Given:
The graph of two lines.
To find:
The slope of each line and check whether they are same or different.
Solution:
If a line passes through two points, then the slope of a line is:
From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:
The slope of first line is 10.
From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:
The slope of second line is 10.
Therefore, the slopes of both lines are same, i.e. 10.
The value of x is 55.
It is a 90 degree angle so you subtract 90 and 35 to get 55.
Answer:
The time taken by the four workers to paint the room is 1.5 hours.
Step-by-step explanation:
3 workers can paint a room in 2 hours
So, 1 worker can paint the same room in 6 hours.
Now the number of workers is 4.
So, the time in which the 4 workers can paint the same room is
= 6/4 = 1.5 hours
Answer:
-28-3x-4=2x+12+x
-32-3x=3x+12
6x=44
x=44/6=22/3
