89 658 : X = 293
Tìm x
a) x x 48 = 26880
b) 5917 - x = 293
Bài 1 : Tìm x
X x 405 = 86265
89658 : X = 293
Bài 1 :
X x 405 = 86265 89658 : X = 293
X = 86265 : 405 X = 89658 : 293
X = 213 X = 306
\(x\times405=86265\)
\(x=86265:405\)
\(x=213\)
\(89658:x=293\)
\(x=89658:293\)
\(x=306\)
Tìm x, biết rằng:
\(\frac{\frac{2}{7}+x+\frac{2}{17}-\frac{2}{293}}{\frac{3}{7}+\frac{3}{5}+\frac{3}{17}-\frac{3}{293}}-\frac{2}{3}=0\)
=>\(\frac{x+\frac{2}{7}+\frac{2}{17}-\frac{2}{293}}{\frac{3}{7}+\frac{3}{5}+\frac{3}{17}-\frac{3}{293}}-\frac{2}{3}=0\)
=>\(\frac{x+0,396535406}{1,194803109}-\frac{2}{3}=0\)
=>x+0,396535406:1,194803109-2/3=0
x+0,396535406:1,194803109=0+2/3=2/3
còn lại tự giải nha nhiều quá
Tìm X
X x 405= 86 265
89 658 : X = 293
X + 126 = 480
X - 209 = 435
X : 13 = 200 + 5
X x 40 = 26 000 - 400
962 456 - X = 342 x 7

293 x 45 + 293 x 50 x 5 =
Tính nhanh rút thừa số chung
293 x 45 + 293 x 50 x 5
= 293 x 45 + 293 x 250
= 293 x ( 45 + 250 )
= 293 x 295
= 86435
293 x 45 + 293 x 50 x 5
= 293 x ( 45 + 50 + 5 )
= 293 x 100
= 29300
k minh nha
Tìm x:
a/ 1298- 483873 : ( x+740)= 682-333:9
b/ 370+ 389.( 293-x) = 110457
5 tk
a) 1298 - 483873 : ( x + 740 ) = 682 - 333 : 9
1298 - 483873 : ( x + 740 ) = 682 - 37
1298 - 483873 : ( x + 740 ) = 645
483873 : ( x + 740 ) = 1298 - 645
483873 : ( x + 740 ) = 653
( x + 740 ) = 483873 : 653
x + 740 = 741
x = 741 - 740
x = 1
b ) 370 + 389 . ( 293 - x ) = 110457
389 . ( 293 - x ) = 110457 - 370
389 . ( 293 - x ) = 110087
( 293 - x ) = 11087 : 389
293 - x = 283
x = 293 - 283
x = 10
Học tốt nhé###
\(a,1298-483873:(x+740)=682-333:9\)
\(\Leftrightarrow1298-483873:(x+740)=682-37\)
\(\Leftrightarrow1298-483873:(x+740)=645\)
\(\Leftrightarrow483873:(x+740)=653\)
\(\Leftrightarrow x+740=741\Leftrightarrow x=1\)
Vậy x = 1
