Answer:
55.734 mph
Step-by-step explanation:
Let's call the wind speed x and the time of flight t.
Then, we can write the following equation, knowing that the distance is equal speed times time of flight:
910 = (350+x) * t
660 = (350-x) * t
If we isolate t in both equations and compare its value, we have that:
910 / (350+x) = 660 / (350-x)
(350+x)/(350-x) = 910/660
350 + x = 1.3788 * (350-x)
350 + x = 482.58 - 1.3788x
2.3788x = 132.58
x = 55.734 mph
whats the equation?
i need the equation in order to solve for x
Answer:
The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles
Step-by-step explanation:
We are given
Bethel Park is 28 miles directly west of Jeanette
10.3 miles directly south of Pittsburgh
We can draw diagram
we can see that this is triangle
so, we can use Pythagoras theorem
and we get

now, we can solve for x


So,
The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles
Answer:
<h2>
C) The system has no solutions</h2>
Step-by-step explanation:
3x + 2y =<u> 3
</u>
3x + 2y = <u>19</u>
Both left sides are the same, so the right sides cannot be different
