Answer:
246 physics books
186 biology books
Step-by-step explanation:
1) there are 432 total books
2) there are 60 more physics books than biology books
3) 432 - 60 = 372
4) 372 divided by 2 = 186
5) 432 - 186 = 246
Check:
246 + 186 = 432
246 - 186 = 60
hope this helped :)
:) Well, I dunno about anyone else but this question makes my head spin!
Answer:
GK = 9x-5
Step-by-step explanation:
GK = GH +HJ + JK
= (GJ - HJ) + (HJ) + (HK - HJ)
= (4x-3-x) + (x) + (6x-2-x)
= 3x-3 + x + 5x-2
= (3x+5x+x)+(-3-2)
GK = 9x-5
X= -a/f = z/mf + g/mf
-a is over f
+ z over mf
+ g over mf
Answer:
Clearly from 1 to 15 we can only have the sum 6,9,12 and 15 to be divisible by 3.
Now meaning we have 4! ( 4 factorial) which implies 4x3x2x1= 24 .
We have 24 ways to pick distinct integers that are divisible by 3.
Step-by-step explanation:
The first thing you need to do is to look for numbers that are divisible by 3. Then you take its factorial
