what integer divided by six, less eighteen, is negative twenty-two?

Answers

Simplifying what you said in your question would be x/6 - 18 = -22.
Therefore, you can solve the equation by adding 18 to both sides: x/6 = -4
Now, multiply each side by 6: x = -24. Check your answer by substituting -24 into the original equation and you will get -24 = -24

Please help I don’t understand.I need to know if it is a linear function and how to write it in standard form. :)

A linear function is one whose formula can be written in the form

Ax + By = C where A, B, C are real numbers and A, B are not both 0. (This is standard form, too.)

[tex]\frac{x+4}{2} = \frac{y-4}{3}[/tex]

"Cross multiply."

[tex]3(x+4) = 2(y-4) \\ 3x+12 = 2y-8[/tex]

Subtract 12.

[tex]3x=2y-20[/tex]

Subtract 2y.

[tex]3x-2y=-20[/tex]

This matches up with standard form with A = 3, B = -2, C = -20.

It's a linear function.

you live 3.67 miles from your grandparents and you are biking how do you solve this

Answers

To solve for revolutions, we will have to take the distance of the travel and divide that by the circumference of the wheel.

Distance of travel = 3.67 miles
Circumference of wheel = 82.6 inches

We have to convert the inches to miles. There are 63360 inches in one mile.

Circumference of wheel = 82.6 in * (1 mi/63360 in) = 0.0013 miles

Revolutions = Distance/Circumference = 63,538.46 revolutions

Determine the missing information in the paragraph proof.

Given: Line PQ contains points (w, v) and (x, z) and line P'Q' contains points (w + a, v + b) and (x + a, z + b). Lines PQ and P'Q' are parallel.

Prove: Parallel lines have the same slope.

Since slope is calculated using the formula , the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes.

Answers

Slope = change in y / change in x
Slope of PQ = (z - v) / (x - w)

Slope of P'Q' = (z + b - (v + b)) / ((x + a) - (w + a))
Slope of P'Q' = (z - v) / (x - w)

The slopes of both lines are equivalent to
(z - v) / (x - w)

If P(A) = 0.5, P(B) = 0.3, and P(A or B) = 0.6, find P(A and B)

Answers

P(A or B) = P(A) + P(B) - P(A and B), which means that the probability that A or B occurs is equal to the probability that A occurs plus the probability that B occurs minus the probability that both A and B occur.

So, you know P(A), P(B) and P(A or B) and you can solve for P A and B) =>

P(A and B) = P(A) + P(B) - P(A or B)

P(A and B) = 0.5 + 0.3 - 0.6 = 0.8 - 0.6 = 0.2

Answer: P(A and B) = 0.2

A line passes through the point (-6, 6) and (-6, 2). In two or more complete sentences, explain why it is not possible to write the equation of the given line in the traditional version of the point-slope form of a line

Answers

Try writing it in point-slope form and you will see why you have a problem.

slope m is equal to (y2-y1)/(x2-x1):

m = (y2-y1)/(x2-x1) = (2-6)/(-6 - -6) = -4/0

The denominator has a zero, so it is undefined.

Since the point-slope form requires "m" to be defined, you can't write the equation of the line using point-slope form.

The length of a rectangle is 6 1/2 inches and the width is 3 3/4 inches. What is the ratio, using whole numbers, of the length to the width?

Answers

The length is 13/2, while the width is 15/4, after combination. Ratio of length to width is then (13/2)/(15/4) = 26/15.

The ratio, using whole numbers of the length to the width is [tex]\frac{26}{15}[/tex]

Given the following data:

Length of a rectangle = [tex]6\frac{1}{2}[/tex] inches.Width of a rectangle = [tex]3\frac{3}{4}[/tex] inches.

To calculate the ratio, using whole numbers of the length to the width:

What is ratio?

Ratio can be defined as a mathematical expression that is used to denote the proportion of two (2) or more quantities with respect to one another.

How to calculate the ratio.

First of all, we would convert the mixed fraction to a proper fraction as follows:

For the length:

[tex]6\frac{1}{2}=\frac{13}{2}[/tex]

For the width:

[tex]3\frac{3}{4}=\frac{15}{4}[/tex]

Now, we can calculate the ratio, using whole numbers of the length to the width:

[tex]Ratio = \frac{length}{width} \\\\Ratio = \frac{\frac{13}{2} }{\frac{15}{4} } \\\\Ratio = \frac{13}{2} \times \frac{4}{15} \\\\Ratio =\frac{26}{15}[/tex]

Six people share 3/5 pound of peanuts equally. What fraction of a pound of peanuts does each person receive?

Answers

So first, I would convert 3/5 to 6/10, because it is equivalent and easier.

You can then just deduce that 1/10 would be 1/6 of 6/10, and that each person would therefore get 1/10 of a pound of peanuts.

You could also divide 3/5 by 6.

3/5 / 6 = 3/5 * 1/6

3/5 * 1/6 = 3/30

3/30 = 1/10

ratio 5 to 15 in a fraction lowest term

Answers

To do this, divide the numerator and denominator by the GCF. In this case, it's 5.

5:15
5 ÷ 5: 15÷5
1:3

Hope this helps!

To solve this ratio, we must first find the GCF, or the Greatest Common Factor, that is, the largest number that fits into both numbers. We can set up a table to compare the factors of each individual number, then identify common factors between the two numbers.

15 | 1 3 5 15
5 | 1 5

We see that the common factors include 1 and 5, however, 5 is the greatest common factor. Now we can simplify the ratio by dividing both numbers by 5.

5/5 = 1
15/5 = 3

Simplified Ratio: 1:3 (which is 1/3).

Express each ratio as a fraction in simplest form:

0.3 km to 500 m

Answers

Answer: 3/5

Step-by-step explanation:

The ratio shows how many times a number is contained in another. To express the ratio as a fraction in its lowest term, we convert 0.3km to metre.

1000 metre makes 1 kilometers. Therefore,

0.3km = 0.3 × 1000 = 300 metre

0.3 km to 500m= 300m to 500m

300m : 500m = 300/500

Reducing to its lowest term, 100 is a common factor.

300/500 = (100×3) / (100×5)

= 3/5.
