Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27
C
20% increase
$50 + 20% = $60
∛(1/8 - <em>x</em>) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - <em>x</em>))³ = (-1/2)³
1/8 - <em>x</em> = -1/8
2/8 = <em>x</em>
<em>x</em> = 1/4
Slope intercept form is y = mx + c.
<em>(where m is the slope, and c is the intercept - hence slope intercept form)</em>
So all you have to do is rearrange the inequality to have y by itself.
-6x + 3y > - 45 <em>(add 6x to both sides)</em>
3y > - 45 + 6x <em>(divide both sides by 3)</em>
y > - 15 + 2x <em>(put the 2x infront of the - 15) </em>
y > 2x - 15

Answer:
y > 2x - 15
