Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
- A completes
of all work; - B completes
of all work.
Hence, in 1 day both A and B complete 
of all work. A and B working together can do a work in 6 days. Then
Solve this equation:
If 
then 
that is impossible. So, B needs 15 days to complete the work alone.
An=3*(4^(n-1)) is the explicit
the recursive is <span>t_n = 4 * t_(n-1)</span>
58+37 is 122 since its double / by 2 and you get 61
Answer:
The line equation of the line is:
Step-by-step explanation:
Given the two points
Finding the slope between (0,3) and (8,0)
Therefore, the slope of the line: m = -3/8
Using the point-slope form of the line equation
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -3/8 and the point (0,3)
Add 3 to both sides
Simplify
Therefore, the line equation of the line is:
The answer is the 3rd one because if you do the star dot method you find that 1 is congruent to 2
