Is there any numbers or a picture
Answer:
40,320.
Step-by-step explanation:
We are asked to find the number of ways in which 8 books could be arranged on a shelf.
The 1st could be arranged in 8 ways. Since one place is filled, so 2nd book could be arranged in 7 ways.
Similarly, the 3rd book could be arranged in 6 ways as first two places are already taken. This process will go on.
So the 8 books can be arranged in
Therefore, 8 books could be arranged in 40,320 ways.
4.6y-y+4=y-1.2
We simplify the equation to the form, which is simple to understand
4.6y-y+4=y-1.2
We move all terms containing y to the left and all other terms to the right.
+4.6y-1y-1y=-1.2-4
We simplify left and right side of the equation.
+2.6y=-5.2
We divide both sides of the equation by 2.6 to get y.
y=-2
