Tính giá trị của x trong biểu thức sau : 357:(87:x)=110
\(357:\left(87:x\right)=110\)
\(\Leftrightarrow87:x=\dfrac{357}{110}\)
\(\Leftrightarrow x=\dfrac{3190}{119}\)

Em hãy tính giá trị của biểu thức.
9 : 0,25 - 0,9 : 1/4 x 10 + 22 -12 +2006
Giúp mik với !
3 bạn trả lời đang hoàng đầu tiên mik tick cho.
9:0,25-0,9:1/4x10+22-12+2006
=36-36+2016
=2016
\(9:0,25-0,9:\frac{1}{4}\times10+22-12+2006\)
\(=36-36+22-12+2006\)
\(=10+2006\)
\(=2016\)
mk ko ghi đề mà = lun nha
=9x4-0,9x4x10+22-12+2006
=36-3,6x10+22-12+2006
=36-36+22-12+2006
=0+22-12+2006=10+2006=2016

Tính giá trị biểu thức:
\(\frac{\left(1.2+2.3+3.4+...+98.99\right)x}{26950}=12\frac{6}{7}:\frac{3}{2}\)Trả lời giúp tớ, ai tham gia trả lời tớ tick hết!!! 10, 100, 1000 người trả lời tớ cũng tick hết!!
(1.2+2.3+3.4+...+98.99)x:26950=12 6/7:3/2
(1.2+2.3+3.4+...+98.99)x:26950=90/7:3/2
(1.2+2.3+3.4+...+98.99)x:26950=60/7
(1.2+2.3+3.4+...+98.99)x=60/7x26950
(1.2+2.3+3.4+...+98.99)x=231000
{[98x99x(98+2)]:3}x=231000
323400x=231000
x=231000:323400
x=5/7
