Can someone give all the answers to this? ()

Top one would be 18 on the pyramid.

No, the top one would be 33. You're adding the brick next to another brick together for example; 3 and 4 are together; makes 7. 4 and 5 are together makes 9. 5 and 3 are together makes 8.

2. That's unit rate; You have to divide 225 by 15 which gives you 15. 15 x 15 = 225 so, 15 x ( 1 hour ) = 15 hours.

6. Y = 34. 98 + 4 = 102. 102 divided  by 3 = 34. 102 - 4 = 98.

That's all I can do sorry
