bạn là trai hay gái

10 + 20 + 30 + 40 + 60 + 50

= 30 + 30 + 40 + 60 + 50

= 60 + 40 + 60 + 50

= 100 + 60 + 50

= 160 + 50

= 210

Vậy 10 + 20 + 30 + 40 + 60 + 50 = 210

Because multiplies of 6 are all even numbers.

The least possible number is 66198198

We have: (198−6):6+1=33(numbers)(198−6):6+1=33(numbers)

ANSWER: 33 numbers.

There are: 25−12=13(students)25−12=13(students)

There are: 20−12=8(students)20−12=8(students)

There are: 50−(13+8+12)=17(students)50−(13+8+12)=17(students)

ANSWER: 17 students

A = 2 x - 5 x + 2= 2 x + 4 - 9 x + 2= 2 x + 4 x + 2- 9 x + 2A=2X-5X+2=2X+4-9X+2=2X+4X+2-9X+2

2 x + 4 x + 22X+4X+2

9 x + 29X+2

X + 2 ∈ G C D ( 9 )X+2∈GCD(9)

X + 2 ∈ { ± 1 , ± 3 , ± 9 }X+2∈{±1,±3,±9}

X ∈ { - 1 , - 3 , 1 , - 5 , 7 , - 11 }X∈{-1,-3,1,-5,7,-11}

X ∈ { ± 1 , - 3 , - 5 , 7 , - 11 }
