Use the second one
<span>-8y=6</span>
To convert the value given above, we need a conversion factor to multiply. The conversion factor to be used here would be 0.5 since from conversion tables 1 up is equal to 0.5 pints. We calculate as follows:
8 cups (0.5 pints / 1 cups ) = 4 pints
Hope this answers the question. Have a nice day.
Using proportions, it is found that the boat can go 6 m/s in still water.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that:
- Down the river, the speed is v + 2.
- Up the river, the speed is v - 2.
He goes twice as fast down the river, hence:
v + 2 = 2(v - 2).
v + 2 = 2v - 4
2v - v = 2 + 4
v = 6.
The boat can go 6 m/s in still water.

At n = 2
a₂ = (-1)² + 3a₂₋₁ + 2
a₂ = 1 + 3a₁ + 2
a₂ = 1 + (3)(5) + 2
a₂ = 18
At n = 3
a₃ = (-1)³ + 3a₃₋₁ + 2
a₃ = -1 + 3a₂ + 2
a₃ = -1 + (3)(18) + 2
a₃ = 55
At n = 4
a₄ = (-1)⁴ + 3a₄₋₁ + 2
a₄ = 1 + 3a₃ + 2
a₄ = 1 + (3)(55) + 2
a₄ = 168
The first four terms are 5, 18, 55, 168
