Answer:
B. x =1 , y = -5
Step-by-step explanation:
So, what we can do is to simply plug in all of the equations and see which one fits. Equation: x - y = 6
A. x =1 , y = -6
1 -(-6) = 6
1 + 6 = 7
A would be incorrect.
B. x = 1, y = -5
1 - (-5) = 6
1 + 5 = 6
Therefore, B would be correct.
Velocity=Distance/Time
Time(t)=Distance/Velocity

Answer : It is possible to form a triangle
Explanation : To form a triangle, sum of angles should be equal to 180
72 + 48 + 60 = 180 So, triangle is formed
Therefore the following statement is possible.
You should be able to set up a proportion between the sides something like (18+x)/x=(56+21)/56
Answer:
A, C, and D have been simplified correctly
