Could someone tell me the step to step guide on how to do any subject formulas question in Maths and could someone help me do the subject formulas questions in the photo☺
Answers
Our first step would be to separate the coefficient of the value from everything else (the coefficient is what the value is multiplied by). Therefore, in 2x-4=y, we have to add 4 to both sides to separate 2x, resulting in 2x=4+y. Next, we have to divide by the coefficient to separate x (in this case, 2), resulting in x=(4+y)/2
For the next one, we repeat the process - add 6 to both sides since it's subtracted by 6 (conversely, if we were to be adding 6 to 8b originally we would subtract 6 from both sides) to get 8b=6+a. Next, we divide both sides by 8 to get b=(6+a)/8.
For the third one, we add 1 to both sides to get 4d=c+1 and then divide both sides by 4 to get d=(c+1)/4

plot the fraction 7/12 on the number line . is 7/12 closer to 0, 1/2 or 1 ?
Answers
To plot 7/12 on the number line, divide the line into equal parts and determine where 7/12 falls. 7/12 is closer to 1 than to 1/2 or 0.
Explanation:Plotting a fraction, such as 7/12, on a number line involves breaking down the interval into equal parts and determining the position of the fraction within that range. In this case, the fraction 7/12 is being considered.
To understand where 7/12 falls on the number line, it's essential to consider both the numerator (7) and the denominator (12). When comparing fractions, having a larger denominator signifies smaller parts, while a larger numerator indicates more parts taken. In this context, the denominator 12 is greater than 2, suggesting that 1/2 is smaller than 7/12. Additionally, since the numerator 7 is smaller than 12, we can conclude that 1 is smaller than 7/12.
As a result of these comparisons, it becomes apparent that 7/12 is closer to 1 on the number line than it is to 1/2 or 0. This intuitive understanding of fraction placement on a number line helps in visualizing the relative sizes and positions of fractions, contributing to a deeper grasp of mathematical concepts and comparisons.

Which of the following are true statements about David Hilbert
Answers
Final answer:
The student question doesn't correctly pertain to David Hilbert; thus, an answer specific to him is not provided. Instead, a brief description of Hilbert’s contributions to mathematics is outlined, showing a potential misunderstanding or typo in the original question.
Explanation:
The question does not directly relate to David Hilbert, hence answering the question as posed is not possible. David Hilbert was a renowned German mathematician known for his contributions to fields such as invariant theory, the calculus of variations, commutative algebra, and algebraic number theory. His work also had a profound influence on the foundations of mathematics, especially through the establishment of formalism as a philosophy of mathematics, and his famous list of 23 unsolved problems presented in 1900. Notably, Hilbert's name is often associated with the Hilbert's Program, which aimed to provide a complete and consistent set of axioms for all of mathematics, and the Hilbert space, which is a concept in functional analysis that provides a general framework for the mathematical formalism of quantum mechanics. Unfortunately, the information provided in the student question references several other philosophers and mathematicians, such as Harman, Dharmakīrti, Leibniz, Pierce, Hume, and Heisenberg, rather than focusing on Hilbert's life and work.
Two youth groups participated in a three-week recycling project. Group A collected 15.49 pounds during week 1, 20.82 lb during week 2, and 22.91 pounds during week 3. Group B collected three times as much as Group A. Enter the total amount that Group B collected.

The total amount that Group B collected 177.66 pounds.
Given that, group A collected 15.49 pounds during week 1, 20.82 lb during week 2, and 22.91 pounds during week 3.
How to add the decimals?To add two decimal numbers, first check if they have the same number of digits to the right of the decimal point. If they don't, add zeros to the right of one of the numbers until they do. Then, write one number on top of the other, lining up the decimal points vertically.
Now, add the quantity of recycling material collected during three week.
That is, 15.49 + 20.82 + 22.91 = 59.22
Given that, group B collected three times as much as Group A.
So, 3 × 59.22 = 177.66
Therefore, the total amount that Group B collected 177.66 pounds.

