Division is basically repeated subtraction.
For example, if you ask "what is 6 divided 2?", you're asking "how many times do I need to subtract 2 from 6 until I get to 0?"
Let's see it in action
6/2
6 - 2 - 2 - 2 = 0
As you can see, you subtract 2 from 6 three times, so 6 divided by 2 is 3.

DaMontre is at basketball practice, where he takes 30 shots a minute. He also took an extra 70 shots before practice. If DaMontre took 1,870 shots, how long did he practice for?
DaMontre practiced for 60 minutes after taking a total of 1,870 shots, with an initial 70 shots before practice and 30 shots per minute during practice.
Explanation:The question asks how long DaMontre practiced basketball if he took a total of 1,870 shots, with a pre-practice session of 70 shots, and during practice, he takes 30 shots a minute.
Step-by-step solution:
First, subtract the extra shots DaMontre took before practice from the total number of shots to find out how many shots were taken during practice. So, 1,870 - 70 = 1,800 shots during practice.
Next, to find out how long he practiced for, divide the number of shots taken during practice by the rate at which he takes shots per minute. Therefore, 1,800 shots divided by 30 shots/minute = 60 minutes.Thus, DaMontre practiced for 60 minutes, which is the answer to the question.
A designer wants to make a circular fountain inside a square of grass as shown at the right. What is a rule for the area A of the grass as a function if r
Answer:
[tex]A=4r^{2}-r^{2}\pi[/tex]
Step-by-step explanation:
1. To calculate the area of the grass you must substract the area of the square and the area of the circle.
2. The area of the square is:
[tex]A1=L^2[/tex]
Where [tex]L[/tex] is one side of the square.
3. You have that:
[tex]L=2r[/tex]
4. Therefore:
[tex]A1=(2r)^{2} =4r^{2}[/tex]
5. The area of the circle is:
[tex]A2=r^{2}\pi[/tex]
6. The are of the grass is:
[tex]A=4r^{2}-r^{2}\pi[/tex]
the water was pumped out of a backyard pond.what is the domain this graph?
Answer:
C) Real numbers from 0 to 8.
Step-by-step explanation:
We have been given a graph between depth (dependent variable) and time (independent variable). We need to figure out the domain of the given graph.
We know that domain is the set of values of independent variable for which the graph produces a finite value of dependent variable.
From the graph, we can see that for values of time between 0 and 8 minutes, the graph produces a finite value of depth. Therefore, domain of the given graph is all real numbers between 0 and 8 (inclusive).

Which expressions are equivalent to x+x+x + 2 ?
Choose 2 answers:
A
3x + 2
B
3 + 2x
C
3(x+2)
D
2(x+1)+x
E
5x
Answer:
A and D
Step-by-step explanation:
Only Answers A and D are equivalent to the given expression.
In A we see the variable 'x' show up three times, and so we write 3x + 2.
In D, after performing the indicated multiplication, we have 2x + 2 + x, which condenses to 3x + 2.
A mathematical expression is a finite arrangement of symbols and variables following a rule relating to the set of the finite variables.
From the given information:
x +x + x + 2= 3x + 2Also, we can have it has: 2(x+1) +x.
This is because if we simplify the above expression, we will arrive at 3x +2.
Let's solve:
The first thing we will want to do is to open the brackets
= 2(x+1) + x = 2x + 2 + xBy rearrangement of like terms, we have:
= 2x + x + 2= 3x +2Therefore, we can conclude that the mathematical expressions that are equivalent to x + x + x +2 are in Option A and D.

