Answer:
-5
Step-by-step explanation:
Geometric sequences have common ratios.
You can see if a sequence is geometric by computing:
.
If you get the same result per consecutive pair, then there is a common ratio and the sequence is geometric.
Let's see:
So if this equations holds (if all 3 fractions equal the same thing), then is geometric and we have also have computed the common ratio.
The first fraction results in -250/50=-5.
The second fraction results in 50/-10=-5.
The third fraction results in -10/2=-5.
All three fractions are equal and so the equation holds so it is geometric and the common ratio is -5.
Answer:
First option
x = 9.1, AB = 16.5, CD = 14.1
Step-by-step explanation:
5 * x = 13 * 3.5
5x = 45.5
x = 9.1
AB = 3.5 + 13 = 16.5
CD = 5 + 9.1 = 14.1
Answer:
The absolute value of 5 is 5
Answer:
B
Step-by-step explanation:
the answer to your question would be B if you do multiply
number of reams= 6×8 =48
number of 2 weeks 48 reams can last= 48/5= 9.6
time 48 reams of paper can last= 9.6×2= 19.2 weeks
