Hey! Your question was incomplete because I have double-checked my work, and even checked reliable sources to see if I missed something in my work, but I keep getting –238. I did play around with the question by switching the negative symbol around in the equation to see if I would get a balanced answer. I say this because when you solve the question you posted, the answer I got was w = –238, but when I went back to check my work by plugging that number in as the value of w, I got –238 ≠ 238 (or something like that. The number is the same, but the signs are not). If the signs and numbers don't both equal each other something is wrong with the problem. I believe I figured out where your question went wrong. Instead of the question being 34 = –w/7, I believe that the correct question should have been –34 = w/7. What I think happened was that when you typed your question, you swapped the negative on the 34 with the variable of w. If I am incorrect, and you typed your question correctly, I am sorry in advance because my work wasn’t matching what I got for w. But for now, I will solve what I think the question should have said. Again, sorry in advance. Solve for w in the following equation: –34 = w/7.
Write the equation:
–34 = w/7
Multiply both sides by 7:
7 × –34 = w/7 × 7
Multiply:
–238 = 1w
Divide:
–238/1 = 1w/1
–238 = w or w = –238
Check your work by plugging –238 back into the equation as w:
–34 = w/7
–34 = –238/7
Multiply both sides by 7:
–34 × 7 = –238/7 × 7
–238 = –238 ✔
Thus, w = –238
Hope that helps! Have an amazing rest of your day!! :)
what is the value of n?
Answer: Sorry for the late answer, I was already answering it by the time someone else answered
Step-by-step explanation:
Since two angles on a straight line add up to 180, I used the angles given to find the adjacent angles to it by subtracting those angles from 180. Then, since the angles of a triangle add up to 180, I used the angles I just solved for to find the angle that is adjacent to n. I did the same thing I did to the first two angles by subtracting it from 180 to find n, which was 69 degrees

Solve 7x − 2(x + 1) = 6x + 14
A. x = −12
B. x = 12
C. x = −16
D. x = 16
I don't know what to do here.
Answer: C, x = -16
Step-by-step explanation:
1. Distribute
7x-2(x+1)=6x+14
7x-2x-2=6x+14
2. Combine like terms
7x-2x-2=6x+14
5x-2=6x+14
3. Add 2 to both sides
5x-2+2=6x+14+2
4. Simplify
Add the numbers
5x=6x+16
5. Subtract 6x from both sides
5x-6x=6x+16-6x
6. Simplify
Combine like terms
-x=16
7. Divide both sides by the same factor
-x/-1=16/-1
8. Simplify
Cancel terms that are in both the numerator and denominator

|-4/3x-5|>19
Solve with work please. ;)
The inequality expression given as |-4/3x - 5| > 19 has a solution of 10.5 < x < -18
How to solve the inequality?From the question, the inequality is given as
|-4/3x-5|>19
Rewrite properly as
|-4/3x - 5| > 19
Remove the absolute bracket
So, we have the following representation
-19 > -4/3x - 5 > 19
Add 5 to all sides of the inequality
So, we have
-14 > -4/3x > 24
Multiply through by -3/4
So, we have
10.5 < x < -18
Hence, the solution to the expression is 10.5 < x < -18

What is average in ?
In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.Identify number to average that is 19,17,14,13 over four day period.

justina needs to dilate traiangle ABC using a scale factor of 1.5
Using the rule for a dilation, it is found that:
1. The table with the coordinates is given by the first image.
2. The graph of the dilated triangle is given by the second image.
3. The rule is: (x,y) -> (1.5x, 1.5y).
What is the effect of a dilation of a figure?When a figure is dilated by an scale factor of a, each vertex of the figure is multiplied by the scale factor of a, hence the rule is given by the following vector:
(x,y) -> (ax, ay).
The coordinates of the vertices of the pre-image are given as follows:
A(-2, -2), B(2,2), C(4, -2).
The dilation has a scale factor of 1.5, hence the rule for the calculation of each vertex of the image, considering the pre-image, is given as follows:
(x,y) -> (1.5x, 1.5y).
Then the vertices of the image will be given as follows:
A'(-3, -3), B'(3,3), C'(6, -3).
Each coordinate of A, B and C was simply multiplied by 1/2, and the triangle with these vertices is given by the second image at the end of the answer.

