Answer:
(V + W) * 5 = 175 boat traveling downstream
(V - W) * 7 = 189 boat traveling upstream
V + W = 35
V - W = 27
2 V = 62
V = 31 = speed of boat
2 W = 8
W = 4 speed of water
Upstream 7 * (31 - 4) = 189
Downstream 5 * (31 + 4) = 175
Answer:
The sum of interior angles in a triangle is 180°.
So we just have to add Al the angles and equate them to 189°
Step-by-step explanation:

Answer:
- 5x² + 6x + 6
Step-by-step explanation:
f(x) - g(x) - h(x)
= 3x + 5 - (4x² - 2) - (x² - 3x + 1) ← distribute parenthesis
= 3x + 5 - 4x² + 2 - x² + 3x - 1 ← collect like terms
= - 5x² + 6x + 6 ← in standard form
The answer to the question is A: 0.96 centimeters
of 1.6 is 0.64
If you subtract 0.64 from 1.6 you get 0.96,
of 1.6
