Answer:

C  a1= -2

    an = an-1 +3

Step-by-step explanation:

an = -2+ (n-1)3

What is the first term?  Let n=1

a1 = -2 + 0*3

a1 = -2


The difference between the  terms is +3  (coefficient on (n-1))

The second term is the first term +3

The third term is the second term plus 3

The next term is the previous term +3

so an = an-1+ 3

A cab in NYC charges you $1.25 a mile and a flat fee of $4 to ride in the cab. A cab in Chicago charges you $0.75 a mile but a f
Vikentia [17]

Answer:

After 4 miles driven by cab the amount would be same in both cities.

Step-by-step explanation:

Let the number of miles be 'x'.

Given:

In NYC

Flat fee of cab = $4

Per mile charge = $1.25

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in NYC = 4+1.25x

In Chicago

Flat fee of cab = $6

Per mile charge = $0.75

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in Chicago = 6+0.75x

Now we need to find number of miles driven so that the amount could same in both cities.

Total cab charges in NYC = Total cab charges in Chicago

4+1.25x=6+0.75x

Combining like terms we get;

1.25x-0.75x=6-4\\\\0.5x=2

using Division Property we will divide both side by 0.5 we get;

\frac{0.5x}{0.5} =\frac{2}{0.5} \\\\x=4

Hence After 4 miles driven by cab the amount would be same in both cities.

The cost of 6 CDs are $12, $13, $20, $20, $12.50 and $18.50. What is the median?
sattari [20]
If we put the numbers in order, it would be 12, 12.50, 13, 18.50, 20, 20 we can see the middle numbers would be 13 and 18.50. if only one number is wanted as the median, then we can do (13+18.50) divided by 2 and get 15.75.

lyudmila [28]
