Answer:
a. 49
Step-by-step explanation:
so, basically turn the equation around! -15+64. because -15 is in parentheses, we know that it is negative, but another way you can do it is to take away the addition symbol and just use the negative as a subtraction one. so you could do 64-15 and you get 49. for b it's a little different, two negative cancel each other out so because there's a subtraction sign after 18 and there's a negative sign before 55 you can see that to simplify the equation it would be -18+55 or again 55-18. for c I think that one is pretty simple, just do 92-86 (I don't know if you see the pattern yet but most times you can just flip it around.) and for d you can do 17 plus 44 and then make the solution negative. I hope this helped a little!!

Answer:
5x+4y=49.50, where:
x is the price per sub
y is the price per drink
Step-by-step explanation:
From the information provided, you can say that the result of adding up the price per sub for the quantity plus the price per drink for the quantity is equal to 49.50 that is the total amount spent, which can be expressed as:
5x+4y=49.50, where:
x is the price per sub
y is the price per drink
First you need to distribute the -8
So you would get -8x-8 now distribute the 3 so it would be 3x-6
-8x-8+3x-6=-3+2 is how it should look
Now combine the -8x and 3x cause their like terms and also -8 and -6
-5x-14=-3x+2 now add -3 to both sides
-2x-14=2 and add 14 to both sides
-2x=12 all left to do is divide both by -2
X=-6
