rewona [7]

Answer:

4032 different tickets are possible.

Step-by-step explanation:

Given : At a race track you have the opportunity to buy a ticket that requires you to pick the first and second place horses in the first two races. If the first race runs 9 horses and the second runs 8.

To find : How many different tickets are possible ?

Solution :

In the first race there are 9 ways to pick the winner for first and second place.

Number of ways for first place - ^9C_1=9

Number of ways for second place - ^8C_1=8

In the second race there are 8 ways to pick the winner for first and second place.

Number of ways for first place - ^8C_1=8

Number of ways for second place - ^7C_1=7

Total number of different tickets are possible is

n=9\times 8\times 8\times 7

n=4032

Therefore, 4032 different tickets are possible.

Alicia earned d dollars baby-sitting. Her friend earned twice as much. You earned $2 less than Alicia's friend earned. Write an
Semenov [28]

Answer:

Total = \$5d - 2

Step-by-step explanation:

Represent Alice with A, her friend with F and you with Y.

From the question, we have:

A = \$d

F = 2 * A --- Twice as much Alice means 2 times Alice's earnings

Y = F - 2 --- 2 less than her friend

Required

Determine the total amount

A = \$d

Substitute \$d for A in F = 2 * A

F = 2 * \$d

F = \$2d

Substitute \$2d for F in Y = F - 2

Y = \$2d - 2

The total amount is calculated by adding the earnings of Alice, her friend and you

Total = A + F + Y

Total = \$d + \$2d + \$2d - 2

Total = \$5d - 2

<em>Hence, the total earnings is 5d - 2</em>

nadezda [96]
3(2D-1)-2D = 4(D-2)+5
6D-3-2D = 4D-8+5
4D-3 = 4D-8+5
4D-3 = 4D-3
4D = 4D-6
0 = -6
