Answer:
$2184
Step-by-step explanation:
The total number of "ratio units" in the ratio fiction : non-fiction is 3+5 = 8. The total number of fiction + non-fiction books is 832, so each ratio units must stand for 832/8 = 104 books.
Then the 3 ratio units of fiction books stand for 3×104 = 312 books. The total spent on fiction books is that number times the average price:
312 × $7 = $2184 . . . . total spent on fiction books
The answer is -8,-7,-5,-1,1,3,5

Answer:
x = (28 +- root -64) / (8)
Step-by-step explanation:
4x^2 -28x= -53 = 0
x = [-(-28)+- root (-28)^2 - 4 * 4 * 53] / 2 *4
x = (28 +- root 784 - 848) / (8)
x = (28 +- root -64) / (8)
