Answer:
the boat travel one way = 2 x 14.16 = 28.32 miles
Step-by-step explanation:
the return trip only takes 1.7 miles (?) ... is it 1.7 hours (?)
the boat travels 2.5 miles (per hour ?) faster downstream
I calculate it on the assumption of my guess stated above ...
X: represent the boat speed / hour
distance one way = 2X
and Distance also = 1.7 * (x + 2.5 ) on return
2x = 1.7 x + 1.7 * 2.5 = 1.7x + 4.25
0.3 x = 4.25
x = 14.16
the boat travel one way = 2 x 14.16 = 28.32 miles

Answer:
-23 = x
Step-by-step explanation:
-(-9) = 9
The thing with double negatives is that they form a plus sign, so that is really a POSITIVE nine. Therefore you do the inverse to find <em>x</em>: -14 - 9 = -23.
