Point K is between Points J and L. KL = 9x + 2, KJ = 5x 8 and JL= 12x. Find KL.
The length of KL is 35 units
How to determine the length KL?The given parameters are:
Point K is between Points J and L. KL = 9x + 2, KJ = 5x 8JL= 12x.The above means that
JL = JK + KL
So, we have
5x - 8 + 9x + 2 = 12x
Evaluate the like terms
2x = 6
Divide by 2
x = 3
Substitute x = 3 in KL = 9x + 2,
KL = 9 x 3 + 8
Evaluate
KL = 35
Hence, the length of KL is 35 units

Ashton is hosting a banquet. He plans to spend $400, plus or minus $50, at a cost of $25 per guest. Solve |25x-400|= 50 to find the maximum and minimum number of guests. If there can be up to 7 guests at each table, what is the minimum number of tables Ashton should reserve so that every guest has a seat?
Answer: The maximum is 18 and the minimum is 14. He should rent at least 3 tables.
Step-by-step explanation:
When there can be up to 7 guests at each table, the minimum number of tables that Ashton should reserve so that every guest has a seat will be 3 tables.
How to calculate the value?It should be noted that the expression given is illustrated as:
|25x-400|= 50
25x = 50 + 400
25x + 450
Divide
x = 450/25
x = 18
The maximum number of guests will be 18.
The minimum number will be:
25x = 400 - 50
25x = 350
Divide
x = 350/25
x = 14
The minimum number is 14.
Therefore, when there can be up to 7 guests at each table, the minimum number of tables that Ashton should reserve so that every guest has a seat will be:
= 18 / 7
= 3 tables approximately.

step 1: Check which squared numbers can be multiplied by another number to get 38.
Start with these numbers: 4, 9, 16, and 25
Step 2: Testing out the numbers
√25 × __ = 25 can't be divided by 38
√16 × ___ = 16 can't be divided by 38
√9 × ____ = 9 can't be divided by 38
√4 × ____= 4 can't be divided by 38
Step 3: Answer
After trying the square root numbers that could possibly work with √38 none work; which means √38 can't be simplified. So the answer is √38

O2(2+3) = 6 – 2
O2(x + 3) = 2x+6
O2(x + 3) = 6x
O2(2 + 3) = 2r/3
Answer:
Option B==========================
The distributive property is:
a(b + c) = ab + acApply this to the options:
A) 2(2 + 3) = 2*2 + 2*3 = 4 + 6, not matching, no;B) 2(x + 3) = 2x + 2*3 = 2x + 6, matching, yes;C) 2(x + 3) = 2x + 6, as above, not matching, no;D) 2(2 + 3) = 4 + 6, not matching, no.Answer:
b) 2(x + 3) = 2x + 6
Step-by-step explanation:
The formula we refer to is,
→ a × (b + c) = (a × b) + (a × c)
The option obeys distributive law is,
→ 2 × (x + 3) = (2 × x) + (2 × 3)
→ 2(x + 3) = 2x + 6
Hence, option (b) is correct.

Name all the line segments that are skew to line segment BF
The line segment that is skew line to line segment BF is CD.
Skew line:
Skewed lines are two lines that are not parallel to one another, and neither do they intersect. Only dimensions greater than two-dimensional space can have skew lines. They must be non-coplanar, which means that they must exist on several planes. Two lines in two-dimensional space can either intersect or run parallel to one another. Therefore, skew lines are impossible in 2D space.
The line segment AB is perpendicular to the line segment BF which means it is not the skew line to line segment BF
The line segment CD is not parallel and not perpendicular to the given line segment BF which means it is a skew line to the given line segment BF.
Therefore, The line segment that is skew line to line segment BF is CD.

