Me on this (10 points)

also, (btw this one relates with the problem )

_x9=_

1.)
1 gift takes (1/9)hour. This can be written as the rate.
We can make a proportion and relate the old number of gifts (1) to the new number of gifts (represented by unknown variable x) and the old time (1/9 hour) to the new time (3 hours). 
Then cross multiply and solve for x.


2.) I think this is just a restatement of the last step.
3 * 9 = 27

This statement is TRUE
In order for polygons to tessellate, polygons must be regular, or square or equilateral triangle
for example, if we take square the total number of degrees where the vertices meet = 90°+90°+ 90°+90°=360°
