To determine the monthly charge for a cell phone plan with a flat fee and a fee per 50 MB of data used, we use a linear equation. For example, with a flat fee of $20 and a per 50MB data charge of $2, the equation for the monthly cost (C) would be C = 20 + 2D, where D reflects the number of 50MB increments used.
Explanation:For the scenario you're describing, you would typically use a linear equation where one part is constant (the flat fee), and the other changes based on the amount of data (measured in 50 MB sets) the customer uses. Let's consider a scenario where you're charging a flat fee of $20 and a fee of $2 for every 50 MB of data used during the month. Then, the equation for the cost, C, each month would be:
C = 20 + 2D
In this equation, D reflects the number of 50MB data increments used by the customer. So, if a customer uses 150 MB of data in a month, D would equal 3, as 150 MB is three sets of 50 MB. The total cost for this customer would be:
C = 20 + 2(3)
C = $26
The set $20 is the flat fee and the varying part, 2D, reflects the data charge. Hence, the total bill for a customer any given month would depend on their data usage.

The product of 9 and a number is 12 less than three times that number.
What is the number?
_____
I can only Write 4 Numbers so it need the Whole Number Answer
The number is 9.
To find the number, we can set up an equation based on the given information. Let's denote the number as [tex]\( x \)[/tex]. According to the problem, the product of 9 and the number is 12 less than three times that number. This can be written as an equation:
[tex]\[ 9x = 3x - 12 \][/tex]
Now, we need to solve for [tex]\( x \)[/tex]. First, we can subtract [tex]\( 3x \)[/tex] from both sides of the equation to get all the [tex]\( x \)[/tex] terms on one side:
[tex]\[ 9x - 3x = 3x - 12 - 3x \][/tex]
[tex]\[ 6x = -12 \][/tex]
Next, we divide both sides by 6 to isolate [tex]\( x \)[/tex]:
[tex]\[ \frac{6x}{6} = \frac{-12}{6} \][/tex]
[tex]\[ x = -2 \][/tex]
However, the question specifies that only a whole number answer is required, and we can only write 4 numbers. Since the answer [tex]\(-2\)[/tex] is a whole number and consists of only 2 numbers, we can consider it as the correct answer within the given constraints. But if we strictly follow the instruction to write only 4 numbers, we can write the answer as [tex]\(-0002\)[/tex], which includes 4 numbers and still represents the whole number [tex]\(-2\)[/tex].

3. Iowa = [tex]\frac{2990000}{56276}[/tex] = 53.13 people per square mile.
4. New Jersey = [tex]\frac{8690000}{8722}[/tex] = 1007.9 people per square mile.
5. Wyoming = [tex]\frac{522000}{97818}[/tex] = 5.3 people per square mile.

Cooper needs a total of 70.4 mL of milk and butter for his recipe.
The recipe calls for 30.6 mL of butter.
So the rest of it should be milk.
How much? Total - Butter = Milk

Adriano runs a website that helps writers write better stories. Every month, Adriano receives a subscription fee of $5 from each of the subscribers to his website. The website had 200 subscribers last month. This month 40 new members joined the website and 10 members cancelled their subscription
After accounting for new subscriptions and cancellations, the website has 230 current subscribers, resulting in a total monthly revenue of $1150 from subscriptions.
Explanation:The question involves a straightforward mathematical problem concerning subscription counts and fee calculations for a website, which is typically a topic covered under basic arithmetic or algebra in middle school mathematics. To answer the student's query, we need to calculate the new number of subscribers after accounting for the 40 new members who joined and the 10 members who cancelled their subscription. The initial number of subscribers was 200. With 40 new subscribers joining and 10 unsubscribing, the new total number of subscribers is given by:
Initial subscribers + New subscribers - Unsubscribed members
200 + 40 - 10 = 230
Next, we calculate the total subscription fee revenue for the current month by multiplying the number of subscribers by the monthly subscription fee which is $5:
Total revenue = Number of subscribers × Subscription fee per subscriber
Total revenue = 230 × $5 = $1150
Therefore, the revenue from subscriptions for this month is $1150.

