Answer:
64/7 i think
Step-by-step explanation:
whole trip ---- x km
day1 , hiked 1/8 of train, leaving (7/8)x
day 2 , hiked 4/7 of (7/8)x leaving
(3/7)(7/8)x or (3/8)x to be hiked
day3 :
(1/3)(3/8)x + 8 = x
x/8 + 8 = x
times 8
x + 64 = 8x
7x = 64
the trail is 64/7 km
check:
day 1 they hiked (1/8)(64/7)
leaving (7/8)(64/7) = 8 km
day2, hiked 4/7 of remaining, leaving
(3/7)(8) or 24/7 km
day 3
(1/3)(24/7) + 8
= 64/7
yeahhh!
Answer:
He would save 9,730$.
Step-by-step explanation:

Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that
We have the a² and the b² in the equation 
, and we <em>almost </em>have a 2ab in the equation 
. To get that 2ab, we can simply double both sides of the first equation to get 
. From there, we'll add the first two equations together, giving us the summed equation
And since , we can equivalently say that
