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

I can’t find a picture but i can explain how to find the LCM of two numbers.
Let’s say we want to find the LCM of 10 and 12.
We first write the prime factorization of both numbers:
10= 2x5
12= 2*2*3
We multiply the highest degree of the numbers:
That is, 2*2*3*5=60

You can also watch this video to get a better idea on how to find the LCM of two or more numbers.
Hope this helped.
Step-by-step explanation:
2.4 (-1/2)
=2.4×(-0.5)
=-1/2
Answer:
D
Step-by-step explanation:
A = (pi)(r)^2
A = (3.14)(3.7)^2
A= ~43
yo sup??
The number can't be a probability of an event cause probability of an even lied between 0 and 1 whereas the number given to use is -0.25.
Since probability can't be negative therefore it isn't a probability of an event.
Hope this helps.
