Answer:
18.98 pounds
Step-by-step explanation:
Let 'e' represent the number of pounds of expensive candy Ellen should use. Then 27-e is the number of pounds of less expensive candy. Her total cost is ...
1.45(27 -e) +3.74e = 27(3.06)
(3.74 -1.45)e = 27(3.06 -1.45) . . . . subtract 1.45(27)
e = 27(3.06 -1.45)/(3.74 -1.45) = 27(1.61/2.29) ≈ 18.98
Ellen should use about 18.98 pounds of the expensive candy.

<em>Additional comment</em>
We showed the solution this way because it is the generic solution to any mix problem. The fraction of the mix that is the highest-value contributor is the ratio of the difference between the mix value and the lowest contributor to the difference between contributors. Here, that fraction is ...
(3.06 -1.45)/(3.74 -1.45) = (1.61/2.29)
A.
well, to find the perimeter of a rectangle, it is 2(length+width)
using this, the perimeter of the tennis court is 2(2x+6+x)=2(3x+6)=6x+12
the perimeter of the basketball court is 2(3x-14+1/2x+32)=2(2 1/2x+18)= 5x+36
B.
the difference is subtraction, so it'd be 6x-12-(5x+36)
C.
width is 2x+6
2x+6=36
2x=30
x=15
tennis: 15 by 36
basketball: 3*15-14= 31
1/2*15+32= 39.5
31 by 39.5
(x + 7)(x + 4)
(x² + 4x + 7x + 28)
x² + 11x + 28
A straight line of sun, that ends at a certain point.
