Answer:
Arithmetic Sequence
Step-by-step explanation:
In Arithmetic sequence each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k.
1/7x+1/3x=1
3/21x+7/21x=1
10/21x=1
x=21/10 hour or 2 hours and 1 minute
Only two positive integers, 2 and 8, fit the description.
2 = 10 (base 2) = 2 (base 3)
8 = 1000 (base 2) = 22 (base 3)
Their sum is 10.
A. 18
the equation is y=1/4x+1
