Answer:
2135
Step-by-step explanation:
610 divided by to is 305 so the half of the hours the plane flys 305 miles.
610 times three equals 1830.
1830 plus 305 equals
<span>C: y = 6x+20
Let's construct our own equation and then see if one of the available options matches.
"During her storefront shift, she sells her pizzas at a rate of 6 pizzas per hour"
This sounds like the equation should be:
6x
Since for every hour (represented by x) she sells 6 pizzas. Now we have:
"During her delivery shift, she sells 20 pizzas per night."
Notice that there's no mention of anything per hour. If she does the delivery shift, she sells a constant 20 pizzas. So let's modify our equation to:
6x + 20
And since we want it in slope intercept form, let modify a bit further:
y = 6x + 20
Now look at the available options and see if there's anything that matches. And there is ... Option C is a perfect match.</span>

your answer
The answe is the second option
Since a calculator is involved in finding the answer, it makes sense to me to use a calculator capable of adding vectors.
The airplane's ground speed is 158 mph, and its heading is 205.3°.
_____
A diagram can be helpful. You have enough information to determine two sides of a triangle and the angle between them. This makes using the Law of Cosines feasible for determining the resultant (r) of adding the two vectors.
.. r^2 = 165^2 +15^2 -2*165*15*cos(60°) = 24975
.. r = √24975 ≈ 158.03
Then the angle β between the plane's heading and its actual direction can be found from the Law of Sines
.. β = arcsin(15/158.03*sin(60°)) = 4.7°
Thus the actual direction of the airplane is 210° -4.7° = 205.3°.
The ground speed and course of the plane are 158 mph @ 205.3°.
