Divide total cups he drank by the # of cups in each bottle. 
7 ÷ 3= 2.3333
Since each bottle only holds 3 cups, he drank 3 bottles of water. He didn't drink all the water in the third bottle, but he started drinking the third bottle. 
ANSWER: 3 bottles

This equation is in slope-intercept form; y = mx+b.
m is the slope and b is the y-intercept, so to find the slope you'd look at the coefficient of x.
In this equation, y = 3x+5, the coefficient of x is 3, so that means that the slope of this equation is 3.
Answer is:
3 is the slope

Answer:
   b ≈ 2.7
Step-by-step explanation:
The missing angle A is ...
   A = 180° -53° -80° = 47°
The law of sines tells you ...
   b/sin(B) = a/sin(A)
   b = sin(80°)×2/sin(47°) ≈ 2.6931
Side b is about 2.7 units.
