Can you possibly help me on my recent question?
Answer:
4 books
Step-by-step explanation:
The cost for one used = $2.27
The question requires you to find the number of books that could be purchased with $10
Let assume the cost for a single used book to be $ t
If you have $ x in your pocket then the number of books you can purchase with $ x will be;
number of books= $ x/ $t.............................(a)
Applying this expression to the question;
$t= $2.27
$ x= $10
number of books = $10/$2.27 = 4.405 = 4 books
THE ANSWER IS THE COMMON DIFFERENCE IS -7.2 (first answer)
PLEASE MARK BRAINLIEST :)
A = x^2 + 6x - 27 A = x^2 + 9x - 3x - 27 A = x(x+9)-3(x+9) A = (x+9)(x-3) A = lw l = (x+9) w =(x-3)
