Step-by-step explanation:
The common ratio is a constant found in geometric sequences, denoted r in the equations for geometric sequences, when any term is divided by the term preceding it. In this case the common ratio is: 147/21=21/3=7=r So 7 is the common ratio.
Answer:
C
8
5 ( x - 3 ) + 2x = 41
5x - 15 + 2x = 41
5x + 2x - 15 = 41
7x - 15 = 41
7x = 41 + 15
7x = 56
x = 56 / 7
x = 8
it will take 25 hours
Step-by-step explanation: add 10 and 15
The slope would be 7
it could also be represented as m = 7
