Answer: x is equal to 1

Step-by-step explanation:

The solution x = -30/7 is the value of the unknown number that satisfies the statement "eighteen more than 7 times a number is -12".

This question is incomplete, the complete question is:

Eighteen more than 7 times a number is -12, find the unknown number.

Given that, eighteen more than 7 times a number is -12.

Let's use "x" to represent the unknown number.

From the given information, we can use algebra to translate this sentence into an equation.

We start by using "7x" to represent the product of 7 times "x", and adding 18 to it:

7x + 18

Then, we set this expression equal to -12, since that's what the sentence told us the expression is equal to:

7x + 18 = -12

To solve for "x", we can first subtract 18 from both sides:

7x + 18 - 18 = -12 - 18

7x = -30

Then, we can isolate "x" by dividing both sides by 7:

7x/7 = -30/7

x = -30/7

Therefore, the value of the unknown number is x = -30/7.

One of the objects is made up of two separate quarters of a circle, each with a diameter of 1 inch.

On the other hand, the second object is one half-dollar coin with a diameter of 1.2 inches.

We will use the formula of the area of a circle that is : A = πr²

Where A is the area of the circle.

π is the constant value (3.14)

r is the radius of the circle.

Let's calculate the area of 2 quarters each with a diameter of 1 inch.

The radius will be half of the diameter.

So, the radius is 1/2 inch for each quarter of the circle.

A = πr²A = π × (1/2)²A = π × 1/4A = 0.7854 square inches.

The total area of both quarters will be = 2 × 0.7854 square inches

The total area of both quarters = 1.5708 square inches

Now, let's calculate the area of the half-dollar coin with a diameter of 1.2 inches.

The radius will be half of the diameter.

The radius of the half-dollar coin = 1.2 / 2 = 0.6 inch

A = πr²A

  = π × 0.6²A

The equation of the line parallel to y = (1/3)x + 4 and passing through (-6, 1) is y = (1/3)x + 3.

To find the equation of a line parallel to y = (1/3)x + 4 and pass through the point (-6, 1), we can use the fact that parallel lines have the same slope. The slope of the given line is 1/3, so the slope of the parallel line must also be 1/3.

Now we have the slope (m = 1/3) and a point on the line (-6, 1), so we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Plugging in the values, we get:

y - 1 = (1/3)(x - (-6))

Simplifying, we get:

y - 1 = (1/3)x + 2

Adding 1 to both sides, we get the final equation:

To find the percentage of the original amount that Dylan has remaining on his gift card, we can divide the remaining amount by the original amount and then multiply by 100 to express it as a percentage.

The original amount on the gift card was $20.00, and the remaining amount is $0.06, so the percentage of the original amount that Dylan has remaining on his gift card is:

($0.06 ÷ $20.00) x 100% =

0.003 x 100% =

0.3%

Therefore, Dylan has 0.3% of the original amount remaining on his gift card.

When using the empirical rule and you have a mean of 10 and a standard deviation of 1, approximately 68% of values fall between 9 and 11.

The empirical rule is also known as the three-sigma rule, which states that the values under a normal distribution curve are given by:

Approximately 68% of values fall within one standard deviation from the mean

Approximately 95% of values fall within two standard deviations from the mean

Approximately 99.7% of values fall within three standard deviations from the mean

To solve the problem, we have to calculate how many standard deviations the given values are from the mean:

Lower value = 9Mean = 10

Upper value = 11

Standard deviation = 1

Now, calculate the z-scores:

Lower z-score = (9 - 10) / 1 = -1

Upper z-score = (11 - 10) / 1 = 1

The values between 9 and 11 are within one standard deviation from the mean, so we use the first part of the empirical rule:

Approximately 68% of values fall within one standard deviation from the mean

Therefore, approximately 68% of the values fall between 9 and 11.

their product is 80 , that is

4x × 5x = 80

20x² = 80 ( divide both sides by 20 )

Hope has 6 nickels (x) and 10 quarters (x + 4).

How many of each coin Hope has if she has 4 more quarters than nickels and they have a combined value of 280 cents. To solve this problem, we can use algebraic equations.

Let's assume the number of nickels Hope has is x. Then, the number of quarters she has would be x + 4.

Now, we need to find the total value of the coins. Each nickel is worth 5 cents, so the total value of nickels is 5x cents. Similarly, each quarter is worth 25 cents, so the total value of quarters is 25(x + 4) cents. The combined value of the coins is 280 cents, so we can set up an equation:

5x + 25(x + 4) = 280

Simplify and solve for x:

5x + 25x + 100 = 280
30x = 180

         Total   [tex]t[/tex] (time) = [tex]t_1[/tex] ( time 1) + [tex]t_2[/tex] (time 2)

   Now, time 1 can be represented as

In order to have a potential value of $12,000 at a simple rate of interest of 8.0% after 6 years, the current value you must invest is therefore approximately $8,108.11.

A formula called Simple Interest (S.I.) is used to determine how much interest will be charged on a certain principal sum of money at a specific interest rate. For instance, if a person borrows Rs. 5000 for two years at a rate of 10 p.a., they will be compelled to pay S.I. on the whole amount borrowed during those two years.

For simple interest, use the formula:

A = P(1 + rt)

where r is the interest rate, t is the amount of time in years, A represents the future value, P is indeed the present value, and so on.

This formula can be changed to account for P:

P = A / (1 + rt)

By entering the specified values, we obtain:

P = 12,000 / (1 + 0.08 x 6)

P = 12,000 / 1.48

P = $8,108.11

The percentage of adults who planned to file their taxes electronically is approximately 63%.

A random telephone survey of 1,051 adults (aged 18 and older) was conducted by an online tax preparation and e-filing service. The survey results showed that 664 of those surveyed planned to file their taxes electronically.

Total number of adults surveyed = 1,051

Number of adults who planned to file their taxes electronically = 664

Percentage of adults who planned to file their taxes electronically is;

= (Number of adults who planned to file their taxes electronically / Total number of adults surveyed) x 100%

=(664/1051) x 100%

= 63.16 %

Therefore, the percentage of adults who planned to file their taxes electronically is approximately 63%.
