For this you divide the total spent by the total number of pizzas...
16.50/ 3 = $5.50 per pizza.
Let the number of deluxe that Pacific has be x
the number that Caribbean has will be (x+18)
the number that Mediterranean has will be (3x-25)
total b=number of deluxe in the 3 ships will be:
x+(x+18)+(3x-25)
5x-7=928
5x=928+7
x=935/5
x=187
Hence the Pacific has 187, Caribbean has 187+18=205, Mediterranean has (3*187-25)
=534
Answer:

Step-by-step explanation:

Set up equation
Step 1: Simplify

Step 2:Multiply by conjugate

Step 3:Simplify

We can reduce this and we must make the imaginary number and real number serpate equations.

Reduce each by 2

6-4/2x=y
Hope this helps and pls tell me if im right
