Answer:
They used 16.4 centimeters
Step-by-step explanation:
The best scale would probably be going by 10s. You should start at around 80 and go up to 160.
Like terms will have exactly the same variables
so 5a and 2a are like terms
examples :
3b and 4b are like terms
3b and 4a are not like terms
2a^2 + 3a^2 are like terms
2a and 3a^2 are not like terms
3ab and 4ba are also like terms...even though the variables are switched
6b^2a and 6a^2b are not like terms
Answer:
Option A) Inconsistent is correct
Step-by-step explanation:
Given equations are 
and 
Rewritting the equation y=5x+2 as below
5x-y=-2
Now multiplying the above equation into 2 we get

Now subtracting the equations (2) and (3)
10x-2y=12
10x-2y=-4
________

Therefore the given system of equations has no solution
Therefore it is inconsistent
Therefore given two lines are parallel. Two parallel lines never intersect, so the given system has no solution and is inconsistent.
Option A) Inconsistent is correct