An airplane travels 130,000 feet horizontally drring take-off, reaching a height of 35,000 feet. the airplane travels at a constant rate.what is the plane's launch angel? round your answer to the neatest degree.
The launching angle of the plane which has reached a height of 35000 ft is 15°
Let the distance travelled by the airplane horizontally be AB
The height reached by the airplane be BC
Thus AB = 130000 ft
BC = 35000 ft
The launching angle of the airplane can be found using the formula
tanθ = opposite / adjacent
(or)
tanθ = BC / AB
Let us substitute the known values in the above equation, we get
tanθ = 35000/130000
tanθ = 0.2692
θ = tan⁻¹ (0.2692)
θ = 15.067°
θ ≅ 15°
Therefore , the launching angle of the airplane is 15°

in july, abby's gym membership will increase by 18% a month. if she is currently paying $32 a month how much will she pay in july?
The exponential function that shows the amount of money paid for membership x months after the beginning of the year is given by y = 32(1.18)ˣ.
What are the types of exponential function?There are two possibilities for the exponential function: it can be increasing or decreasing. Being increasing means that as the value of x increases, the value of f(x) also increases; being decreasing means that as the value of x decreases, the value of f(x) also decreases.

Hooke's Law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 180 newtons stretches a spring 5 cm, how much will a force of 270 newtons stretch the same spring?
7.5cm distance a spring when a force of 270 newtons stretch the same spring.
What is force?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given Data
A force of 180 newtons stretches a spring 5 cm
If we consider F to be the force and x to be the extension, then:
F = kx
F = 180
x = 5
Equating
180 = 5k
k = 36
F = 36x

What is an equation of the line that passes through the point (6,1)(6,1) and is parallel to the line x+3y=15
Answer:
Step-by-step explanation:
Let's write everything in slope-intercept format of y=mx+b, where m is the slope and b is the y-intercept.
x+3y=15
3y= -x + 15
y = (-1/3)x + 5
Parallel lines will have the sam slope, in this case -(1/3), So the new line will be:
y = (-1/3)x + b
We need to fijnd a value of b that will force the ine through point (6,1). Enter (6,1) in the equation and solve for b:
y = (-1/3)x + b

What are the angles of triangle?The straight angle is equal to the total of the angles of a triangle. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle. For a very long period, it was unknown if there were any alternative geometries for which the total is different.
The triangle has three sides and is a two-dimensional figure having the sum of the angles of 180 degrees.
In the given image the three angles are 2t, t + 8, and t - 12. The value of t will be calculated as:-
2t + t + 8 + t - 12 = 180
4t - 4 = 180

By using the concept of uniform rectilinear motion, the distance surplus of the average race car is equal to 3 / 4 miles. (Right choice: A)
How many more distance does the average race car travels than the average consumer car?
In accordance with the statement, both the average consumer car and the average race car travel at constant speed (v), in miles per hour. The distance traveled by the vehicle (s), in miles, is equal to the product of the speed and time (t), in hours. The distance surplus (s'), in miles, done by the average race car is determined by the following expression:
s' = (v' - v) · t
Where:
v' - Speed of the average race car, in miles per hour.v - Speed of the average consumer car, in miles per hour.t - Time, in hours.Please notice that a hour equal 3600 seconds. If we know that v' = 210 mi / h, v = 120 mi / h and t = 30 / 3600 h, then the distance surplus of the average race car is:
s' = (210 - 120) · (30 / 3600)
s' = 3 / 4 mi
The distance surplus of the average race car is equal to 3 / 4 miles.
