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.
Answer:
The coordinates of point b are (-5,5).
Step-by-step explanation:
Given:
Point a is at (-7,-7) and m is at (-6,-1).
So, to find the coordinates of point b.
Let a (-7,-7) be , m (-6,-1) and b
.
Now, putting the formula to get the coordinates:
⇒
So, here we will make two equations to find the value of :
multiplying both sides by 2
⇒
⇒
And, now same method for getting the value of .
multiplying both sides by 2
⇒
⇒.
The value of =
.
Therefore, the coordinates of point b are (-5,5).
