Answer:
There are 8 pints in a gallon.
128 pints of OJ were drunk.
Answer:

Step-by-step explanation:
We can model this function using the equation of a line:

Where a is the slope of the line and b is the y-intercept.
To find the values of a and b, we can use the two points given:
(-9, -3):


(-12, 4):


If we subtract the second equation from the first one, we have:




Then, finding the value of b, we have:



So the equation is:

Answer: 15/2 or 7.5
Step-by-step explanation:
2/3x = 5
5 divided by 2/3 or 5 x 3/2
= 15/2 or 7.5
