\(128673-x=5050:5\\ 128673-x=1010\\ x=128673-1010\\ x=127663\)
128673-x=5050:5=1010
=>x=128673-1010=127663.
128 637 - x = 1010
x = 128 637 - 1010
x = 127 627
\(128673-x=5050:5\\ 128673-x=1010\\ x=128673-1010\\ x=127663\)
128673-x=5050:5=1010
=>x=128673-1010=127663.
128 637 - x = 1010
x = 128 637 - 1010
x = 127 627
( x + 1 ) + ( x + 2 ) + ( x + 3 )+ .... + ( x + 100) = 5050.
1+2+3+.....+x=5050
tìm x
a) Tìm x biết: (x + 1) + (x + 2) + (x + 3) + … + (x + 99) + (x +100) = 5050
X+(27150-135*200):5=53*128+69*128-22*128
(x+1)+(x+2)+(x+3)+......+(x+100)=5050
Hỏi x bằng bao nhiêu?
tính nhanh :
( 3737 x 50 - 5050 x 36 ) : ( 1 + 2 + 3 + ............. + 100 )
tìm x
a) ( x+ 1) +(x + 2)+..........+(x + 100)=5050
b) (x +1) x x=2550
|x-1|+|x-2|+...|x-100|=2500
+ xét trường hợp x\geq 0
\Rightarrow |x-1|+|x-2|+...|x-100|=2500
hay x-1+x-2+.................+x-100=2500
\Rightarrow 100x-5050=2500
\Rightarrow x=755
+ xét trường hợp x<0
\Rightarrow |x-1|+|x-2|+...|x-100|=2500
hay 1-x+2-x+.............+100-x=2500
\Rightarrow 5050-100x=2500
\Rightarrow x=255
Tìm x, biết x là số tự nhiên và:
(x+1)+(x+2)+(x+3)+........+(x+100)=5050
