I think x equals 13 because 13+3=16 and 16 divided by 2 equals 8
Monkey, or giraffe, elephant! i can’t choose lol
That's of course the 30/60/90 right triangle.
If you need to see the algebra, the acute angles in a right triangle are complementary, adding to 90 degrees:
x + 2x = 90
3x = 90
x = 30
I'll do the first one:
Both novels.
Student 1 picks a novel. There are 3 novels out of 6 books total.
Now there are 5 books left.
Student 2 picks a novel. There are 2 novels out of 5 books since the other student took a novel.
To find the probability you would multiply the probability student 1 gets a novel and the probability student 2 gets a novel.
![\frac{3 Novels}{6 Books} x \frac{2 Novels}{5 Books} = \frac{6}{30} = \frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20Novels%7D%7B6%20Books%7D%20x%20%20%5Cfrac%7B2%20Novels%7D%7B5%20Books%7D%20%3D%20%20%20%5Cfrac%7B6%7D%7B30%7D%20%3D%20%20%5Cfrac%7B1%7D%7B5%7D%20)
So the probability is 1/5. Or 20%
Answer:
<u>10</u>
Step-by-step explanation:
If 10+x is 5 more than 10
this could be written as
10+x=15<----
First, subtract 10 on both sides.
then you will get x=5
5*2=<u>10</u>
