Answer:
13
Step-by-step explanation:
We're trying to find the distance between points X and Y. Or the distance of X-Z plus Z-Y.
Lets find the distance of X-Z
6-2=4
Now lets find the distance of Z-Y
15-6=9
Now we add the distances
4+9=13
Answer:
$3
Step-by-step explanation:
Original price - Discounted price
= $15 - ($15 × 80%)
= $15 - ($15 × 80/100)
= $15 - ($1200/100)
= $15 - $12
= <u>$</u><u>3</u>
So, the sale price is $3

Answer:
120
Step-by-step explanation:
First, you want to find the third angle
to do that you 180-33+87=60
x=60
since x and y are on a straight line, to find y would be 180-x
180-60=120
y=120
Let <em>w</em> be the wind speed and <em>p</em> the plane's speed in still air.
Flying against the wind, the plane has velocity
<em>p</em> - <em>w</em> = 390 mi/h
and flying with it, it has
<em>p</em> + <em>w</em> = 470 mi/h
Add the two equations together to eliminate <em>w</em> and solve for <em>p</em> :
(<em>p</em> - <em>w</em>) + (<em>p</em> + <em>w</em>) = 390 mi/h + 470 mi/h
2<em>p</em> = 860 mi/h
<em>p</em> = 430 mi/h
Subtract them to eliminate <em>p</em> and solve for <em>w</em> :
(<em>p</em> - <em>w</em>) - (<em>p</em> + <em>w</em>) = 390 mi/h - 470 mi/h
-2<em>w</em> = -80 mi/h
<em>w</em> = 40 mi/h
