Answer:
D. x = 7 and m∠LMN = 120°Step-by-step explanation:
Since MO bisect angle LMN, the angles formed are congruent:
∠LMO≅∠NMOSubstitute values and solve for x:
13x - 31 = x + 5313x - x = 53 + 3112x = 84x = 7Find the value of ∠LMN:
m∠LMN = 2*m∠LMOm∠LMN = 2(13*7 - 31) = 120°Correct option is D
Here,
MO is bisect of the [tex]\angle{LMN}[/tex],
SO,
[tex]\angle{LMO}[/tex]=~[tex]\angle{NMO}[/tex]
According to the question,
[tex]\bold{ 13x-31=x+53 }[/tex]
[tex]\bold{ 13x-x=53+31 }[/tex]
[tex]\bold{12x=84 }[/tex]
[tex]\bold{x=\dfrac{84}{12} }[/tex]
[tex]\bold{x=7 }[/tex]
Now we find the value of [tex]\angle{LMN }[/tex]
so,
[tex]\angle{LMO}=2×\angle{NMO }[/tex]
[tex]\bold{ 2×(13×7-37) }[/tex]
[tex]\bold{2×(91-31) }[/tex]

Answer:
There is one solution (4,0)
Step-by-step explanation:
First, we will try to solve this system of equations.
I will rearrange 2x-5y=8 to isolate -5y.
The new equation would be 5y=2x-8.
Now we will add
2x -8 = 5y
with
-2x+8=5y
We get 0 = 10y
Divide by 10 and we get y = 0.
Now that we know the value of y, lets solve for x.
2x-8=5(0)
2x-8=0
Add 8
2x=8
Divide by 2 to isolate x
x = 4.
x=4 and y=0
The solution is (4, 0)

Answer:
2 angles that meet at an endpoint
As per the image, we can say that 2 rays that meet at an end point.
Option 2 is correct.
What is a ray?A ray is a part of the line having one fixed point and the other point does not have an end.
As per the image, we can say that 2 rays that meet at an end point.
Because 2 rays meet at a point and another side arrow is shown in image.

Complete the explanation of how you can adjust your answer without weighing the liquid again. Then give the weight in kilograms. If necessary, round your answer to the nearest tenth.
only right anwres
Answer:
7.7 pounds = 3.5 kilograms
Step-by-step explanation:
Given that,
Weight of a gallon of liquid = 7.7 pounds
We need to find weight in kilograms.
We must know the relation between pounds and kilograms and it is as follows :
1 kilogram = 2.20 pounds
or
1 pounds = (1/2.2) kilograms
7.7 pounds = (7.7/2.2) kilograms
= 3.5 kilograms
Hence, 7.7 pounds is equal to 3.5 kilograms.

True or false ???
Answer:
The statement 'V(x) is a function'' is False.
Step-by-step explanation:
Let us make the table from the given mapping
x y
0 0
5 2
5 1
10 2
15 3
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
If we observe the table, it is clear that x = 5 is repeated twice. It means the input x = 5 is duplicated.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, V(x) is not a function.
Hence, the statement 'V(x) is a function'' is False.

What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = number is more than negative five
Let the number be represented as n

Find the measure of each angle in the problem: complementary angles with measures 4x and 5x-18 degrees
Answer:
42 degrees and 48 degrees
Step-by-step explanation:
If they are complementary, that means they add up to 90 degrees, so
4x + 5x - 18 = 90,
Solving,
9x - 18 = 90
add 18 to both sides
9x = 108
divide both sides by 9
x = 12
Now, to find the angle measures of each you have to substitute x = 12 into both angles.
4x --> 4 * 12 = 48 degrees
5x - 18 --> 5 * 12 - 18 --> 60 - 18 --> 42 degrees
If the rate of inflation is 3.4% per year, the future price pt (in dollars) of a certain item can be modeled by the following exponential function, where t is the number of years from today.
pt = 2500(1.022t)
Find the current price of the item and the price 10 years from today.
Answer:
The answer is "3107.75".
Step-by-step explanation:
[tex]\text{Rate of inflation} = \frac{3.4 \%}{year}[/tex]
[tex]\to p(t)= 2500 (1.022)^t[/tex]
when t= 0
[tex]\to p(0) = 2500(1.022)^0[/tex]
[tex]= 2500 \times 1\\\\= \$ 2500[/tex]
When t=10
[tex]\to p(10)=2500(1.022)^{10}[/tex]
[tex]= 2500 \times 1.2431\\\\= 3107.75[/tex]
