Answer:
17
Step-by-step explanation:
8.5 / 0.5
First simplify
x-4y-8=3/4-10y
add 10y both sides and add 8
x+6y=8+3/4
times 4 both sides
4x+24y=32+3
4x+24y=35
5y-3(6-7/8)=5x-4y+3
add 4y both sides
9y-3(6-7/8)=5x+3
distribute
9y-18+21/8=5x+3
minus 5x both sides
9y-5x-18+21/8=3
add 18 to both sides and minus 21/8 both sides
9y-5x=21-21/8
times 8 both sides
72y-40x=147
72y-40x=147
so we got
24y+4x=35
72y-40x=147
multiply first equation by -3 and add to 2nd
-72y-12x=-105
72y<span>-40x=147 +</span>
0y-52x=42
-52x=42
divide both sides by -52
x=-21/26
sub back
24y+4x=35
24y+4(-21/26)=35
using math
y=497/312
the solution is
It should be 5/13 because the opposite angle from D is 12, which you would use if you are looking for sine. But, since you are looking for cosine, it is adjacent over hypotenuse. Therefore leaving you with 5/13, since your hypotenuse is always your longest side and the adjacent is the other side from the one opposite of the angle.
Answer:


Step-by-step explanation:
Since we believe it
The number sequence is that those which can be described as
and that is not ending and recurring. Figures that are unreasonable are also the ones, that are not
and therefore are non-ending, non-recurring.
The number sequence is 
Rational amount since it is classified as
.
is really a rational number.
is a real function, since it does not end but repeats it.
The rational number 
Unreasonable number
