360. Since 20 gallons makes 1/2 gal of maple syrup. Multiply 20*18. I cant explain because its to much to write. But I hope this helps. :^)
I think you could try to multiply all three of the first prism and then multiply all three of the second prism. Then you can compare both of them to each other, and there will be a difference.
1. the formula for the slope is

where (a,0) is x1, y1 and (0,2a) is x2, y2. try to see if you can do it now (:
2. take a number x, then step by step do whatever the question asks for example "First, 3 is subtracted from x" so you know the first thing you need to do is x-3, then go on and you'll get an equation which you can use to solve for x, try it!
3. make a set, S, which has multiples of 7. then make a set, T, which has multiples of 13.
now the intersection of S and T is a set having all elements of S, also found in T (basically the numbers that are common to both). try doing it now!
for fourth, this requires a profit formula(that I do not know), must be explained in your book, try going over it, I'm sure you'll find it there!
Answer:
The nearest hundredth would be in the second decimal place. It would be 967.99 as you would round down to get there.
