30 MINUTES
8 divided by 2 is 4
60 divided by 2 is 30 minutes
Answer:
Step-by-step explanation:
The equation for an arithmetic sequence is
where n is the position of the number in the sequence, a1 is the first number in the sequence, and d is the difference between the numbers in the sequence.
Our first number is 2, so a1 = 2; to get from 2 to 5 we add 3, to get from 5 to 8 we add 3. That means that d = 3. Filling in the standard form of the equation:
which simplifies to
and a bit more to
(which should tell you that arithmetic sequences are lines!)
Finding the 13th number simply requires that we replace n with 13 and solve:
so
Kim: 20.18
Sally: 17.39
Tina: 24.36
Zoey:25.09
X= 23+8y
X represents the total
23 represents the base price
8 represents the price per extra hour
Y represents how many hours extra
