Xl vì nó hơi nghiêng 

31 tháng 1 2018

Ta có x + y = x.y

=> x + y - x.y = 0

=> x + y(1 - x) = 0

=> x - y(x - 1) = 0

=> (x - 1) - y(x - 1) = -1

=> (x - 1) . (1 - y) = -1

=> x - 1 và 1 - y là ước của -1 = {1;-1}

Nếu x - 1 = 1; 1 - y = -1 =>  x = 2 ; y = 2

Nếu x - 1 = -1; 1 - y = 1 => x = 0; y = 0

2016*20162015-2015*20162016+2017=20162017

\(x\) - (10 - \(x\)) = \(x\) - 22

\(x\) - 10 + \(x\) = \(x\) - 22

2\(x\) - 10 = \(x\) - 22

2\(x\) - \(x\)  = -22 + 10

\(x\)         = - 12

 trả lời cho mik đi

hình tự ngồi mà vẽ

ta có : góc AOD = góc COB ( 2 góc đối đỉnh )

         => góc COB = 110 độ

Ta có : AOD + DOB = 180 ( 2 góc kề bù )

            110 + DOB = 180

       => DOB           = 70

lại có góc AOC = góc DOB ( 2 góc đối đỉnh )

 =>                     = 70

Vậy góc DOB = 70

    COB = 110

AOC = 70

lm đc rồi nhưng đừng có k, cho 10 cái cx k nhận

số t1:

\(70 : ( 4 + 1 ) . 1 = 14\)

số t2:

\(70 - 14 = 56\)

5 tháng 4 2022

Gấp `4` lần số thứ `1` được số thứ hai

Số thứ `1=1/4` số thứ 2

Tổng số phần bằng nhau `1+4=5(phần)`

Số bé: `70:5xx1=14`

Số lớn:`70-14=56`

`@An`

a: KE=5-2=3(cm)

b: KO=KE+EO=3+2=5(cm)

26 tháng 1 2022

a) \(KE=ME-MK=5-2=3cm\)

b) \(KO=KE+EO=3+2=5cm\)
