The expression which represents the amount of money Chloe owes is
amount = 14c - 3c. where 'c' is the cost per box.
What is a linear equation in one variable?
A linear equation is a one-variable equation of a straight line. The variable's only power is 1. Linear equations in one variable with the form an x + b = 0 are solved using basic algebraic operations.
Chloe ordered 14 boxes and per box 'c' dollars charged
Hence the total amount of money she has to pay is $14c
But 3 of the boxes are damaged so their price will be deducted from the total amount she was supposed to pay:
Now equation will become,
amount = 14c - 3c.
Hence, the expression which represents the amount of money Chloe owes is
amount = 14c - 3c. where 'c' is the cost per box.

What is the value of X
Answer:
x = 22/5; m∠TKW=m∠XHK = 15.2°
Step-by-step explanation:
Angles TKW and XHK are corresponding angles (as they lie on the same side of the traversal and on the bottom left side of their respective lines) and are thus congruent and equal.
By setting the two equations equal to each other, we can find the value.
After this, we can plug in x for any one of the equations and find the measure of both angles:
[tex]8x-20=3x+2\\8x=3x+22\\5x=22\\x=\frac{22}{5} \\\\TKW=8(\frac{22}{5})-20\\ TKW=\frac{176}{5}-20\\ TKW=\frac{76}{5}=15.2\\ TKW=XHK[/tex]

(pythagorean theorem mc) a tent pole that is 5 feet tall is secured to the ground with a piece of rope that is 13 feet long from the top of the tent pole to the ground. determine the number of feet from the tent pole to the rope along the ground. 12 feet 8 feet 25 feet 30 feet
Using the Pythagorean Theorem, the number of feet from the tent pole to the rope along the ground is 12 feet.
In the given question we have to determine the number of feet from the tent pole to the rope along the ground.
From the question;
A tent pole that is 5 feet tall is secured to the ground with a piece of rope that is 13 feet long from the top of the tent pole to the ground.
So the value of Hypotenuse(H) = 13 feet
Perpendicular(P) = 5 feet
Using the Pythagorean Theorem
H^2=P^2+B^2
Putting the value
(13)^2=(5)^2+(B)^2
169 = 25+B^2
Subtract 25 on both side, we get
B^2=169-25
B^2=144
Taking square root on both side, we get
B=12
Hence, the number of feet from the tent pole to the rope along the ground is 12 feet.

By using substitution method, x = 0, and y = -3 are the solutions of the given system of equations.
What is substitution method?
In order to solve a system of equations, the substitution approach is typically utilized in mathematics. The first equation involving the variable must be solved using this method before the variable's value is substituted in the second equation.
Consider the given system of equations
-5x - 3y = 9 ..(1)
4x - 18y = 54 ..(2)
From equation (1),
-5x = 9 + 3y
[tex]x =- \frac{9+3y}{5}[/tex] ..(3)
Plug the value of x in equation (2),
[tex]4(-\frac{9+3y}{5})- 18y = 54\\-36-12y-90y = 270\\ -36 - 102y=270\\102y = -36-270\\102y=-306\\y = -3[/tex]
Plug y = -3 in equation (3)
[tex]x = -\frac{9+3(-3)}{5} =-\frac{9-9}{5} =0[/tex]

Segment BD bisects angle ABC measure angle ABC equals 7x. The measure angle ABD equals 3x+25. Find the measurement of angle DBC
The measurement of angle DBC is 100°. It can be obtained by the properties of bisector of an angle and algebriac multiplication.
What is angle bisector?
An angle bisector is the ray or line segment that divides the angle into two equal parts.
Since the segment BD bisects angle ABC hence,
∠ABC = ∠ABD+∠DBC ..... (1)
Also, since segment BD bisects angle ABC hence,
∠ABD = ∠DBC
Use this fact in equation (1)
∠ABC = ∠ABD+∠ABD
∠ABC =2 ∠ABD
Now, substitute values and use algebriac multiplication.
7x = 2(3x+25)
7x = 6x+50
7x - 6x= 50
x=50
Now, substitute the value of x in the expression of ∠ABD.
∠ABD = 3x+25
∠ABD = 3(50)+25
∠ABD = 100
Now, since ∠ABD = ∠DBC hence, ∠DBC = 100.
Hence, the measurement of angle DBC is 100°.
