2x - 9 = x

2x - x = 9

x = 9

Answer 2

Answer:

The correct answer is 9.

Step-by-step explanation:

2x – 9= x <----- Here is the original problem.

2(9) – 9 = 9 <----- Replace the variables.

18 - 9 = 9 <----- Simplify the multiplication.

Answers

Given:

A pizza with one topping costs $11. Each additional topping costs $2  more.

To find:

The recursive formula  and an explicit formula for the  situation.

Solution:

The sequence of costs of pizza is

11, (11+2), (11+2+2), ...

11, 13, 15, ... are in A.P.

Here,

First term: a=11

Common difference: d=2

Explicit formula of an A.P. is

[tex]a_n=a+(n-1)d[/tex]

where, a is first term and d is common difference.

[tex]a_n=11+(n-1)2[/tex]

[tex]a_n=11+2n-2[/tex]

[tex]a_n=9+2n[/tex]

Therefore, the explicit formula for the  situation is [tex]a_n=9+2n[/tex].

Recursive formula of an A.P. is

[tex]a_n=a_{n-1}+d[/tex]

Where, [tex]a_1[/tex] is first term and d is common difference.

[tex]a_n=a_{n-1}+2[/tex]

Where, [tex]a_1=11[/tex].

Therefore, the required recursive formula is [tex]a_n=a_{n-1}+2[/tex] where [tex]a_1=11[/tex].

Answers

Answer:

1. KLP + PLM = 180 degrees (straight line)

2. 3x + angle PLM = 180 degrees

3. angle PLM = 180 - 3x

4. PMN = P + PLM (Exterior angle)

5. 2x + 72 = x + 180 - 3x

6. x = 27

Step-by-step explanation:

1. Notice that angle KLP + angle PLM is a straight line, so KLP + PLM = 180 degrees (straight line)

2. angle KLP = 3x, so

3x + angle PLM = 180 degrees

3. angle PLM = 180 - 3x

4. PMN = P + PLM (Exterior angle)

5. 2x + 72 = x + 180 - 3x

6. 5 gives 4x = 108, so x = 27

Answer:

1. KLP + PLM = 180 degrees (straight line)

2. 3x + angle PLM = 180 degrees

3. angle PLM = 180 - 3x

4. PMN = P + PLM (Exterior angle)

5. 2x + 72 = x + 180 - 3x

6. x = 27

Step-by-step explanation:

ngl i didnt really get this i i kinda have a some what idea on what this is

The exterior angles of the triangle added to their corresponding interior angles equal 180 degrees by virtue of the sum of angles on a straight line.

As such the interior angles are

1. 180 - (x+ 3)

2. 180 - (2x+ 1)

3. 180 - (3x - 4)

Given that the sum of angles in a triangle is 180 degrees

180 - (x+ 3) +  180 - (2x+ 1) + 180 - (3x - 4) = 180

540 - 6x = 180

6x = 540 - 180

6x = 360

x = 60

The exterior angles are

x + 3 = 60 + 3 = 63

2x + 1 = 2(60) + 1 = 121

and

3x - 4 = 3(60) - 4 = 180  - 4 = 176

An Olympic-sized swimming pool holds 2,500,000 liters of water. How many gallons of water does an Olympic-sized swimming pool hold? Round your answer to the nearest tenth.

Answers

Answer:

The Olympic sized swimming pool hold 660501.9 gallons of water.

Step-by-step explanation:

Given that:

Water hold by an Olympic sized swimming pool = 2500000 liters

We know that;

1 gallon = 3.785 liters

Therefore,

We will divide the total number of water in liters by 3.785 to find the number of gallons.

Gallons of water in pool = [tex]\frac{2500000}{3.785}[/tex]

Gallons of water in pool = [tex]660501.9[/tex] gallons

Hence,

The Olympic sized swimming pool hold 660501.9 gallons of water.

George is standing at the end of a 72 ft shadow cast by a tall building. The angle of elevation to the top of the tall building is . What is the height of the building?

Answers

Answer:

Errm please where is the angle of elevation

I think there should be an angle before we can find the height of the building

The height of the building is 44.91 feet

What are trigonometric identities?

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Given that George is standing at the end of a 72 ft shadow cast by a tall building. The angle of elevation to the top of the tall building is 34.

Therefore we have;

tan ° A = opposite / adjacent

° A = 31;

The adjacent (height) = 72 ft

Now replacing;

tan 34 ° = x / 72

x = tan 34 ° ( 72)

x = 44.91

Therefore, the height of the building is 44.91 feet

C₂ = 50%

Solving for x:

We know that:

V₁C₁ = V₂C₂                                [Concentration formula]