in geotown, there are 210 own a tablet. This is at least 4/5 of all teenagers that live in geotown. What is the maximum number of teenagers who live geo town
Answers
Then you divide 210 by the numerator to get 1/5 people:
210 / 4 = 52.5
Then you can multiply the 1/5 people (52.5) by 5 to get 5/5:
52.5 * 5 = 262.5 (rounded to 262)
Thus the maximum amount of teenagers in Geotown is 262.
Hope this helps! :)
The maximum number of teenagers who live in Geotown can be found by solving an equation using the given information that 210 teenagers own a tablet, which is at least 4/5 of all teenagers in Geotown.
Explanation:We are given that 210 teenagers own a tablet, and this number is at least 4/5 of all teenagers in Geotown. Let's represent the total number of teenagers in Geotown as 'x'. According to the given information, 4/5 of x is equal to 210. We can set up the equation (4/5)x = 210 and solve for x.
To solve for x, we can multiply both sides of the equation by the reciprocal of 4/5, which is 5/4. This gives us x = (5/4) × 210 = 262.5. However, since the number of teenagers must be a whole number, we round down to the nearest whole number and conclude that the maximum number of teenagers who live in Geotown is 262.

Answers
Answer:
The total repair cost for each store is the cost of repairs added to the sales tax. The amount of money saved will be the difference between the two total costs.
Step-by-step explanation:
Endogeneity answers
The new total cost Sarah has to pay, including the 15% gratuity is $1690.07. This is calculated by adding her repair cost, shipping fee, and gratuity together.
Explanation:The total cost that Sarah has to pay can be calculated by adding up the cost of computer repair, the cost of shipping, and the gratuity she wants to include. The cost of shipping is 2 percent of the total cost of computer repair, so it would be $1,444.50 * 0.02 = $28.89. The gratuity Sarah wants to pay is 15 percent of the total cost of the computer repair (excluding the cost of shipping) which is $1,444.50 * 0.15 = $216.68.
Adding all these together: $1444.50 (Cost of Repair) + $28.89 (Shipping) + $216.68 (Gratuity) gives us a total cost of $1690.07. This will be the new total cost Sarah has to pay.

The table shows the outputs, y, for different inputs, x:
Input (x) 6 12 15 25
Output (y)14 15 15 16
Part A: Do the data in this table represent a function? Justify your answer.
Part B: Compare the data in the table with the relation f(x) = 7x − 15. Which relation has a greater value when x = 6?
Part C: Using the relation in Part B, what is the value of x if f(x) = 6?
Answers
----------------------------------------------
Part B: Plug x = 6 into the f(x) function given to get
f(x) = 7x-15
f(6) = 7*6-15
f(6) = 42-15
f(6) = 27
Now compare this with the table. According to the table, when x = 6, the value of y is 14. So the f(x) value is larger than the table value when x = 6
----------------------------------------------
Part C:
Replace f(x) with 6 and solve for x
f(x) = 7x-15
6 = 7x-15
6+15 = 7x-15+15
21 = 7x
7x = 21
7x/7 = 21/7
x = 3
So the final answer, for part C, is x = 3

[tex](x^m \cdot x^2)^3=({x^{2m}})^3=x^{2m \cdot3}=x^{6m}[/tex]
by first applying property i) then property ii)
also, [tex]({k}^3)^5=k^{15}[/tex], by property ii)
So we have:
[tex]({x^m \cdot x^2})^3 \cdot({k}^3)^5=x^{21} \cdot k^{15}\\\\x^{6m}\cdot k^{15}=x^{21} \cdot k^{15}[/tex],

TO get the number of bags, we simply get the quotient, that is:
(12 / 15 pounds) / (1 / 3 pounds) = 2.4 bags
Since bags cannot be decimal, so it can only fill 2 bags. The left over is 0.4 or:
0.4 * (1/3) = (2/5) * (1/3) = 2/15 pounds
Answer:
2 bags filled, left over is 2/15 pounds of granola
