Answer:
2 10/16 or 2 5/8
Step-by-step explanation:
You can add the whole numbers first, so 1+1=2
Now add the remaining fractions: 5/16 +5/16=10/16.
2+10/16=2 10/16 or 2 5/8.
48 of the pizzas would be cheese because you divide 80 by 5 and get 16 then multiply that by 3 to get 48
My graphing calculator says g(4) = f(2).
The 4th selection, x=4, is appropriate.
