Answer:
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Step-by-step explanation:
Let x = Courtney's walking speed
then
(x + 1) = Brandi's walking speed
:
Time = Distance/speed
Brandi walks 6.5 mi time = Courtney walks 5 mi time
6.5/x + 1 = 5/x
Cross multiply
6.5x= 5(x+1)
6.5x= 5x + 5
6.5x - 5x = 5
1.5x = 5
x = 5/1.5
x = 3.33 mph is Courtney's walking speed
Note that:
(x + 1) = Brandi's walking speed
3.33mph + 1 = 4.33mph
Therefore,
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Answer:
English please?
Step-by-step explanation:
...........
4 / -16 = -1/4. (also -1/4 = -1/4).
The general form of the sequence is:
a, ar, ar^2, ar^3....
Where r is the ratio: 1/4, and a is first term: -16.
You can see each term is just ar^n where n is the term number, starting where the first term n=0.
So the general formula would be:
-16(-1/4)^n
