25.50 = 7d + 2p
52.50 = 5d + 10p
These are the two equations we're going to use to determine the price of popcorn.
First we need to eliminate one set of variables. Let's eliminate the drinks.
127.50 = 35d + 10p
-367.50 = -35d + -70p
-240 = 0d - 60p
-240 = -60p
P = 4.00
So, popcorn is $4, right? Let's keep working on the problem so we can double check...
So, now let's add the $4 as the variable for P.
25.50 = 7d + 8
52.50 = 5d + 40
17.50 = 7d
12.5 = 5d
d = 2.5
d=2.5
This checks out! Since both equations state that drinks are 2.50, that means we have the right pricing for popcorn... $4.00
Popcorn is $4.00, drinks are $2.50

the answer is 50 degrees
Step-by-step explanation:
the sum of all three angles of a triangle is always 180 degrees.
first you have to combine all terms, equal it to 180, and then solve for x.
4x-20+2x+2x=180
8x-20=180
8x=200
x=25
then to find angle G you multiple x times 2 (2x)
2 × 25 = 50
A. 4-x
2x-8+3(4-x)
multiply 3(4-x)
2x-8+ 12- 3x
add -8 and 12
add 2x and -3x
4-x
i believe that A. 4-x is correct.
6=2+2+2
-In mathematics, a quaint number is a number that can be written as the sum of two or more prime numbers.
-The multiple divisors of 6 in a factor tree are 2,2 and 2
-6 can thus be written as 2+2+2:
-Hence 6 is a quaint number
