Answer:
1) x = 17, line a parallel to line b
2) x = 18, line a parallel to line b
Step-by-step explanation:
If line a parallel to line b then (10x - 40) + 50 = 180
Solve for x
10x - 40 + 50 = 180
Combine like terms
10x + 10 = 180
10x = 170
x = 17
x = 17, line a parallel to line b
-------------------------------------------------
If line a parallel to line b then 5x - 16 = 74
Solve for x
5x - 16 = 74
5x = 90
x = 18
x = 18, line a parallel to line b
How is B right?
I think the 'most right' answer is D. Non of these are correct?...

good luck! have a nice day!
Answer:
$13
Step-by-step explanation:
First, find how much she put into the bank:
84 - 45 = $39
Then, multiply this by 2 to find how much she made, because this was half of the money she got:
39(2) = 78
Then, divide this by 6 to find how much she makes a day:
78/6 = 13
= $13
A) The shortest possible distance will be traveled if he moves straight from one side of the bank to the next, without any diagonal movement. Thus, he should steer southeast in order to counter the flow of the river from the east and also move towards his destination in a straight line.
b) The x-component of this wind can be calculated using:
Wx = 6cos(45)
Wx = 4.24 km/hr
This is greater than the opposing flow of the river from the east. Therefore, should row in a direction due south west to counter the wind's force as well as move towards his destination.