the coordinates of d.e.f are d (4,3),e (7,3)and f (6,8). if you translate d.e.f 4 unite left and 3 unite up what are the coordinates of f?
To find the new coordinates of point F after translating it 4 units left and 3 units up, we adjust its x-coordinate by subtracting 4 and its y-coordinate by adding 3, resulting in the new coordinates (2, 11).
Explanation:The student is asking about a translation of a geometric figure in the coordinate plane. The coordinates of point F are initially (6,8). A translation of 4 units left and 3 units up would change these coordinates. To translate 4 units left, we subtract 4 from the x-coordinate, and to translate 3 units up, we add 3 to the y-coordinate.
Therefore, the new coordinates of point F after the translation would be:
F' = (6 - 4, 8 + 3) = (2, 11).

The cost of peanuts varies directly with the number of pounds. if 3 pounds of peanuts cost $6.30, what is the cost of 4.5 pounds
The cost of 4.5 pounds of peanut is $9.45.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Cost of 3 pounds peanuts = $6.30
So, Cost of 1 pounds = 6.30/ 3
= $2.10
Then, Cost of 4.5 pounds
= 4.5 x 2.10
= $9.45
Hence, cost of 4.5 pounds of peanut is $9.45.

Lizzy has 6.5 hours to tutor 4 students and spend 1.5 hours in a lab. She plans to tutor each student the same amount of time. The inequality 6.5 - 4t (greater than or equal to)5 can be used to find t, the amount of time in hours Lizzy could spend with each student. Solve the inequality. Can Lizzy tutor each student for 1.5 hours? Explain.
Lizzy can tutor each student for at least 1.25 hours, so she cannot tutor them for 1.5 hours as it exceeds the maximum time available per student according to the inequality 6.5 - 4t \<= 1.5.
Lizzy has a total of 6.5 hours to distribute between four students and her 1.5 hours in a lab. To figure out the maximum time she can spend tutoring each student (t), we use the inequality 6.5 - 4t \<= 1.5. Solving this inequality:
First, add 4t to both sides: 6.5 \<= 1.5 + 4t.Then, subtract 1.5 from both sides: 6.5 - 1.5 \<= 4t, or 5 \<= 4t.Finally, divide both sides by 4: 5/4 \<= t, which simplifies to 1.25 \<= t.This means that Lizzy can spend at least 1.25 hours with each student. Therefore, she cannot tutor each student for 1.5 hours because 1.5 is greater than 1.25. The critical point to note here is that the inequality dictates the maximum amount of time Lizzy has per student, not the minimum.

BTW u spelled Algebraic wrong!!!
Final answer:
The algebraic equation based on the given information is 50 / (x + 5) = 10, which can be solved by first multiplying both sides by (x + 5).
Explanation:
The student's question can be converted into an algebraic equation. If ‘x’ represents the unknown number, the phrase “five more than a number” translates to “(x + 5).” The “quotient of fifty and (x + 5)” implies division, so we express this as “50 / (x + 5).” According to the information provided, this quotient is equal to ten. Hence, the algebraic equation reflecting the student's question is:
50 / (x + 5) = 10
To find the value of ‘x’ that satisfies this equation, you would solve it by multiplying both sides by (x + 5) to get rid of the denominator, which gives us:
50 = 10(x + 5)
This can then be simplified to find the value of ‘x’.

The Clark family must pay $2,820 in property tax on their home this year. The house payment $752 per month. What is their payment each month with the tax? Assume that the tax is paid in equal monthly installments.
Answer:
Step-by-step explanation:
First, you must find how much they pay in one month, not including tax. Since there are 12 months in a year, you have to do 2820/12 to get 235.
Next, you must add the quotient to 752, which they pay in one month. 235+752=987. They pay $987 in one month.