3.Patricia buys clothes that are on sale with a 30% discount. Let c represent the cost of the clothes. Write a linear expression for the cost of the clothes.
4.A family of four had dinner together at a restaurant. Write two expressions for calculating their total bill if they leave a 15% tip. Let c represent the cost of their meal before tipping.
5.Tommy has $40 in his pocket. He sees a pair of pants that cost $37 and wants to buy them. If there's 10% sales tax where Tommy lives, can he afford to buy the pants? Write a linear expression and use it to solve the problem.
6.Add the expressions x + 18 and 3x − 12.
7.Subtract 3x − 4 from 5x + 7.
8.Subtract −4x + 1 from x − 2.
1) Given m represent the total number of miles Hannah walked.
Let us assume Hannah walked x miles each day.
So total number of miles Hannah walked in 5 days is m=5x.
2)Given Jimmy brought 2 books per day and Peter brought 4 books per day.
If d is the number of days the book drive, total number of books they brought
=total number books brought by Jimmy+ total number of books brought by Peter
= 2d+4d = 6d
3) Given that c represent cost of the clothes.
Then 30% discount = 0.3c
Hence cost of the clothes = c-0.3c = 0.7c
4) Given c represent the cost of their meal before tipping.
And tip is 15% of the cost.
Hence tip = 0.15c
Hence total bill = c+0.15c=1.15c
5) Given that Tommy had 40$ in his pocket.
And pair of pants cost 37$ with 10% sales tax.
Hence cost of pants including sales tax = 37+37*0.1 = 40.1$ >40$
Hence Tommy cannot afford the pants with 40$ in his pocket.
For following problems, we should group the like terms together and then simplify.
6) (x+8)+(3x-12) = (x+3x)+8-12 = 4x-4
7) 5x+7-(3x-4) = 5x+7-3x+4 = (5x-3x)+7+4 = 2x+11
8) (x-2)-(-4x+1)=x-2+4x-1 = (x+4x)-2-1 = 5x-3

A student's cost for last semester at her community college was $2300. She spent $276 of that on books. What percent of last semester's college costs was spent on books?
Answer: There is 12% of last semester's college costs was spent on books.
Step-by-step explanation:
Since we have given that
Amount spent at her community college = $2300
Amount spent of that on books = $276
We need to find the percent of last semester's college costs was spent on books is given by
[tex]\dfrac{276}{2300}\times 100\\\\=\dfrac{27600}{23}\\\\=12\%[/tex]
Hence, there is 12% of last semester's college costs was spent on books.
The student spent 12% of last semester's college costs on books.
How to solve the percentageTo find the percentage of last semester's college costs that was spent on books, you can use the following formula:
Percentage = (Part / Whole) * 100
In this case:
The "Part" is the amount spent on books, which is $276.
The "Whole" is the total college cost for last semester, which is $2300.
Percentage = ($276 / $2300) * 100
Percentage = (0.12) * 100
Percentage = 12%
So, the student spent 12% of last semester's college costs on books.

Katarina wrote the standard form of a linear equation as 4x – 2/3 y = 8. Sofiya told her that the equation was not yet in standard form and gave her the right advice for how to fix it. What advice did Sofiya give to Katarina?
A. Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24.
B.Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.
C.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 8.
D.Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 4.
The standard form of a linear equation in general is given by:
[tex]ax+by=c[/tex]
Now we are given the equation :
[tex]4x-\frac{2}{3}y=8[/tex]
In order to convert this into standard equation, we have to eliminate the 3 in the second term on the left side of equation.
Here 3 is in division ,so we have to perform opposite operation of division that is multiplication.
So multiplying both sides by 3 , we have
[tex]12x-2y=24[/tex]
So that means option A.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. is the correct advice given by Sofiya.

hi, I am a sub for Glenridge and I need the answer to the question as soon as possible please here is the question Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weights 4 kg. The total weight of Carl's baggage is 35 kg.
Write an equation that illustrates the problem and can be used to determine the weight, w, of each of Carl's checked bags.
The equation to determine the weight of each of Carl's checked bags is 2w + 4 = 35. After solving, we find that each checked bag weighs 15.5 kg.
To solve the problem regarding Carl's baggage weight, we set up an equation. Carl has two checked bags of equal weight, let's call the weight of each bag w kilograms. He also has a backpack weighing 4 kg. According to the problem, the total weight of all his baggage is 35 kg. We can represent this situation with the following equation:
2w + 4 = 35
This equation adds the weight of the two checked bags (2w since there are two of them and they are equal in weight) and the 4 kg backpack to get the total weight of 35 kg. To find the weight of each checked bag, we can simply subtract the weight of the backpack from the total weight and then divide by two:
Subtract the weight of the backpack from the total weight: 35 - 4 = 31 kgDivide the remaining weight by two to find the weight of each checked bag: 31 / 2 = 15.5 kgTherefore, the weight of each of Carl's checked bags is 15.5 kg.
