Answer:
I think 144.44 is the answer
Answer:
x=3, y=9
Step-by-step explanation:
5x-2y=-3
4x-2y=-6
Then:
solve for y:
-2y=-6-4x
y=3+2x
Substitute y into either equation:
4x-2(3+2x)=-6
4x-6-4x=-6
-6=-6, use other equation
5x-2(3+2x)=-3
5x-6-4x=-3
x-6=-3
x=3
then:
y=3+2(3)
y=9
Answer:
Latest time for start hiking = 4:57 PM
Step-by-step explanation:
Given:
Time of sunset = 9:26 P.M
Time taken for hiking = 3 hours and 3 minutes (03:03)
Time taken for set up = 1 hour and 26 minutes (1:26)
Find:
Latest time for start hiking
Computation:
Latest time for start hiking = Time of sunset - Time taken for set up - Time taken for hiking
Latest time for start hiking = 9:26 - 1:26 - Time taken for hiking
Latest time for start hiking = 8:00 PM - 03:03
Latest time for start hiking = 7:60 - 03:03
Latest time for start hiking = 4:57 PM
4n/4n-4 × n-1/n+1
= 4n(n-1)/(4n-4)(n+1)
= (4n^2 - 4n)/(4n^2 + 4n - 4n-4)
= (4n^2 - 4n)/(4n^2 - 4)
= 4(n^2 - n)/4(n^2 - 1)
=(n^2 - n)/(n^2 - 1)
