17,5 - ( 6 + x)= 8,74
17,5 - (6 + x) = 8,74
17,5-(6+x)=8,74
(6+x)=17,5-8,74
(6+x)=8,76
x=8,75-6
x=2,76
vay x=2,76
( 6 + X ) = 17,5 - 8,74
( 6+ X ) =8,76
X =8,76 - 6
X = 2,76

giải hộ mình nhá mình đang cần gấp
A, 17,5 - (6+x)=8,74
B,3/5m3.......601dm3
C, 1m2112dm2=........m2
A, 17,5 - (6+x)=8,74
6+x=17,5-8,74
6+x=8,76
x=2,76
B,3/5m3 =..600dm3
=>3/5m3<601dm3
C, 1m2112dm2=..2,12......m2
tim x :
a) x + 4/5 = 3/5 +3/4 b) 12/5 : x = 9/5 : 1/2
c) 7,32 - x = 2,4 + 3,49 d) 17,5 - ( 6 + x ) = 8,74
ai nhanh mk tick cho !
a.x + 4/5 = 3/5 +3/4
<=> x+ 4/5 = 27/20
<=>x =11/20
b,12/5 : x = 9/5 :1/2
<=>12/5 : x = 18/5
<=>x = 2/3
c,7,32 - x = 2,4 + 3,49
<=>7,32 - x = 5,89
<=>x = 3,43
Tìm x là số tự nhiên, biết
24,58+6,79<X<8,74+25,5
\(\Rightarrow31,37< x< 34,24\) Vì x \(\in N\Rightarrow x\in\left\{32;33;34\right\}\)
(1/2-1/3+1/4):(1/6*1/x)=17,5
[ 1/2 - 1/3 + 1/4 ] : [ 1/6 - 1/x ] = 17,5
\(\left[\frac{1}{2}-\frac{1}{3}+\frac{1}{4}\right]:\left[\frac{1}{6}-\frac{1}{x}\right]=17,5\)
\(\Rightarrow\frac{5}{12}:\left[\frac{1}{6}-\frac{1}{x}\right]=\frac{35}{2}\)
\(\Rightarrow\frac{1}{6}-\frac{1}{x}=\frac{5}{12}:\frac{35}{2}\)
\(\Rightarrow\frac{1}{6}-\frac{1}{x}=\frac{1}{42}\)
\(\Rightarrow\frac{1}{x}=\frac{1}{6}-\frac{1}{42}\)
\(\Rightarrow\frac{1}{x}=\frac{1}{7}\)
\(\Rightarrow x=1:\frac{1}{7}\)
\(\Rightarrow x=7\)
Học tốt # ^-<
( 1/2 - 1/3 + 1/4 ) : ( 1/6 - 1/x ) = 17,5
( 6/12 - 4/12 + 3/12 ) : ( 1/6 - 1/x) = 17,5
5/12 : ( 1/6 - 1/x ) = 17,5
1/6 : 1/ x = 5/12 : 17,5
1/6 : 1/ x = 1/42
1/x = 1/6 : 1/42
1/x = 7
1 : x = 7
x = 1:7
x = 7
tìm x
(1/2-1/3+1/4):(1/6-1/x)=17,5
\(\frac{\frac{1}{2}-\frac{1}{3}+\frac{1}{4}}{\frac{1}{6}-\frac{1}{x}}=17.5\)
\(\frac{\frac{1}{6}+\frac{1}{4}}{\frac{1}{6}-\frac{1}{x}}=\frac{35}{2}\)
\(\frac{\frac{5}{12}}{\frac{1}{6}-\frac{1}{x}}=\frac{35}{2}\)
