Answer:
213 books
Step-by-step explanation:
Paper books = $1.45 each
$ 1.45 = 1 paper book
$ 1 = 1/1.45 paper book
$98.6 = 98.6/1.45 paper books
$ 98.6 = 68 paper books
Hardback books = $ 2.25 each
$2.25 = 1 Hardbook
$1 = 1/2.25 hardbook
$ 328.10 = 328.10/2.25 hardbooks
$ 328.10 = 145.822 hard books
Number of books cannot be a decimal number, so the value has to be estimated to a nearer whole number.
$ 328.10 = 145 hard books
Total number of books bought = (145 + 68)books= 213 books (Answer)
F( x ) = ( x - 1 ) ( x + 2i )( x - 2i ), because the zeroes are 1, -2i, +2i ;
f( x ) = ( x - 1 )( x^2 - 4i^2 ) = ( x - 1 )( x^2 + 4 ) = x^3 - x^2 + 4x - 4 ;
Answer:
x = 10
Step-by-step explanation:
3x - 5 = 2x + 5
Both triangles equal 25
Subtract 2x → You get left with x
x -5 = 5
Add five... which leaves you with↓
x = 10
Then substitute x for 10
(3 · 10) - 5
25
(2 · 10) + 5
25
You know this is true because they equal each other.

Answer:
29/42

No. of blue candies = 13
T.T = 42
Probability that candy will not be blue= 13+13+3 = 29
= 29/42
