Answer:
It has to be A because its the only one that makes sense
Step-by-step explanation:
<u>c) 3, 6, 9 12</u> is NOT a geometric progression
<h3>Further explanation
</h3>
Geometry sequences are series of numbers that have a constant ratio
or can be interpreted:
Each number is obtained by multiplying the previous number by a constant
The sequence can be:
a, ar, ar², ar³, ... etc.
Can be formulated
where:
a is the first term, and
r is the common ratio
So we have to see the series has the same ratio or not
a. 
b. 
c.
d.

Answer:
x = -3
Step-by-step explanation:
6x - 9 = -27 (Given)
6x = -18 (Add 9 on both sides.)
x = -3 (Divide 6 on both sides.)
−1/3⋅(8 1/7)
change 8 1/7 to an improper fraction
8 1/7 = (7*8 +1)/7 = 57/7
-1/3 * 57/7
-57/21
21 goes into 57 2 times with 15 left over
-2 15/21
divide top and bottom of the fraction by 3
-2 5/7
Choice B
Take 60 minutes and times that by 60 to find your seconds. (s)
Next, take 240 times 3 to find your feet. (f)
Then, take your feet divided by seconds. (T)
f/s =T
