Answer:
9) 5y
10) 10 x² - 4
11) 2a ∧5 + 5b
12) 8m +4n + 2
Step-by-step explanation:
9) 8 y - 3 y = 5y
10) 6x² + 4 (x²-1) = 6x²+ 4x²-4 = 10x²-4
11) 4a∧5 - 2a∧5 +4b + b = 2a∧5 +5b
12) 8m +14-12+4n = 8m+4n+2
Answer:
what are you supposed to be doing
Answer:
+5
Step-by-step explanation:
So you can see the 5 pattern, so you add 9+5= 14 which goes in the middle square and 14+5=18 in the left square
Now between 18 and 11 it is 7 so you subtract 7 which equals 4 then - 5= -1 then -5= -6
These are the answers lol can I get brainliest
Percentage of pages of a book read by Katie = 32%
Total number of pages of the book read by Katie = 80
Let us assume the number of pages that the book has = x
Then
(32/100) * x = 80
32x = 80 * 100
32x = 8000
x = 8000/32
= 250
So the book has a total of 250 pages in it.
Then
The number of pages that Katie still needs to read = 250 - 80
= 170
So Katie needs to read 170 more pages in the book.
