Answer
If only {2y(z-1)} is being divided by two:

9x+9+yz-y

If whole equation is divided by two:

9x+9+2yz-2y over 2

Explanation: In the first instance, you can cancel out the 2 in the numerator and denominator, which leaves you 9(x+1) + {y(z-1)}. You can then simplify to get 9x+9+yz-y

In the second instance, you distribute 9 to what is inside the parentheses, and get 9x+1. You then distribute 2y to what is inside the parentheses within the brackets and get 2yz-2y. You are then left with 9x+9+2yz-2y over 2

Answer:

B. Every 16 minutes, 22 more pizzas were set out on the buffet.

Step-by-step explanation:

At 11:00 am, x would be equal to 0, and there would be 15 pizzas on the buffet line. Then, every 8 minutes, 11 more pizzas are added to the buffet line. So in 16 minutes, 22 pizzas will be added to the buffet.

$\frac{16}{8} =2\\(11)(2) = 22$
