telo118 [61]

Answer: 29.35x+17.45y


Step-by-step explanation:

1. To solve this problem you must keep on mind the information given in the problem above. You know that:

- x represents the number of adult tickets purchased and y the number of child tickets purchased.

- The ticket cost for each adult is: $29.35

- The ticket cost for each child is: $17.45

2. Therefore, the total cost of the tickets is the sum of 29.35x (the number of adult tickets purchased by  the cost of the ticket for each adult) and 17.45y (the number of child tickets purchased by the cost of the ticket for each child):

29.35x+17.45y

Five balls are numbered 1 through 5 and placed in a bowl. Josh will randomly choose a ball from the bowl, look at its number and
andrezito [222]

Answer:

1/5

Each of the 5 balls has 5 possible combinations, as each one (1 - 5) can be paired with any of the 5. Therefore, the total number of combinations is 25.

For the product to be even, one of the balls has to be a 2 or 4. However, 2 multiplied by any number 1 - 5 is not greater than 10, so 2 is not an option. This means one of the balls has to be a 4.

There are only 3 numbers of 1 - 5 that, when multiplied by 4, are greater than 10. These are 3, 4, and 5.

This means that there are 5 combinations that work:

3 × 4 = 12

4 × 3 = 12

4 × 4 = 16

4 × 5 = 20

5 × 4 = 20

This means that 5 out of 25 combinations produce a result that is both even and greater than 10.

5/25 is then simplified to 1/5

Solve for y . <br><br> -9 = 3 / y<br><br> Simplify your answer as much as possible.
vivado [14]
You said that -9 = 3/y

Multiply each side by  y :  -9y = 3

Multiply each side by -1 :  9y = -3

Divide each side by  9 :  y = -3/9

Simplify the fraction :     y = -1/3
