Answer:
30 seconds
Step-by-step explanation:
Find the least common multiple of 6 and 15.
First, write the prime factorizations.
6 = 2 × 3
15 = 3 × 5
The LCM is the product of each distinct factor.
LCM = 2 × 3 × 5
LCM = 30
They flash together at the same time every 30 seconds.
Answer:

Step-by-step explanation:
To find recursive formula in a geometric sequence, you need to first find the common ratio, 'r', between the numbers in the given data set. From the data set given, it appears that the previous number is multiplied by
so, r =
.
Recursive formula involves two other variables:
the
term in the sequence
=the term before the
term
So, the final formula is: 
Answer:
57 years old
Step-by-step explanation:
If two-thirds of a woman's age is 38, then:
(2/3)x = 38
Multiplying both sides by 3/2 to solve for x will give us her age:
3/2)(2/3)x = (3/2)*38
x =57
She is 57 years old.

Answer:
Slope is 2/3
Step-by-step explanation:
(-3,-7) (9,1)
m = (y2-y1)/(x2-x1)
m = (1 + 7)/ (9 + 3)
m = 8/12
m = 2/3
