120 = 2x + x
120 = 3x
120/3 = x

Since amy has twice as many cds, she would have 80 cds
Given, a parking lot charges $3 for first hour and $2 per hour after that.
So for t hours, the parking lot charges $3 for the first hour and after first hour there is
hours left.
So for
hours it will charge $2 per hour.
The charges for
hours = $
.
Total charges for t hours for one car = $
Now for the second car, it will charge 75% of the first car.
So the charges for second car
=$[
]
=$
There are 3 cars. That parking charges for the third car is also 75% of the first car.
So for third car the parking charges are same as for the second car.
Total parking charges for 3 cars
= $
= $
We have got the required answer here.
The correct option is option C.
Answer:
n=10
Step-by-step explanation:
You need n to be 10 because: y^20= (y^10)^2
First you need to find the slope of the line. So what you need to do is y^2-y^1 / x^2-x^1
(x^1, y^1) (x^2, y^2)
( -1, 7) ( 2, 10)
10-7/ 2- (-1)
3/3=1
slope is 1
I got 8 as the y intercept. Reason how is that I made a table. And what I did was go back instead of going forward.
x y
-1 7
0 8
1 9
2 10
The answer would be x= 1 y= x + 8 y=8 But the answer choice you listed for A. would not match up the 2 coordinate you gave. Make sure a. should be x= 1 y= x + 8 y=8, not -x y= 8-x y=8
