Please help me. X/6 ≥ 7. I also need to know how this would be graphed thank you.
Answers
Answer: The inequality solves to x ≥ 42
The graph is shown below
==================================================
Explanation:
We have some unknown number x, and we're dividing by 6 to form the fraction x/6. That result is 7 or larger which means we write x/6 ≥ 7
To solve for x, we undo the division. We'll multiply both sides by 6. That's how we get to x ≥ 42
The graph will involve a number line. Plot a closed filled in circle at 42 on the number line. Shade to the right. This visually represents any number that is 42 or larger. The endpoint 42 itself is included in the solution set.
Side note: We would use an open circle if we didn't have the "or equal to" portion for the inequality sign.

Answers
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16
In a sale, the price of a bike is reduced by 40%
The sale price of the bike is £192
How much did the bike cost before the sale?
Answers
Answer:
£320
Step-by-step explanation:
So
The sale price is reduced 40% of the actual price
Actual price - 40% = £192
Actual price is the 100% price of the bike.
100% - 40% = £192
60% = £192
60% of the actual price of the bike is £192 but we need to find 100%.
To do that we need to find the price of 1%. To find this value we divide 60 into 192
\(192 \div 60 = 3.2\)
£ 3.2 is the 1% of the actual price.
To find the actual price (100%), you multiply 3.2 by 100
\(3.2 \times 100 = 320\)
So the actual price is £320
Hope this helps :)
Step-by-step explanation:
£192 = 60% of the original price (reduced by 40%).
1% of the original price = 60%/60 = 192/60 =
= 64/20 = 16/5 = 3.2
100% of the original price = 100×1% = 100×3.2 = £320
the bike cost £320 before the sale.

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values

Solve for x than find the perimeter
Answers
Answer:
136 in
Step-by-step explanation:
Assuming the figure is a square with equal sides, then
4x - 2 = 3x + 7 ( subtract 3x from both sides )
x - 2 = 7 ( add 2 to both sides )
x = 9
Thus side = 3x + 7 = 3(9) + 7 = 27 + 7 = 34
Thus
perimeter = 4 × 34 = 136 in
4x-2=3x+7
X-2=7

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answers
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

What equation models the line? I need help pretty fast.
Answers
Answer: y= 21x
Step-by-step explanation:
As you can see, the line is steadily increasing. To make an equation for the line, we need to use the formula y=mx+b.
Step 1: Find the slope, "m"
m is the slope of the line, calculated by finding 2 points on the line, and using the formula rise÷run.
To do this, find a point on the line. (Make sure it's an actual point, not one that is in between the lines). In this example I will use 0,0. Then, find the nearest (actual) point on the line. That will be 1,21.
Now, we will use rise/run.
To get from the 2 points I listed, we must rise, or go up, 21. Then, we must "run", or go left or right 1. In this case we go left.
Therefore, the "rise"= 21, and the "run"= 1. Now 21÷1= 21, so the slope is 21.
Step 2: Find the y-intercept, "b"
b is the y intercept of the line, whch is the first point on the y axis that the line is on. In this line, the y intercept is 0.
Step 3: Write the equation
Now that we know what "m" and "b" stand for, we can replace these letters with the numbers by plugging in.
y=mx+b
y= 21x+0
y= 21x
*Note that when the y intercept ("b") is 0, you don't write it in the equation, but if it were a number other than 0, you would.

Use your equation to determine the initial cost to the company, in dollars.
Initial cost to the company $ __
(The equation is c=5.25t-75.)
Answers
Answer: The initial cost to the company is $-75.
Step-by-step explanation:
To determine the initial cost to the company using the equation provided (c = 5.25t - 75), we need to understand what each variable represents:
c: The cost to the company in dollarst: The time (usually measured in hours, days, or weeks)Since the initial cost refers to the cost at the beginning (t = 0), we can plug t = 0 into the equation and solve for c:
c = 5.25(0) - 75
c = 0 - 75
c = -75
In this context, the initial cost to the company is $-75. It might seem unusual for the cost to be negative; however, this could be interpreted as the company having an initial credit or saving of $75 before any time has been spent on the project. Please note that the specific interpretation of this negative value depends on the context of the problem and the real-world situation being modeled by the equation.
