Answer:
5040 ways
Step-by-step explanation:
That is 7 books.
So the number of ways is factorial 7 , written 7!.
= 7*6*5*4*3*2*1
= 5040 ways
Rewrite the equation: 2y=x-6, y=x/2-3, so slope is 1/2 which is also the slope of the parallel line.
It will have the equation y=x/2+a where a is found by plugging in the given point: 4=-1+a, so a=5.
Therefore y=x/2+5. (This can also be written 2y=x+10 or x-2y+10=0)
Answer:

Answer:
$18
Step-by-step explanation:
- I multiply the tax by the pretax price of the meal, and I get 8% * x
- I multiply the tip by the pretax price of the meal, and I get 20% * x
- I make an equation, and make sure to add the original x
- 2/25x + 1/5x + x=23.04
- 32/25x=23.04
- x=18
- Therefore, the pretax price of the meal is $18
