Answer:

Price of bracelet =  $(25 + 5c)

Step-by-step explanation:

As given,

A bracelet = 1 chain + Number of charm selected by customer

Also given,

Price of chain = $25

Price of each charm = $c

As,

we have to write equation for a bracelet with 5 charm

So,

Price of bracelet = Price of 1 chain + Price of 5 charm

As

Price of 1 charm = $c

⇒Price of 5 charm = $5×c = $5c

∴ we get

Price of bracelet = $25 + $5c = $(25 + 5c)

Answer:

4cm

Step-by-step explanation:

Given data

L=(2x+3)

W=(x-1)

P=28cm

A= L*W

A= (2x+3)*(x-1)

open bracket

A= 2x^2-2x+3x-3

collect like terms

A= 2x^2+x-3

P= 2L+2W

P= 2*(2x+3)+2(x-1)

P= 4x+6+2x-2

collect like terms

P= 6x-4

but p= 28

28= 6x-4

28-4= 6x

24= 6x

x= 24/6

x= 4cm

Hence x= 4cm

Answer:

multiplication

Step-by-step explanation:

7 x e = f

Answer:

If a number and letter are together, it means it is a multiplication problem. It is the same thing as 7 x e.

Step-by-step explanation:

We don't know what e is because there isn't a number given to us to solve the problem, so we say 7 x e = 7e, but the equation tells us that 7e = f, so 7 x e is equal to f which means 7e is equal to f.

Let me just give a number to e. Let's say e is 5

7e = f

We already know 7e is the same thing as 7 x e, so let's rewrite it

7 x e = f

We will change e to 5 and multiply the numbers together

7 x 5 = f

Now multiply 7 x 5

35 = f

If 35 is equal to f, that means the value of f is 35, so f = 35 ( I don't know if this makes sense lol)

But let's now take the original equation and assume f is 42

7e = f

Remember, 7e is 7 x e, so rewrite your equation

7 x e = f

Now we will change the f to 42

7 x e = 42

To get e, we will have to think about what multiplies by 7 to get 42. We will have to change this to division. We will divide 42 by 7

42÷7 = 6

That means e is 6. Now let's write the equation with changing e to 6

7 x 6 = 42

7 times 6 is 42, so we will multiply that

42 = 42

Now we have equal answers. Of course, 42 is equal to 42

Overall I'm trying to say 7e = f

I'll solve this again, so you won't have to go back up.

7e = f

7 x e = f

f = f

I hope this makes sense lol

Answer:

Because one letter represents an endpoint and the other doesn't.

Step-by-step explanation:

Ray AB starts at endpoint A and goes through point B and then on, indefinitely.

Ray BA starts at endpoint B and goes through point A and then on, indefinitely.

They 'point' in opposite directions.

Answer:

1) Obtuse angle

2) Obtuse angle

3) Acute angle

You can do 4 and 5. I will give you a hint that acute angles are less than 90 degrees and obtuse angles are more than 90 degrees. And if it is a straight line it is 180 degrees.

6) Angle KLM, MLK, Obtuse angle, and angle 5.

7) Angle DCB, BCD, Obtuse angle, and angle 5.

You can do 8. I will give you a hint that the letters will start from end-middle-end and it can be opposite. If getting confused then look what I did. On muber 6, my I typed angle KLM and angle MLK. Both of them are same but look on how I typed. Also while naming angles, they will be in capital.

Hope this helps, thank you !!

Express as an equation

Represent the number of words with w and the minutes with m.

In 1 minute, Jordan types 40 words.

In m minutes, Jordan will type 40m words.

Answer:

The conclusion supported by the diagram is;

(A)  [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

Step-by-step explanation:

The question is examines the theorem that two transversals cut by three or more parallel lines are proportionally divided by the transversals

The given parallel lines are;

Line CD, line BE, and line line AB

The given transversals are;

Line AC and line DF

Therefore, by the above three or more parallel lines cutting two transversal theorem, we have;

BC/AB = ED/FE, BC/DF = AB/FE, CA/AB = DF/FE

From BC/AB = ED/FE, we find the inverse of both sides to get;

[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{1}{\dfrac{ED}{FE} }[/tex]

[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{AB}{BC} \ and \ \dfrac{1}{\dfrac{ED}{FE} } = \dfrac{FE}{ED}[/tex]

[tex]\therefore \ \dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

The correct option is [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

Answer:

The third triangle

Step-by-step explanation:

The Exterior Angle is the angle a side of a shape and a line extended from the side next to it.

So for example, the first picture shows an exterior angle because a line was extended and it forms an angle with the triangle's side.

The second picture is still an exterior angle because the angle is formed with an extended line and the triangle's side.

The third photo shows an angle formed between a random line and the triangle's side. This is not an exterior angle because the angle is not formed with any side's extension.

The fourth photo is an exterior angle because it shows the angle being formed with an extension of a line from the triangle and a side of the triangle.

Answer:

12 ft

Step-by-step explanation:

Note that you have a right triangle here, with hypotenuse 13 ft, and base 5 ft.  Using the Pythagorean Theorem, we find the height of the upper tip of the ladder as follows:

(13 ft)^2 = y^2 + (5 ft)^2.  Then y^2 = 144 ft^2, and y =height= 12 ft
