For this case we have that the original price is $ 640. If this week is at $ 480 then the discount is:

$ 640- $ 480 = $ 160

Thus, the discount is $ 160.

We look for the percentage by making a rule of three:

$ 640 -------------> 100%

$ 160 -------------> x

Where "x" represents the discount percentage:

x = \frac {160 * 100} {640}\\x = \frac {16000} {640}\\x = 25

Thus, the discount percentage is 25%

Answer:

25%

Explain how you know that x^2-8x+20 is always positive. <br> Please help.
IRISSAK [1]

Answer:

if you rearrange to complete the square, you get (x^2-4)^2 +4

and seeing as anything squared will always be positive or zero, the lowest possible value for (x^2-4)^2 is 0, when x = 4

and 0 + 4 = 4, which is greater than 0, so positive

1/2r + 4= 3/4r - 3/2
ikadub [295]
<span>1/2r + 4= 3/4r - 3/2

1/2 = 2/4
3/2 = 6/4

re-write
2/4r + 4 = 3/4r - 3/4
2/4r - 3/4r = -3/4 - 4
-1/4r = -4 3/4
      r = (-4 3/4) / (-1/4)
      r =(-4 3/4) * (-4)
      r = 76/4
      r = 19</span>
