<h3>
Answer: 5</h3>
=================================================
Work Shown:
x^2 - 5x + 1 = 0
x^2 + 1 - 5x = 0
x^2 + 1 = 5x
(x^2 + 1)/x = 5 .... where x is nonzero
(x^2)/x + (1/x) = 5
x + (1/x) = 5
---------------
An alternative method involves solving the original equation using the quadratic formula. After you get the two roots x = p and x = q, you should be able to find that p + 1/p = 5 and also q + 1/q = 5 as well.
In this case,
p = (5 + sqrt(21))/2
q = (5 - sqrt(21))/2
Because a beach volleyball is a sphere, so the volume formula is V= 4pi r^3/r

The answer would be 26 because .1-4 rounds down, 5-9 rounds up
Grocery store : 2.80/8 = 0.35.....so its 35 cents per oz.----0.35(16) = 5.60 per lb
farmers market : 4.20/14 = 0.3...so its 30 cents per oz --- 0.30(16) = 4.80 per lb
5.60 - 4.80 = 0.80.....answer is : blueberries are 80 cents per pound less expensive at the farmers market
