32.50,
<span>45.50 - 39 = 6.50 (the cost of one movie channel) </span>
<span>39 - 6.50 = 32.50 (the cost of cable without any movie channels) </span>
<span>Proof </span>
<span>32.50+6.50+6.50 = 45.50 </span>
Make the denominator into 10x:
5x/10x +20/10x=x(x+4)/10x
5x+20=x(x+4)
5x+20=x²+4x
x²-x-20=0
(x-5)(x+4)=0
x=5 or -4
the third choice is correct.
