Well, each pizza is cut into 10 slices, that means both pizzas are 10+10 slices, or 20 slices, then they ate 14 of those 20 slices.
so they ate 14 out of 20, or 14/20, which simplifies to 7/10.
whenever you are dividing by 10 or 100 or 1000 you add that many zeroes behind the decimal so the answer is 0.009.
Answer:
aₙ = 207+9*(n-1)
Step-by-step explanation:
a1 = 207+9*(1-1) = 207
a2 = 207+9*(2-1) = 216
a3 = 207+9*(3-1) = 225
....
aₙ = 207+9*(n-1)
