TURKEY 0.15xy+20y

GOBBLE 0.20xy+0y

x is the number of texts and y is the number of months

400 texts will need to be sent each month because solving the equation 0.15xy+20y=0.20xy+0y

0.15xy+20y=0.20xy

-0.05xy+20y=0

-0.05xy=-20y

turn -0.05xy into (-y/20)x

(-y/20)x=-20y

((-y/20)x=-20y)/-y/20

x=-20y/-y/20

x=400

TURKEY plan because 0.15(500)y+20y is 95y and 0.20(500)y+0y is 100y, meaning TURKEY would be cheaper.

For a regular n-gon:
snow_lady [41]
I believe the sum of the interior angles is the number of sides (n), subtracted by 2, and multiplied by 180.
(n - 2) x 180 = sum of interior angles of a n-gon

I also believe that the sum of exterior angles of a n-gon equals to 360 degrees.

laiz [17]

Answer:

I believe its 36

Step-by-step explanation:

so what i id is a took apart the answer, if 1 1/4 if 10 cups the 1/4 1/4 1/4 1/4 1/4 would also be 10 cups, so now i know that 1/4 = 2 servings

eso i took 3. 1/4 and that gave me 6 and now add the previous which is 10 so its 16 and i have   2 cups left

from here i knew 1 cup and 1/4 is 10 so subtract 1/4 which is -2 servings and you have 8 and 8+8 is 16 so

then i added

16+16= 36

which leads to my final answer of 36

Im so sorry if im wronge but if its right please give brainlest

In triangle XYZ, m∠Z > m∠X + m∠Y. Which must be true about △XYZ?
Solnce55 [7]
Since z is GREATER THAN two angles in the triangle it must be obtuse..
meaning it is GREATER THAN 90 degrees this means that the other two angles cannot equal 90 degrees they have to be less

m∠X + m∠Y < 90°
