Elaine is 28 years older than Carly. Elaine is x years old. Carly is y years old. Which set of equations shows this situation? *
O x = y + 28, y = x + 28
x = y + 28, y = x - 28
x = y - 28, y = x + 28
O x = y - 28, y = x - 28

1680 possible pizzas

Step-by-step explanation:

Pizza contains 2 different meat and 3 different vegetables.

If there are 5 meats and 8 vegetables, the customer can select any one of 3 types of crust.

Total number of ways to select meat = 5C2

nCr = n! /(n-r)! r!

5C2 = 5! / (5-2)!2!

= 5! / 3!2!

= 10

Total number of ways to select vegetables = 8C3

= 8!/(8-3)!3!

= 8! / 5!3!

= 56

Total number of pizza choice that can be made = 3 * 5C2 * 8C3

= 3*10*56

= 1680 possible pizza
