The definition, theorem, or postulate that justifies the statement "If 2KL=KL+MN, then KL=MN" is the Segment Addition Postulate.
The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation:
AB + BC = AC
The definition, theorem, or postulate that justifies the statement "If 2KL=KL+MN, then KL=MN" is the Segment Addition Postulate.
The Segment Addition Postulate states that if three points A, B, and C are collinear and B is between A and C, then AB + BC = AC.
In this case, 2KL=KL+MN is equivalent to KL+KL=MN+KL, which satisfies the Segment Addition Postulate since KL is between MN and 2KL. Therefore, KL=MN

Answer:
a. subtraction property of equality
Step-by-step explanation:
Answer:
a = 7/2
Step-by-step explanation:
Step 1: Write equation
6a - (2a + 4) = 11 - 3(a - 2)
Step 2: Solve for a
The variable 'a' in the given equation is 3. First, simplify both sides of the equation, then isolate 'a' by adding and subtracting the same terms on both sides. Finally, divide to find 'a'.
The first step to solve the equation 6a-(2a+4)=11-3(a-2) is simplifying both sides. On the left-hand side, distribute the negative sign into the parenthesis, resulting in 6a - 2a - 4. Simplifying this gives 4a - 4. On the right-hand side, distribute the negative 3 into the parenthesis, resulting in 11 - 3a + 6. Simplifying this gives -3a + 17.
So, the simplified equation is 4a - 4 = -3a + 17. To isolate the variable a on one side, add 3a to both sides to get 7a - 4 = 17. Then add 4 to both sides to get 7a = 21. Finally, divide both sides by 7 to get a = 3.

Answer:
53.85
Step-by-step explanation:
Answer:
I'm pretty sure it's:
5x5x5x5x5x5x5x5x5 x 2x2
5x + 8y = 775 and x + y =125
5x – 8y = 125 and x + y = 775
5x + 8y = 775 and x – y = 125
5x – 8y = 125 and x – y = 775
Let x represent the number of quick washes and let y represent the number of premium washes.
1. One quick wash costs $5, then x quick washes cost $5x.
One premium wash cost $8, then y premium washes cost $8y.
They made $775 from a combination of quick and premium washes, then in total they made $(5x+8y) that is $775. The first equation is
5x+8y=775.
2. They had washed 125 cars, x cars by quick wash and y cars by premium wash, that is x+y in total. Then tha second equation is
x+y=125.
Only option A represents the situation.
What is the measure of angle C?
Enter your answer in the box.
°
Answer:
∠C = 62°
Step-by-step explanation:
GIVEN :-
TO FIND :-
FACTS TO KNOW BEFORE SOLVING :-
PROCEDURE :-
As ABCD is a cyclic quadrilateral ,
∠B + ∠D = 180°
Putting the values of x gives :-
∠A = (2×40 + 38)° = 118°
∠B = (3×40)° = 120°
∠D = (40 + 20)° = 60°
Also,
∠A + ∠C = 180°
⇒ ∠C = 180° - 118° = 62°
