let the price of pizza and soda( per 2 litre bottle) be x and y
from 1st condition
12x+2y=137.6.....(1)
from 2nd condition
x+y =11.95.......(2)
multiply eq. (2) by 2
2x+2y=23.9.....(3)
subtracting (1) and (3)
12x+2y=137.6
2x+2y= 23.9
10x = 113.7
x=113.7/10
x=11.37
2(11.37)+2y=23.9
22.74+2y=23.9
2y=23.9-22.7
2y=1.2
y=0.6
So the prices of the pizza and soda are 11.37 and 0.6 dollars.
Hello,
Dividing by 0 is not defined so let s take x different from 4 and -4 and then we can write:
As
Thanks
A and D because it is basically saying 3:36 so when you simplify it comes down to 1:12
It's c 18, because the diameter is the longest chord so it would be greater than 15.
