5x - 11x = 15 + 9
-6x = 24
x = -4
Answer:
Greater than
Step-by-step explanation:
(<em>C</em> × 9/5) + 32 = <em>F</em>

Answer:
68
Step-by-step explanation:
Alright, so to find how many pages that can be had, we have to replace P with the amount of money Jennifer has. This is because P is the price of one book, and we want to find the number of pages (x) we can buy for a book price of 62.10 or less.
62.1 = (20 + 0.5x) + 0.15(20 + 0.5x)
62.1 = 20 + 3 + 0.5x + 0.075x
62.1 - 23 = 0.575x
39.1 = 0.575x
39.1/0.575 = x
x = 68
Therefore, in order to buy a book that costs 62.10, the book must have 68 pages.
Step-by-step explanation:
3x + 1
=3x + 1
this is because a variable X is attached to the 3 so it makes the 3x and the 1 unlike
therefore you can not add them.
