Step-by-step explanation:
In any right triangle, the Pythagorean theorem states:
, where
and
are two legs of the triangle and
is the hypotenuse.
Plugging in given values, we have:

They would have ran 0.45 miles per minute. Multiply this by 60 minutes(in which make an hour) and you will get 27 miles.
|RZ|=0.5|SW| therefore 2|RZ|=|SW|.
5x - 20 = 2 · 30
5x - 20 = 60 |add 20 to both sides
5x = 80 |divide both sides by 5
x = 16
Answer:
1
Step-by-step explanation:
The denominator in 9 is one. This also applies for all numbers without a denominator.
Hope this helps :)
You would divide -204 divide it by -17 and you would get 12
X=12
