Answer:
4 4/5 miles
Step-by-step explanation:
We want to multiply 4/5 * 6
4/5 * 6/1
24/5
We need to change this back to a mixed number
5 goes into 24 4 times (4*5 = 20 with 4 left over)
4 4/5 miles
Answer:
a(2) = -9
Step-by-step explanation:
It looks like you want the 2nd term in the arithmetic sequence defined by the recursive formula ...
- a(1) = -13
- a(n) = a(n -1) +4
Using the formula with n=2, we have ...
a(2) = a(1) +4
a(2) = -13 +4 . . . . substitute the value of a(1)
a(2) = -9
