)
\(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)
Giúp mình nha~!!! Mình không làm được bài này !!!
