What is the distance in the image below?
2 answers:
Since the segment is completely horizontal we need not to use formula for computing the length of a segment in 2D euclidean space.
Instead we can simplify the problem to a single dimension, only considering the x-coordinates of the endpoints of the segment.
The x-coordinates are -5 and 3.
Subtracting and applying absolute value yields the answer,
.
Hope this helps.

Answer:
Both plans last for 1.25 hours (1 hour 15 minutes)
Step-by-step explanation:
Let x hours be the time needed for plan A and y hours be the time needed for plan B.
On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.
On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.
Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:
Therefore,
