What property is m+7=7+m

Answer:

Equation: [tex]Height = \frac{75}{Area}[/tex]

Step-by-step explanation:

The question is incomplete as the dimension of the phone was not given.

However, the following explanation will guide you

Given

[tex]Volume = 75\ in^3[/tex]

Required

Determine the Height

Volume is calculated as thus;

[tex]Volume = Area * Height[/tex]

Substitute 75 for Volume

[tex]75= Area * Height[/tex]

Divide through by Area

[tex]Height = \frac{75}{Area}[/tex]

The above represent the equation to solve for Height

To solve for height, we need the dimension of the phone or the area.

Take for instance; the length and width of the phone is 5 by 5 inches;

The height would be:

[tex]Height = \frac{75}{5 * 5}[/tex]

[tex]Height = \frac{75}{25}[/tex]

[tex]Height = 3\ inches[/tex]

Answer:

[tex] \frac{2a}{(b1 + b2)} [/tex]

Step-by-step explanation:

A = 1/2(B1 + B2)h

2A = (B1 + B2)h

h = 2A/(B1 + B2)

Answer:

Step-by-step explanation:

Given the equation 2,900 = 250 + 132.5T, to get the solution of the equation, we will find the value of T as shown;

From 2,900 = 250 + 132.5T

subtract 250 from both sides;

2,900- 250 = 250 + 132.5T-250

2,650 = 132.5T

Divide both sides by 132.5

132.5T/132.5 = 2650/132.5

T = 20

Hence the solution to the equation tells us that the value of T is 20

-5 ≤ 1 - 2x < 9

Let's first break this down into two different inequalities.

1 - 2x ≥ -5

Subtract 1 from both sides.

-2x ≥ -6

Divide both sides by -2

x ≤ 3

Now, let's do the second inequality.

1 - 2x < 9

Subtract 1 from both sides.

-2x < 8

Divide both sides by -2

x > 4

let's combine each inequality to get our reduced compound inequality.

-4 < x ≤ 3

To plot this, put a hollow point at -4. A hollow point looks something like the letter o.

And put the second point at 3. This time, fill in the point so it looks whole.

Now, connect your points.

It should look something like this:

[tex]\text{Hello! :D}[/tex]

[tex]\boxed{\text{width = 13ft, length = 29ft}}[/tex]

[tex]\text{ Let the width = "w":}\\\\\text{Write an expression to represent the length in terms of "w":}\\\\l = 2w + 3\\\\\text{Formula of a rectangle: } \\\\P = 2l + 2w\\\\\text{Therefore:}\\\\84 = 2(2w + 3) + 2(w)\\\\84 = 4w + 6 + 2w\\\\84 = 6w + 6\\\\\text{Subtract 6 from both sides:}\\\\78 = 6w\\\\\text{Divide both sides by 6:}\\\\78/6 = 6w/6\\\\w = 13ft\\\\\text{Plug this value of "w" into the equations for the length:}\\\\l = 2(13) + 3\\\\l = 26 + 3\\\\l = 29ft[/tex]

Answer:

The family will not have enough money. They will have saved only 19,200

Step-by-step explanation:

The family will not have enough money. They will have saved only $19,200  is the best statement.

" Interest is defined as the amount of money which one has to pay while borrowing and charged while lending money."

According to the question,

Amount saved per month by Hartman family = $400

Amount need to pay fees after 4 years = $20,000

Total amount saved in 4years = 400 × 12 ×4

                                                 = $19200

Difference in amount needed = 20,000 - 19,200

                                                    = $800

Here it is not given that Hartman family has saved money in any bank.

Neither rate of interest is mentioned.

Hence, we conclude that the family will not have enough money. They will have saved only $19,200  is the best statement.

Answer:

B. Angles ABD and BAD

Step-by-step explanation:

The way that you tell which angles are congruent, are based on the angle marks. Angle A and C are congruent because they both contain 3 of the congruency marks, meaning they would equal the same degree. The answer is B because starting with angle BDA, B is your starting point, whereas D is the angle and A is the point you end on. With angle BAD, you start at point B and end at D, making angle A the one you're looking at. Because angle A contains 3 congruency marks, while angle B only contains one, this makes the two angles NOT congruent. Hope this helps. :)

Answer:

angles ABD and BAD

Step-by-step explanation:

The congruent angles match in the number of angle markings on the diagram.

45+4x=6x+5

45=2x+5

40=2x

20=x

x=20

Answer:

x = 20

45 - 5 =6x - 4x

40 = 2x

x = 40/2

x = 20

Answer:

x = 3

Step-by-step explanation:

Simplifying

4 + -7x = 1 + -6x

Solving

4 + -7x = 1 + -6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6x' to each side of the equation.

4 + -7x + 6x = 1 + -6x + 6x

Combine like terms: -7x + 6x = -1x

4 + -1x = 1 + -6x + 6x

Combine like terms: -6x + 6x = 0

4 + -1x = 1 + 0

4 + -1x = 1

Add '-4' to each side of the equation.

4 + -4 + -1x = 1 + -4

Combine like terms: 4 + -4 = 0

0 + -1x = 1 + -4

-1x = 1 + -4

Combine like terms: 1 + -4 = -3

-1x = -3

Divide each side by '-1'.

x = 3

Simplifying

x = 3
