B and C

Step-by-step explanation:

Since the price of one slice is B then 2 pieces has the price of 2B amd the total cost equals 2B+J

then to calculate the total cost for 7 days you have to multiply the cost for one day by 7 which is 7(J+2B) or if you expand that phrase you get 7J+14B

We can put in 6 - 2x for y:

2x + y = 6
2x +(6 - 2x) = 6
2x + 6 - 2x = 6
6 = 6

Since this statement is true:
x and y are all real numbers.

Hope this helps!
