7 14/18 since you can reduce this to 7 7/9:)
If they sold 89 calendars over 4 weeks, the 'equation' would look like (x = average calendars sold over 4 weeks):

If you solve it, you get:

Which is equal to
22.25. Hope this helps!
Hello!
To find the area of a hexagon you do 3

where a is one of the sides
Since the perimeter is 60 we can do 60/ the sides of the shape
60/6 = 10
So one side is equal to 10
you put that into the formula to get the area of a hexagon and you get 259.81
Hope this helps!
3 repeating digits are there
Y = 3
Just simplify the both sides, then add 7y to both then add 8 to both sides and divide both sides by 15
