Answer:
10 days
Step-by-step explanation:
Jenny has read 50 pages and will read 15 each day.
The equation would be: 15x+50
Mark will read 20 pages daily.
The equation would be: 20x
In both equations x represents days.
You set both equal to each other because you want to know when they read the same amount of pages.
15x+50=20x
...you subtract 15x from both sides
50=5x
...and divide by five to get: 10 days
Answer:
C
Step-by-step explanation:
The standard form for the explicit formula of a geometric sequence is given by:
Where a is the initial term, r is the common ratio, and n is the nth term.
Our sequence is: 8, 4, 2, 1...
So, we can see that our initial term or a is 8.
Each subsequent term is half of the previous one. So, our common ratio is 1/2.
Let's substitute 8 for a and 1/2 for r to acquire:
So, our answer is C.
And we're done!
