Answer:

x = a^2 b

defon

Answer:

x = (2600/4000) × 100%

x = 0.65 × 100%

x = 65%

Step-by-step explanation:

The percentage equation that can be used to find the percent of books that are fiction can only be found where the number of fiction books is known and the total number of books available is known as well.

Given;

Number of fiction books = 2,600

Number of books = 4,000

let the percent of books that are fiction be x

x = (2600/4000) × 100%

x = 0.65 × 100%

x = 65%

Travka [436]

Answer:

x = 25/9 or 2.777777778

4(2-x) = 5x - 17

8 - 4x = 5x - 17

<u>    +4x   +4x</u>

8 = 9x - 17

<u>+17      +17</u>

25 = 9x

25/9 = x

x = 2.777777778 or 25/9
