Let x represent the number of pounds of $10.75/lb coffee used in the mix.
.. 10.75x +3.25(100 -x) = 5.65*100 . . . . . . total cost of coffee blend
.. x(10.75 -3.25) = 100*(5.65 -3.25) . . . . . .separate x-terms from non-x terms
.. x = 240/7.5 = 32

32 pounds of $10.75/lb coffee should be used
68 pounds of $3.25/lb coffee should be used

Divide the polynomials. Your answer should be in this form p(x)+k/ x-3 where p is a polynomial and k is an integer. x^2+4/x-3=

Makovka662 [10]

Answer:

x + 3 + $\frac{13}{x-3}$

Step-by-step explanation:

Using long division

x + 3 ← quotient

--------------------------

x - 3 | x² + 0x + 4

x² - 3x ↓

------------------------

3x + 4

3x - 9

-----------------------

13 ← remainder

Thus

$\frac{x^2+4}{x-3}$ = x + 3 + $\frac{13}{x-3}$
