Answer:
2a + 3b = 5
b = a - 5
Step-by-step explanation:
2a + 3b = 5
b = a - 5
You can write this another way:
2a + 3(a-5) = 5 ( I added the second formula in the first one )
Now you gotta factor out:
2a + 3a - 15 = 5
Here im gonna do plus 15
2a + 3a = 20 ==> 5a = 20
Now if you divide by 5, you get: a = 4
Now you can fill in the second formula again
b = a - 5 (ill fill this in now)
b = 4 - 5 = -1
So, this makes:
a = 4 , b = -1
Answer:
- Railway lines are example of parallel lines
- The floor and the walls of a room are example of perpendicular lines
- Two roads crossing at a signal can be termed as example of intersecting lines
Step-by-step explanation:
The lines can be related in following three ways
- Lines can be parallel
- Lines can be perpendicular
- Lines can be intersecting at an angle other than 90.
Now three real life examples of above three scenarios are described below:
- Railway lines are example of parallel lines
- The floor and the walls of a room are example of perpendicular lines
- Two roads crossing at a signal can be termed as example of intersecting lines
1 and 8 should be the answer I believe.
X = fraction 1 over 12
x = fraction 1 over 3
x = 3
x = 12
The given choices are the successive steps to solve the question :fraction 1 over 6x = 2
of which the last choice is the solution.
