Answer:
720 ways
Step-by-step explanation:
At first their are six books, that means that there are six different positions to put them. The first book to be placed would have 6 position, when the first book is placed, to place the second book there would be 5 position since one position has been used by the first book. After placing the second book, to place the third book there would 4 available position, and it follows this manner i.e for the fourth book 3 available position, for the fifth book 2 available position and for the sixth book, one available position.
Therefore the number of ways to arrange the books on the shelf from left to right = 6 × 5 × 4 × 3 × 2 × 1 = 6! = 720 ways
As the equation does not consists like terms we can only get x , y equations.
Step-by-step explanation:
Firstly, they are not like terms.
If the value to be is found is X then,
8x+5y=4
Now subtract 5y on both sides
8x+5y-5y=4-5y
here both positive 5y and negative 5y get cancelled
Now divide by 8
x=(4-5y)/8
If we need y value then,
subtracting both sides by 8x
5y=4-8x
Now dividing with 5 on both sides
y=(4-8x)/5 =>y=4/5 -8x/5
According to Y=mx+c
slope = m = 4/5
y-intercept = -8x/5.
135% of $60 = 135/100 * $60 = 27/20 * $60 = $81.
