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:
length = 60 cm
Step-by-step explanation:
ratio of width : length = 3 : 4 = 3x : 4x
perimeter = (2 × width ) + (2 × length) = 6x +8x = 14x
now perimeter = 210, hence
14x = 210 ( divide both sides by 14 )
x = 15
hence length = 4 × 15 = 60 cm

Answer:
A. f(x) = 1.75x
Explanation:
Every time you buy add a rose, the price increases 1.75
4.25 -> 6
9.50 -> 11.25
Answer:
The answer is B. $11.50 each
Step-by-step explanation:
2 pizzas @ $11 each is $22
3 garlic bread orders @ $4 each is $12
2 pitchers of soda @ $6 each is $12
$22+$12+$12 = $46
4 friends are splitting it evenly.
$46 divided by 4 = $11.50
