the answer is that any number of y is a positive
Step-by-step explanation:
look very closely and you will see what I was just talking about
Let 
be the weight of the fresh coffee, and 
be the weight of the roasted coffee. The equation described by the first sentence is
In this case, we know and want to solve for : the equation becomes
To solve for , multiply both sides by 25/22:
In this problem all the necessary informations are provided. Total capacity of the tank is given as 2560 gallons. It is also given that after 2 weeks or 14 days , only 1944 gallons of water is left. The number of days the whole tank will be empty is required to be found.
Let us assume that the number of days required to empty the tank = x
Then
Now amount of water consumed in 14 days = 2560 - 1944
= 616 gallons
So
616 gallons of water used in = 14 days
2560 gallons of water will be used in = (14/616) * 2560
= 58.18
Then the whole tank will last approximately 58 days if calculated to the nearest whole number.
It’s really blurry, I can’t help :(
