Answer:
x = 20
Step-by-step explanation:
Let's look at the first parallel lines (the ones with one arrow).
Because both these lines are parallel, we can say that (3x + 2) and (4x - 18) are equal due to the alternate interior angles theorem.
So we have to make both of these expression equal to each other, and then solve:
3x + 2 = 4x - 18
-x = - 20
x = 20 < --- this is your answer

So, this is a simple case of combining like terms. For now, ignore everything that doesn't have an "h"- the 1. Now, we have 5h+h-4h-2h. After that, we just move everything with a similar sign close to each other- but that's already done. Here, you can just add them all together like normal numbers, but remember that they don't get separated form the 'h". If it helps, drop the "h" and just add these numbers, then put it back on the end of your result.
You should end up with: 5h+h = 6h -4h-2h = -6h And then, 6h-6h =0h, or 0. Remember that constant we took out earlier? Add that to your answer now, resulting in a final answer of "1".
3.17, because there are about 1.056 quarts in one liter.
1.056 times 3 = 3.168, which, rounded to the nearest hundredth, is 3.17.

Answer:
Step-by-step explanation:
It means how many roots are there.
For example: The first one has no solution. But the second one has two solutions, 3 and 1.
Which means two x-values.
