Answer:
Judy is 16 years old
Step-by-step explanation:
J = Judy's age
A = Adams age
J = 2A
Six years ago (subtract 6 from the ages)
(J-6) = 5*(A-6)
Distribute
J-6 = 5A - 30
Substitute J = 2A
2A -6 = 5A -30
Subtract 2A from both sides
2A-2A -6 = 5A-2A -30
-6 = 3A -30
Add 30 to each side
-6+30 = 3A-30+30
24 = 3A
Divide by 3
24/3 = 3A/3
8 = A
Adam is 8 years old now
We need to find Judy's age
J = 2A
J = 2*8
J = 16
Judy is 16 years old

Step-by-step explanation:
Assuming that the diamater is 16 inches, then yes because the pizza is twice as big, it should be twice as much.
But because it is not stated in the question that it is 16 inches in <u><em>diamater,</em></u> I will not say yes. It could be 16 inches in radius, curcumfrience, or area.