Sharon's annual percentage yield (APY) to the nearest hundredth of a
percent is; 2.02%
How to calculate annual percentage yield (APY)?
We are told that;
Amount Deposited = $8000

B = $8161.61
Interest is;
I = $8161.61 - $8,000
I = $161.61

Calculate the distance between Point A (-8,-2) and Point B(6,-1) Leave the answer in radical form.
the distance between Point A (-8,-2) and Point B(6,-1) in Radical form= [tex]\sqrt{197}[/tex]
Distance formula:
The distance between two points formula uses the coordinates of two points in space. In coordinate geometry, the distance between two points can be calculated using the distance formula, present in a two-dimensional or three-dimensional space. The distance formula for two points is also an application of the Pythagoras theorem
the distance formula is used to find the distance between any two points when we already know the coordinates. The points could be present alone on the x-axis or y-axis or on both axes.
Let us consider, that there are two points say A and B in an XY plane. The coordinates of point A are (x1,y1), and of B are (x2,y2). Then the formula to find the distance between two points PQ is given by:
AB=[tex]\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }[/tex]
Note: If the coordinates of two points P and Q are such that, (x1, 0) and (x2, 0), the distance between PQ will be given by:
PQ = |x2 – x1|
the distance between point origin O(0,0) and P(x,y) is given by:
OP = √((x2 – 0)² + (y2 – 0)²)
OP = √((x2)² + (y2)²)
or simply,
OP = √(x² + y²)
Solution :
where x and y are coordinates of points other than the origin.
Given :
(x1,y1) = (-8,-2)
(x2,y2)= (6,-1)
Solution:
[tex]d=\sqrt{x^{2} +y^{2} } \\d=\sqrt{(6+8)^{2} +(-1+2)^{2} } \\d=\sqrt{14^{2}+1^{2} } \\[/tex]

Kadeesha is going to a carnival that has games and rides. Each game costs $2.50 and each ride costs $4.75. Kadeesha spent $48.75 altogether at the carnival and the number of games she played is twice the number of rides she went on. Write a system of equations that could be used to determine the number of games Kadeesha played and the number of rides Kadeesha went on. Define the variables that you use to write the system.
Taking into account the definition of a system of linear equations, the system of equations that could be used to determine the number of games Kadeesha played and the number of rides Kadeesha went on is:
[tex]\left \{ {{2.50G+4.75R=48.75} \atop {G=2R}} \right.[/tex]
where G is the number of games Kadeesha played and R is the number of rides Kadeesha went on.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values of the unknowns give the solution proposed in both equations.
System of equations in this caseIn this case, a system of linear equations must be proposed taking into account that:
G: number of games Kadeesha played.R: number of rides Kadeesha went on.On the other hand, you know:
Each game costs $2.50 and each ride costs $4.75. Kadeesha spent $48.75 altogether at the carnival. The number of games she played is twice the number of rides she went on.So, the system of equations to be solved is
[tex]\left \{ {{2.50G+4.75R=48.75} \atop {G=2R}} \right.[/tex]
Among the different existing methods to solve the system of equations, it is decided to solve it using the substitution method. This method consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, substituting the second equation in the first one you get:
2.50×2R+4.75R=48.75
Solving:
5R+4.75R=48.75
9.75R=48.75
R= 48.75÷ 9.75
R= 5
Remembering that G=2R, you obtain that G=2×5= 10
In summary, the system of equations that could be used to determine the number of games Kadeesha played and the number of rides Kadeesha went on is:
[tex]\left \{ {{2.50G+4.75R=48.75} \atop {G=2R}} \right.[/tex]
where G is the number of games Kadeesha played and R is the number of rides Kadeesha went on.
Finally, the number of games played is 10 while the number of rides she went on is 5.

equilateral? Explain how you know.
The ΔVZW is Equilateral Triangle .
Equilateral Triangle is defined as the triangle in which all the three sides of the triangle are equal.
For Example ; if a triangle ABC has lengths AB=2cm , BC=2cm and CA=2cm then the triangle ABC can be called as an equilateral triangle as all sides have same length i.e. 2cm .
In the question ,
From the diagram, we have the radius of all the circles are of equal length ,
Since the radius of all the circles are equal in length , their diameter will also be equal in length .
We can see from the diagram that VZ , ZW and WV are the diameters of the circles , So they will be equal in length ,
which means VZ = ZW = WV.
In triangle VZW the sides VZ , ZW and WV are of equal length , hence the triangle will be an Equilateral Triangle.
