R = 5n + 5w
r - 5w = 5n
r/5 - w = n
<span>The answer is B) 160
First find exterior angle
360 / 18 = 20
Interior angle = 180 - 20 = 160
</span>
<span>A. (-3, 5)
the equation is xy=-15
or x=-15/y
put y=5
x=-15/5
x=-3</span>
You have to find out what is the square root of 1.5 is which is <span>1.22474487139 by calculator to make sure of this, do answer squared and you will get 1.5</span>
