Which expression is equivalent to −1/4x+1/2?
A. −1/4(−x+1/2)
B. 1/4(−x+1/2)
C. 1/4(−x+2)
D. −1/4(x+2)
Answer: D. −1/4(x+2)
Step-by-step explanation: The expression -1/4x + 1/2 can be simplified by factoring out 1/4, which gives -1/4(x - 2).
Therefore, the expression that is equivalent to -1/4x + 1/2 is D. -1/4(x+2).
Given the equation 6x + 18 = 72:
Part A: Write a short word problem about a purchase made to illustrate the equation. (6 points)
Part B: Solve the equation showing all work. (4 points)
Answer:
Part A: You are buying candy bars online. They cost $6 each and there is an $18 shipping fee. You have $72 to spend. How many candy bars can you get?
Part B: x=9
Step-by-step explanation:
6x + 18= 72
You want to get x alone:
Subtract 18 from both sides
Rewrite:
6x= 72-18
Now, subtract 72-18
Rewrite:
6x= 54
Divide 6 from both sides
So, that would be 54/6
Answer: x=9

What is the interquartile range of this data set?
Answer:
13
Step-by-step explanation:
To find the interquartile range you would first have to find the median. If you list the number in least to greatest order you will find that the median is 30.5. After you find the median you will spilt the data set up. So on one side it will be 20, 25, 30 and 30, the other side you be 31, 40, 41, and 49. Next, you would find the median of the first set that I listed which is 27.5. You would do the same for the second set and find the median which is 40.5. You would then subtract the first sets median from the second sets median which is 40.5-27.5 and that is 13.

Tell whether lines m and n must be parallel from the given
Information. If they are, state your reasoning.
Answer:
The first one isn't the second one is.
Step-by-step explanation:
In the first one, they have to be equal because they're corresponding angles so m and n are parallel.
In the second one, m<2 and m<3 would be supplementary and add up to 180 degrees if the lines were parallel and since they don't add up to 180, the lines are not parallel.

Step-by-step explanation:
February:
4,100 water bottles.
March:
(4,100 + 7/100 x 4,100) water bottles
(4,100 + 287) water bottles.
4,387 water bottles.
April:
(500 + 4,387) water bottles.
4,887 water bottles.
= (4,887 - 4,100) / 4,887 x 100
= 787/4,887 x 100
= 16%
The percentage change is 16%.

Ramiro did a survey of the number of pets owned by his classmates, with the following result
What was the mean Deviation of the number of pets?
A-1.02
B-1.053
C-1.087
D-1.12
The mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12
To find the mean deviation of the number of pets, the following steps would be taken:
Find the mean, which is sum of each frequency and score (fx) divided by the total number of pets. \(\mathbf{(\frac{\sum fx}{n} )}\)Subtract the mean from each score, \(\mathbf{( x - \bar x)}\)Sum the deviations together and divide by total number of pets.The formula for the mean deviation is given as: \(\mathbf{\frac{\sum f* |x - \bar x|}{n} }\)Mean deviation as solved in the table attached in the image below would be:
\(\mathbf{\frac{33.6}{30} = 1.12}\)
Therefore, the mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12

Step-by-step explanation:
10)We have to calculate the average speed if we know the distance and time that Johnatan can jog. The distance
distance=3 2/5 miles = 3.4 miles.
Time=7/8 hour = 0.875 h
Then we will use the formula for the average speed ( velocity )
velocity=distance/time. v = 3.4 m / 0.875 h = 3.866 mph
so therefore The average speed is 3.866 mph.
11) divide 120 / 7/4 (remember 120 = 120/1)
Which means you have to cross multiply (an important part on fraction division, that is, your division would be 120x4 / 1x7).
Then 120x4= 480
And 1x7 = 7
Then you get 480/7, which is the same as 68 4/7 mph

Translate the following phrase to a mathematical expression.
a number times fifteen
(A) 15 n
(B) 15 + n
(D) 15 ÷ n
(C) n15
Answer:
I think C
Step-by-step explanation:
A number times fifteen would be n • 15 or just n15.
The reason it is not 15n is because it asks a "number" which in this case is represented by the letter n. That letter is now multiplied (times) by 15. So therefore the number "n" times 15 is n15.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Answer:
x = -5
Step-by-step explanation:
In both questions you want to get the x alone.
1.
-3x + (-6) = 9
First you want to add 6 to both sides so you'll be left with:
-3x = 15
Next, you want to divide both sides by -3 and you'll get:
x = -5
2.
-4x + (-12) = 8
You want to do the same thing as the first one so you'll add 12 to both sides:
-4x = 20
Then, you will divide both sides by -4 and get:
x = -5
