Answer:
z = 60
Step-by-step explanation:
z/3 = 20. (Multiply both sides by 3 to isolate ‘z’)
20 • 3 = 60
Answer:
227 sides
Step-by-step explanation:
The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:
40500 = 180(n-2)
225 = n-2
227 = n
Therefore, the number of sides in the regular polygon is 227.
Answer: 3 Sets of the 4 post cards and 3 of the single post cart sets.
Step-by-step explanation:

You would now have 12 postcards now you have to buy 3 of the single set to get to 15 cards
Answer:
-2y+6
Step-by-step explanation:
Multiply (y-3) by -2
If they have opposite signs the point can be in either the second or fourth quadrants.
-x and +y is in the second quadrant
+x and -y is in the fourth quadrant.
