Answer: 16/45 of the spool
Step-by-step explanation:
2/5 of 8/9
2/5 * 8/9 = 16/45 (multiply numerators, and multiply denominators)
Cannot be further simplified.
Answer:
the answer is 9
Step-by-step explanation:
Answer:
(3,-3)
Step-by-step explanation:
First you divide 2 out of the first equation and it turns into 5x+y=12.
Then you write one on top of the other so you can add them. It looks like:
5x + y = 12
-5x + y = -18
Then you add them together and the 5x's cancel each other out and you are left with 2y = -6
So then you divide both sides by 2 and get y = -3
Then you plug -3 into the second equation because it is simpler and get -5x - 3 = -18
So then you add three to both sides and get -5x = -15
And finally you divide both sides by -5 and get x=3
The orthocenter of an obtuse triangle always lies : C. On the outside of the triangle
<span>Attitude of an obtuse triangle will not go through the midpoint line of the triangle and the three points of the triangle will intersect with each other at some point, so it must lies outside of the triangle</span>
For the first equation just solve for y
then plug into the 2nd one
then solve for x
