when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.
Does the given linear equation has solutions?
Here we have the following linear equation:
15 + 3*(2x - 9) = 44
And we want to see if this has a solution, it means that there is a value of x such that the equation becomes true. Let's see that.
To do it, we need to isolate the variable, x, in one of the sides of the equation.
Expanding the product we get:
15 + 3*2x - 3*9 = 44
Moving the terms without x to the right side:
15 + 6x - 27 = 44
6x = 44 + 27 - 15 = 56
Now we can divide both sides by 6 so we get:
x = 56/6 = 9.33
So, when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.

What do you mean by the unitary method?The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
As a result, multiplying by 2, the man travels 3.5 miles in one hour.
The distance the man walks in 7 hours, multiplied by 7, comes out to be 24.5 miles. Alternatively, you might divide the man's distance traveled by 7, or X, to get 7 (x/7). It equals the time needed to travel X miles, which is 2 hours (7/2), divided by the time needed to go X miles, which is 7 hours. X, therefore, equals 24.5 miles.

The perimeter of the polygon with the vertices. U(-2,4), V(3,4), W(3,-4). Round your answer to the nearest hundredth.
The Perimeter of the polygon = 22.43 units.
How to Determine the Perimeter of a Polygon?Given the vertices of the polygon as:
U(-2,4)V(3,4)W(3,-4)The perimeter of the polygon is the sum of all its sides, UV + VW + UW.
Apply the distance formula, d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex] to find the length of each of the three sides of the polygon as shown below:
UV = √[(3−(−2))² + (4−4)²]
UV = √[(5)² + (0)²]
UV = √25
UV = 5 units
VW = √[(3−3)² + (4−(−4))²]
VW = √64 = 8 units
UW = √[(−2−3)² + (4−(−4))²]
UW = √89 = 9.43 units
Perimeter of the polygon = 5 + 8 + 9.43
Perimeter of the polygon = 22.43 units

Mr. Zuro finds the mean height of all 16 students in his statistics class to be 67.0 inches. Just as Mr. Zuro finishes explaining how to get the mean, Danielle walks in late. Danielle is 63.6 inches tall. What is the mean height of the 17 students in the class?
Answer:
66.8 inches
Step-by-step explanation:
The mean height of 16 students is 67.0"
Total height of 16 students = 67 x 16 = 1,072"
When Danielle walks into the class an additional height of 63.6" is added to the total and the new total becomes 1072 + 63.6 = 1135.6"
Since there are now 17 students, mean = 1135.6/17 = 66.8"

Pls answer asap 100 points
Step-by-step explanation:
To tell if something is longer than another object is to find the difference between the two objects.
If the difference is < 0, then the object is shorter
If the difference is = 0, then the objects are equal in length
If the difference is > 0, then the object is longer
[tex]6.5 * 10^{-9}[/tex] - [tex]4.75 * 10^{-9}[/tex] = [tex]1.75*10^{-9}[/tex]
The difference is > 0, so the wavelength is longer.

What if the large ferris wheel makes one revolution in 10 seconds and the small wheel makes one revolution in 7 seconds, how many revolutions will each ferris wheel need to complete before you and your sister are at the bottom at the same time?
For you and your sister to reach bottom at the same time, the large Ferris wheel has to take 7 revolutions and the small Ferris wheel has to take 10 revolutions.
Time taken by the large Ferris wheel to complete 1 revolution = 10 seconds.
Time taken by the small Ferris wheel to complete 1 revolution = 7 seconds.
For them to reach bottom at the same time, we need to calculate their least common multiple.
LCM of 10 and 7 will be :
LCM = 10 × 7 = 70 seconds.
Revolutions taken by large Ferris wheel will be = 70 / 10 = 7 revolutions.
Revolutions taken by small Ferris wheel will be 70 / 7 = 10 revolutions.
Therefore, for you and your sister to reach bottom at the same time, the large Ferris wheel has to take 7 revolutions and the small Ferris wheel has to take 10 revolutions.

5. Charnita Jones earns $304.80 per week as a sales assistant. Next week she will be
promoted to assistant manager. She will then earn $332.50 per week. She is single
and claims 1 allowance. How much more will she pay in federal income tax?
Charnita Jones will have to pay $5 more in federal income tax.
According to the question we have been given that Charnita Jones
As sales assistant she earned = $304.80
After promotion as assistant manager she will earn = $332.50
Number of allowance she claims = 1
We need to find how much more she will pay in federal income tax.
For that we will first calculate how much she paid when her earning was $304.80. For this we will use the table for single persons-weekly payroll period. In that table, first we will choose the row of wages from the column number 1. We look to that row where $304.80 will lie that is the row will be $300-$310. then we will look for allowance that is 1. Thus the tax she will pay will be in column of allowance 1 and in the row of $300-$310 is $22.
In similar way we will find out the tax she will pay when she earn $332.50 which is $27.
Difference = $27 - $22 = $5
Hence she will have to pay $5 more in federal income tax.

You average 55 miles per hour while driving to a relative's house. On the return trip, you average 50 miles per hour because of bad weather. The total driving time is 5 hours and 15 minutes. How long does each trip take?
We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.
How long does each trip take?
Remember the relation:
Distance = Speed*Time.
Here the total distance of the trip is 55mi + 50mi = 105mi
And the total time is 5 hours and 15 minutes, remember that:
60 min = 1 hour
Then; 15 min = 0.25 hours.
So the total time is 5.25 hours, with that we conclude that the average speed is:
S = 105mi/5.25 h = 20 mi/h
The first trip is 55 miles long, then the time in which it is travelled is:
T = (55 mi)/(20 mi/h) = 2.75 hours
The second trip is 50 miles long, then:
T' = (50mi)/(20 mi/h) = 2.5 hours.
We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

What is the average rate of change of the function f(x)=x2–5x+14 on the interval from x=3 to x=5?
Answer:
3
Step-by-step explanation:
To find the average rate of change from two points: [a, b] we generally use the slope equation, which can be represented as: [tex]\frac{f(a)-f(b)}{a-b}[/tex]
So here let's first calculate f(3) and f(5)
[tex]f(3)=(3)^2-5(3)+14\\f(3)=8\\\\f(5)=(5)^2-5(5)+14\\f(5)=14[/tex]
Now let's plug these values into the equation: [tex]\frac{f(5)-f(3)}{5-3}[/tex]
To get the equation: [tex]\Longrightarrow \frac{14-8}{5-3}=\frac{6}{2}=3[/tex]
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line = rise/run = 2/3.
How to Determine the Slope of a Line?To determine the slope of a line, we can find the ratio of the rise of the line to that of its run.
Therefore, slope (m) of a line = rise/run.
Rise = vertical distance across the line
Run = horizontal distance across the line
In the graph given, we have:
Rise is the blue line = 6 units
Run is the red line = 9 units
Slope of the line (m) = 6 units/9 units
Slope of the line (m) = 2/3
Therefore, In simplest form, the slope of the line = rise/run = 2/3.
