Answer:
x = 26 2/3 ~= 26.67
Step-by-step explanation:
Set up a proportion comparing like things.
It's easier to see if you write the small triangle separately.
See image.
I've done the calculation twice. Just look at the one that makes the most sense to you Obviously, it works out the same either way.
Answer:Except -1 for all real values of k given the equations has a unique solution.
Step-by-step explanation:
Except -1 for all real values of k given the equations has a unique solution.
Explanation:
Compare given linear pair of equations
(3k+1)x+3y-2 = 0 ----(1)
(k²+1)x+(k-2)y-5=0 ----(2)
with
----(2)
----(3)
we get ,
and
\* Given linear equations have unique solution *\
=> 3k(k-2)+1(k-2)≠3k²+3
=> 3k²-6k+k-2≠3k²+3
=> 3k²-5k-3k²≠3+2
=> -5k ≠ 5
Divide each term by (-5) , we get
=> k ≠-1
Therefore,
Except -1 for all real values of k given the equations has a unique solution.
Answer:
$5367.54
Step-by-step explanation:
9000 = P(1 + .03/12)^207*
9000 = P×1.676744643
P = 5367.54
*207 = 12 x 17.25
