Well to solve for r, what you would need to do is make up an equation based on the expressions that represent the segments of the line in the image.
JK represents the first aspect of the line and is equal to 6r.
Likewise, KL represents the second component of the line and is equal to 3r.
We also know the total value from the first point to the last one, and that is 27.
Now simply add the first 2 expressions that represent the segments of the line and make it equal to the total length of the line, 27 and then solve for r.
6r + 3r = 27
9r = 27
r = 27/9
r = 3.
So now we know that JK is 6 • 3 = 18 and KL is 3 • 3 = 9, thus adding both together will give a value of 27, 18 + 9 = 27.
The solution is C.3
Answer:
a=100 hope it may help u
Step-by-step explanation:
82.45×10a=82450
824.5a=82450
a=824500/8245
a=100

My experience in higher education was unusual and erratic. I eventually earned a master’s degree in International Studies, but long before that I was a high-school dropout.
One thing I haven’t talked about much is that I’ve never been able to learn higher math: algebra, geometry, calculus, or anything of the sort. It’s not for lack of trying, or at least it wasn’t for a while. (I have zero interest in trying to learn it these days.)
No, I tried and I just couldn’t learn. I tried over and over and it never got any easier. In the U.S. educational system, I failed to progress beyond seventh or eighth grade level math. I’m not sure what the equivalent is elsewhere, but for me I could understand the very elementary principles of algebra and geometry but nothing beyond that.
Lots of people tried to help. I read books and went to study groups. But no matter what I did, it didn’t sink in.
Answer:
X = -4 or X = 1
Step-by-step explanation:
- 3x -.4/x^2
- x^2 + 3x -4 =0
- (X + 4 ) or ( x-1 )
- X = -4 or X= 1
that I think (・∀・) I'm not sure it may wrong.
Answer:
There are 3744 possible full house hands in five-cards poker.
There are 5148 possible flush hands in five-cards poker.
Step-by-step explanation:
For a full house, we have to have 2 out of 4 of the same value with 13 different values, plus 3 out of 4 of the same value with 12 different values (because one was used for the first 2 cards). We can count those different options by using combinatorics (choosing 3 out of 4 and (in probability, and means those two are independent, meaning we multiply the options) 2 out of 4) and multiplying them by the different options of values:
In order to count how many hands result in a flush, we do it the same way, but now, we have to choose 5 out of 13 cards, times 4 possible suits:
