(y:3) x 8 = 8 x 3198
( y : 3 ) x 8 = 8 x 3198
y : 3 = 8 x 3198 : 8
y : 3 = 3198
y = 3198 x 3
y= 9594
Vậy y = 9594
Nhớ k cho mình nhé! Thank you!!!
cách 1
( y : 3 ) x 8 = 25584
y : 3 = 25584 : 8
y : 3 = 3198
y = 3198 : 3
y = 1066
( x : 3 ) x 8 = 8 x 3198
\(\left(x:3\right)\times8=8\times3198\)
\(x\times\dfrac{1}{3}\times8=8\times3198\)
\(x\times\dfrac{8}{3}=25584\)
\(x=26684:\dfrac{8}{3}\)
\(x=9594\)
6 x ( y + 9845 ) = 29042 x 6
y =
( x : 3 ) x 8 = 8 x 3198
x =
\(6\times\left(y+9845\right)=29042\times6\)
\(y+9845\) \(=29042\times6\div6\)
\(y+9845\) \(=29042\)
\(y\) \(=29042-9845\)
\(y\) \(=19197\)
\(\left(x\div3\right)\times8=8\times3198\)
\(x\div3\) \(=8\times3198\div8\)
\(x\div3\) \(=3198\)
\(x\) \(=3198\times3\)
\(x\) \(=9594\)
Tìm x: (x:3)×8=3198×8
(x:3)*8=25584
x:3=25584:8
x:3=3198
x=3198*3
x=9594
Bài này dễ mak bn~
\(\left(x:3\right).8=3198.8\)
\(\left(x:3\right).8=25584\)
\(x:3=25584:8=3198\)
\(\Rightarrow x=3198.3=9594\)
( x : 3 ) x 8 = 3198 x 8
x : 3 = 3198
x = 3198 x 3
x = 9594
Tk nha!
Bài 21 : tìm ý bằng cách dựa vào tính chất của phép nhân :
A) (y: 3) x 8 = 8 x 3198
B) y x (y+ 9845 ) =29042 x 6
6 nhan (x+ 9845)= 29042 nhan 6
(x chia 3) nhan 8 =8 nhan 3198
\(6.\left(x+9845\right)=29042.6\)
\(x+9845=29042\)
\(x=19197\)
\(\left(x:3\right).8=8.3198\)
\(x:3=3198\)
\(x=1066\)
tim x
6*(x+ 9845)=29042*6
(:3)*8=8*3198
ai nhanh tick cho
a) 6*(x+ 9845) = 29042*6
6*(x + 9845) = 174252
x + 9845 = 174252
x = 174252 - 9845
x = 164407
b) (x:3)*8= 8 * 3198
x:3 *8= 25584
x:3 = 25584:8
x:3 = 3198
x = 3198*3
x = 9594
a,
6.(x+9845)=29042.6
x+9845=29042
x=29042-9845
x=19197
b,
(x:3).8=8.3198
x:3=3198
x=3198.3
x=9594
(y:3).8=8.3198
y:3=\(\frac{8.3198}{8}\)
y:3=3198
y=3198.3
y=9594
t nhé
\(\left(y:3\right)\times8=8\times3198\)
\(\left(y:3\right)\times8=25584\)
\(\left(y:3\right)=25584:8\)
\(\left(y:3\right)=3198\)
\(y=3198\times3\)
\(y=9594\)
( y : 3 ) x 8 = 8 x 3198
y : 3 = 3198 x 8 : 8
y : 3 = 3198
y = 3198 : 3
y = 1066
"Chúc bạn học giỏi"
Không tính kết quả cụ thể , tìm y :
1. ( y – 24 ) x 2020 = 2020 x 45
2. 30 x 3198 = 3198 x ( 230 - y )
Bài giải
1. ( y - 24 ) x 2020 = 2020 x 45
y = 45 + 24 ==> y = 69
2. 30 x 3198 = 3198 x ( 230 - y )
y = 230 - 30
y = 200
Chúc bạn học tốt !!!
