Answer:

x = 3

y = 6

Step-by-step explanation:

(-4x - y = -18)

2 (2x + 3y = 24)

-4x - y = -18

4x + 6y = 48

5 / 5y = 30 / 5

y = 6

______________________

-4x - (6) = -18

-4x - 6 + 6 = -18 + 6

-4x = -12

-4x / 4 = -12 / 4

x = 3

Here, Pages in books = Number of books * number of pages in one book

So, Pages of picture book = 10 * 25 = 250

So, Number of Total pages = 250 + 600 = 850

So, Option (D) is your answer! Hope this helps!!

10. Mr. Sanchez goes to the movies every 18 days. His brother goes to the
mestny [16]
90 days.

For this question you just need to find the least common multiple of 18 and 30. That can be found by first finding the prime factorization of each number. 18 = 2 * 3 * 3 and 30 = 2 * 3 * 5. Then you multiply the 2 * 3 * 3 * 5, you ignore the 3 from 30 because 18 has more 3s. The answer is 90.
