It is best to use mental math with some equations (5x5 or something that is easy enough that work does not have to be shown 10 dived by 5
Answer:
D. x = 22.5
Step-by-step explanation:
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.
Answer:
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.
Step-by-step explanation:
Answer

Step by step explanation
Let the points be A and B
A ( 5 , 1 ) ⇒ ( x₁ , y₁ )
B ( -3 , -5 )⇒ ( x₂ , y₂ )
Now, let's find the distance between theses two points:
Distance = 
Plug the values

Calculate

Evaluate the power

Add the numbers

Write the number in exponential form with a base of 10

Reduce the index of the radical and exponent with 2

-------------------------------------------------------------------------------
The distance formula is used to determine the distance ( d ) between two points. If the co-ordinates of the two points are ( x₁ , y₁) and ( x₂ , y₂ ) , the distance equals the square root of x₂ - x₁ squared + y₂ - y₁ squared.
