Tìm x
92.4-27=(x+350):x+315
tìm x:
\(697:\frac{15.x+364}{x}=17\)
\(92.4-27=\frac{x+350}{x}+315\)
tìm x:
\(697:\frac{15.x+364}{x}=17\)
\(92.4-27=\frac{x+350}{x}+315\)
\(697:\frac{15x+364}{x}=17\)
\(\frac{15x+364}{x}=697:17=41\)
\(\frac{15x}{x}+\frac{364}{x}=41\)
\(15+\frac{364}{x}=41\)
\(\frac{364}{x}=41-15=26\)
\(x=364:26=14\)
\(92.4-27=\frac{x+350}{x}+315\)
\(\frac{x+350}{x}+315=341\)
\(\frac{x+350}{x}=341-315=26\)
\(\frac{x}{x}+\frac{350}{x}=26\)
\(1+\frac{350}{x}=26\)
\(\frac{350}{x}=26-1=25\)
\(x=350:25=14\)
92.4-27=\(\frac{x+350}{x}\)+315
92.4-27=x+350 phan x +315
KUDO SHINICHI:
Bài làm:
\(92.4-27=x+\frac{350}{x}+315\)
\(368-27=x+\frac{350}{x}+315\)
\(341=\frac{x}{350+315}\Leftrightarrow341=x:350+315\)
\(341=x:665\)
\(x=665.341\)
\(\rightarrow x=226765\)
Vậy x=226765
:3, Chúc bạn học tốt!!
92.4-27=x+350/x +315
368 - 27 = x+350 : x + 315
341 = x : (350 + 315)
341 = x : 665
x = 665 x 341
x = 226765
tìm số tự nhiên x biết
92.4-27=a+350/a +315
Lời giải là
92.4−27=a+350a+315
368−27=a+350a+315
341=a+350a+315
a+350a=341−315
a+350a=26
a+350=26.a
26.a−a=350
(26−1).a=350
25.a=350
a=350:25
a=14.
1 .tìm x biết :
92.4 - 27 = ( x + 350 ) : x + 315
\(92.4-27=\left(x+350\right):x+315\)
\(\Leftrightarrow368-27=\left(x+350\right):x+315\)
\(\Leftrightarrow341=\left(x+350\right):x+315\)
\(\Leftrightarrow\left(x+350\right):x=341-315\)
\(\Leftrightarrow\left(x+350\right):x=26\)
\(\Leftrightarrow\left(x:x\right)+\left(350:x\right)=26\)
\(\Leftrightarrow1+350:x=26\)
\(\Leftrightarrow350:x=26-1\)
\(\Leftrightarrow350:x=25\)
\(\Leftrightarrow x=\dfrac{350}{25}=14\)
Vậy x=14
1.TÌM X,
A. 697:\(\frac{15.X+364}{X}\)=17
B. 92.4-27=\(\frac{X+350}{X}\)+315
a) \(697:\frac{15X+364}{X}=17\)
\(\Rightarrow\frac{15X+364}{X}=697:17=41\)
\(\Rightarrow15X+364=41X\)
\(\Rightarrow364=41X-15X=26X\)
\(\Rightarrow X=14\)
A.suy ra: 15x+364/x=41
suy ra: 15x/x+364/x=41
suy ra: 15 + 364/x=41
suy ra: 364/x =26
suy ra: 364:x=26
suy ra: x= 14 (T/M)
B. 92.4-27=x+350/x+315
suy ra: 341=x/x+ 350/x +315
suy ra: 26 =1+350/x
suy ra: 25=350/x
suy ra: 350:25=x
suy ra: 14=x (T/M)
Vậy a. x=14
b. x=14
Giúp mik nha
92.4 - 27 = (x + 350 ) : x + 315
92.4-27=(x+350) : x + 315
368-27=x : x + 350 : x + 315
341=1+350 : x +315
341-315-1=350 : x
25=350 : x
350 : 25=x
14=x
vậy x=14
Đáp án là \(\frac{-250}{179}\)nha bạn.
