717.3
The sum of angles of a pentagon is 540°, so x must be chosen to make that so.
85 + 110 + x + 120 + 120 = 540
540 -435 = x = 105
_____
The formula usually used to find the degree measure of the internal angles of an n-sided polygon is (n -2)·180°. For n=5, this is 3·180° = 540°.
Answer:
In 4 months, they will both have 132 stamps.
Step-by-step explanation:
Let x = # of months
52 + 20x = 68 + 16x
4x = 16
x = 4
Plug x value into both expressions and see if it checks out
52 + 20(4) = 68 + 16(4)
52 + 80 = 68 + 64
132 = 132

Second One: No
Step-by-step explanation:
Direct Variation Formula: y=kx
1. every single on is y=x times 6, fits the formula
2. there is no easy multiplying repeating pattern of how x=y
