Tìm x :
a) x x 405 = 86265
b) 8658 : x = 293
Tìm x: 8658 : 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
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
\(x\times405=86265\)
\(x=86265:405\)
\(x\text{=}213\)
\(89658:x=293\)
\(x=89658:293\)
\(x\text{=}306\)
\(x+126=480\)
\(x=480-126\)
\(x=354\)
\(x-209\text{=}435\)
\(x\text{=}435+209\)

Tìm x
a) x x 4 =64 b) 405 : x = 5
a) x x 4 =64 b) 405 : x = 5
x =64:4 x =405:5
x=16 x= 81
Tìm x
a) x x 48 = 26880
b) 5917 - x = 293
Tìm x: x x 405 = 86265
tìm X biết :
a) 7,3xX+Xx2,7-X=405
X x ( 7,3 + 2,7 - 1 ) = 405
X x 9 = 405
X = 405 : 9 = 45
Vậy x = 45
Tk mk nha
7,3 x X + X x 2,7 - X x 1 = 405
X x (7,3 +2,7 - 1) = 405
X x 9 = 405
X = 405 : 9
X = 45
7,3 x X+X x 2,7=405
=X(7,3+2,7-1)=405
=X x 9 = 405
X = 405:9=45
Vậy X= 45
CHÚC BẠN HỌC TỐT!
Tìm x:
x/1.2 + x/2.3+ x/3.4 +...+ x/2017.2018 = -1
X * 17 - X * 8 = 405 Tìm X
ai làm nhanh mk k cho miễn là đúng
Ta có :
X x 17 - X x 8 = 405
=> X x ( 17 - 8 ) = 405
=> X x 9 = 405
=> X = 405 : 9
=> X = 45
Vậy X là 45
k mk nha
