Answer:
x = -40
Step-by-step explanation:
Rewrite "(x - 4)/4" in a different way:
⇒ 8 + x/2 = (x - 4)/4 - 1
⇒ 8 + x/2 = x/4 - 4/4 - 1
Simplify the R.H.S:
⇒ 8 + x/2 = x/4 - 1 - 1
⇒ 8 + x/2 = x/4 - 2
Add 2 both sides and subtract x/2 both sides:
⇒ 8 + x/2 = x/4 - 2
⇒ 8 + 2 = x/4 - x/2
⇒ 10 = x/4 - 2x/4
Simplify the R.H.S:
⇒ 10 = x/4 - 2x/4
⇒ 10 = -x/4
Use cross multiplication:
⇒ 10 × 4 = -x
⇒ -(40) = x = -40

a bottle contains 24.5 oz of water. a leak in the bottle causes it to lose 0.3 oz of water every minute. how many minutes does it take for the bottle to lose 33% of the water?
Answer 54.7 Minutes
Step-by-step explanation:
33% × 24.5 =
(33 ÷ 100) × 24.5 =
(33 × 24.5) ÷ 100 =
808.5 ÷ 100 =
8.085 ≈
8.09;
so then 8.09 - 24.5 = 16.41
16.41 divided by 0.3 = 54.7
54.7 minutes it take for the bottle to lose 33% of the water.
What is Percentage?The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.
We have a bottle contains 24.5 oz of water.
A leak in the bottle causes it to lose 0.3 oz of water every minute.
So, 33% × 24.5
= (33 ÷ 100) × 24.5
= (33 × 24.5) ÷ 100
= 808.5 ÷ 100
= 8.085
= 8.09
So, the amount water loses
= 24.5 - 8.09
= 16.41 oz
Now, the amount of time for bottle to loose 33% of water
= 16.41 / 0.3
= 54.7 minutes

show that the (5,5),(5,0),and (0,0) are the vertices of an isosceles triangle.
An isosceles triangle has 2 sides that are equal.
I plotted these points. See attached screenshot.
The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.
The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.
These two sides make a right triangle and are equal length. This is an isosceles right triangle.

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.
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".

Find the best measure of variability for the data and determine which player was more consistent.
Player B is the most consistent, with an IQR of 3.5.
Player B is the most consistent, with a range of 10.
Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.
