Answer:
The number of
Fiction books = x = 2400 fiction books
Non fiction books = y = non fiction books
Step-by-step explanation:
Let the number of
Fiction books = x
Non fiction books = y
The libary has 4,000 books in total.
Hence: x + y = 4000........ Equation 1
The number of fiction books in a libary is %150 of the number of non-fiction books.
x = 150% of y
x = 150/100 × y
x = 1.5y
We substitute 1.5y for x in Equation 1
x + y = 4000
1.5y + y = 4000
2.5y = 4000
y = 4000/2.5
y = 1600 non fiction books
Solving for x
x = 1.5y
x = 1.5 × 1600
x = 2400 fiction books.
Therefore,
The number of
Fiction books = x = 2400 fiction books
Non fiction books = y = non fiction books
False.
The scale factor for 3 and 45 is 15.
45 / 3 = 15.
We know that 25 isn't even a whole number for the scale factor, because no number x 4 can equal 25 (whole numbers only).
25 / 3 = 6.33333
Probabilty = 12×(1/12)^3=1/144
5x-10x+ 2(3y-2)= 10y-5x + 4
Multiply 2 x 3y and by -2
5x-10x+6y-4=10y-5x+4
You get 6y-4
-5x+6y-4=10y-5x+4
Subtract 10x from 5x to get -5x
6y-4=10y+4
Add 5x to the -5x
6y=10y+8
Add 4 to the other side to get 8
-4y=8
Subtract 6y-10y to get -4y
-4y/-4=8/-4
Divide -4y and 8 by -4 to get y by itself and -2
Y=-2
