-2x=-18/3​

Answers

Answer 1
You would just decide both sides by 2.

-x = -9/3 ⇨ -3
Since both numbers are negative, the product becomes a positive.
x=3

Answer:

Factor out a:

[tex]a\left(4+9b\right)=K[/tex]

Divide both sides by: [tex](4+9b)[/tex]

Answers

Answer:

the measurements must be incorrect because when you solve it, it is obvious that 6x is not a 90 degree angle and 3x is not 45 degrees.

Step-by-step explanation:

Answer:

x=20

Step-by-step explanation:

Ques5) x value is 20 because 3x+6x=180

=>9x=180

=> x=180/9

=> x=20

Ques6) 6x= 6*x which is equal to 6*20=120

Ques7) 3x=3*x which is equal to 3*20=60

This is correct because 120+20=180 which is a straight angle given in the question. Hope this helped, Thank you.

Find the value of x in the triangle shown below help please!!

Answers

Step-by-step explanation:

Hey there!!

It 's so simple.

You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)

So,

77° + 31° + x = 180°

x + 108° = 180°

x = 180° - 108°

Therefore the measure of angle x is 72°.

Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, what is Stephanie's age?​

Answers

Answer: Stephanie is 15

Step-by-step explanation:

because you can do 24 divided by 2 which equals 12 then add three to 12 and you get 15.

you're welcome! plz lmk if i'm wrong XD

Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, then Stephanie's age is 15 years.

To find Stephanie's age, we need to follow the given information that her age is 3 years greater than half of her sister's current age.

First, we find half of her sister's age: Half of 24 = 24 / 2 = 12

Next, we add 3 years to half of her sister's age: 12 + 3 = 15

Therefore, Stephanie's age is 15 years.

Age can be used in mathematical equations and word problems to solve for unknowns or to establish relationships between different quantities. For example, age-related math problems might involve scenarios such as Finding someone's age given their birth year and the current year,  Calculating the average age of a group of people and Determining the age difference between two individuals based on their birth years.

The Hartman family is saving $400 monthly for Ronald's college education. The family anticipates they will need to

The family will not have enough money. They will have saved only $16,000.
O The family will not have enough money. They will have saved only $19,200.
The family will likely have enough money. They will have saved $16,000 and have accumulated interest.
O The family will likely have enough money. They will have saved $19,200 and have accumulated interest.

Answers

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.

What is interest?

" 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.

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.

4-7x=1-6x can someone please solve and show the work :)

Answers

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'.

The volume of the cell phone is 75 cubic centimeters. Write and solve an equation to find the height of the cell phone. Round your answer to the nearest tenth

Answers

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]
