There were 100 pizzas sold at Romeo's Pizzeria on Tuesday. A large pizza costs $16 and a small pizza costs $11. If $1,550 worth of pizzas were sold in all, how many small pizzas were sold?

Step-by-step explanation:

Let number of large pizzas be l and number of small be s.

Then we have equations:

From the first equation, we get l = 100 - s and substitute in the second equation:

Number of small pizzas is 10

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
