Iam trying to my 3rd grader to complete the tables to find how many ways each can be solved. here’s one. ! john has 42 model cars. he wants to put 3 cars on some shelves and 2 cars on other shelves. how many ways can he display his model cars? shelves with 3 cars: shelves with 2 cars: total cars: how do i solve this?

Shelves with 3 cars: 10

Shelves with 2 cars: 6

Total:42

Shelves with 3 cars: 6

Shelves with 2 cars: 12

Total:42

There are many ways to do this. So what I did was multiply 3 by a number like 10. Then I took the 2 and multiplied it  by 3. i added the numbers 30+6=36. that doesn't work so i tried 2 multiplied by 6. 30+12=42. Hope this helped a little. :D

what "following statement"?

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
