The number of bottles in a full box is 12.
<u><em>Explanation</em></u>
Suppose, the number of bottles in a full box is 
So, the number of bottles in <u>three</u> full boxes 
Now, two more boxes are added, both of which have <u>one fewer bottle than the other three</u>. So, the number of bottles in these two boxes 
As there were 9 bottles initially and now there are 67 bottles in the fridge, <em><u>so the equation will be</u></em>....

Thus, the number of bottles in a full box is 12.
The answer would be 0, as the slope of a line is definite as it pitch, or rate of increase. So if the line were going up to the right it would be positive, to the left, negative. An undefined slope would be the exact opposite of that slope. The slope you have, when written in y=mx+b is y=4

Step-by-step explanation:
A pool calculator, or a few simple equations, will give you the ... chemicals into your pool willy nilly, you need to know how much to use. .... key part of your equations is this: One cubic foot of water contains 7.5 ... Rectangular or Square Pool Volume ... 3.14 × 144 × 4 × 7.5 = 13,564.8 gallons ...
circumference of a circle (C)
C = πd or 2πr ( because d 2 x r)
r= 18 miles given
d= diameter
r= radius
d = 2 x r
d = 2 x 18 = 36 miles
2) C = πd
C = 3.14 x 36 = 113.04 miles
3) approximate measure of C = 22/7 x 36= 113.14 miles
