Answer:
-38.85 or -24
Step-by-step explanation:
What I do is start with the brackets along with the rest of the numbers involved
2(10) is basically 2 x 10= 20
-39 + 3/20
3/20 = 0.15
-39 + 0.15 = -38.85
Unless if 3/2(10) has 3/2 as a fraction, the answer would be -24
Answer:
175 pages
Step-by-step explanation:
Let's call 'd' the number of days before the deadline, and 'n' the total number of pages of the book.
We have the following equations:
(1) 
--> if we multiply the number of pages per day (25) times the number of days (d), we get the total number of pages of the book (n)
(2) 
--> he reads 8 pages more per day (so, 25+8), for a number of days equal to (d-2) (d is the deadline), and he reads a total of n-10 pages (because only 10 are left)
We can substitute (1) into (2) and we find:
So, the deadline is 7 days, and from eq.(1) we find the number of pages in the book:
