D = c-s/n
Dn = n(c-s/n)
Dn = c - s
Dn + s = c
c = Dn +s
To solve for c in the equation D=c-s/n, isolate c by multiplying both sides by n, then rearrange the terms and divide by (n-D).
Explanation:To solve for c in the equation D=c-s/n, we need to isolate c. We can start by multiplying both sides of the equation by n to eliminate the fraction:
nD=cn-(s/n)(n)
Simplifying further, we get:
nD=cn-s
Next, we can bring the term cn to the left side of the equation by subtracting cn from both sides:
nD-cn=-(cn-s)
Rearranging the terms, we have:
-cn+nD=-(cn-s)
Factoring out c from the left side, we get:
c(n-D)=cn-s
Finally, we can solve for c by dividing both sides of the equation by (n-D):
c=(cn-s)/(n-D)

a map shows the town where niko lives. the actual distance from niko's house to his school is 3miles, and measures one-half inch on the map. the actual distance
Answer:
4 miles would be 2-thirds inch on the map.Step-by-step explanation:
The entire question is:
A map shows the town where Niko lives. The actual distance from Niko's house to his school is 3 miles and measures one-half inch on the map. The actual distance from Niko's school to the library is 4 miles. How long is this distance on the map?
To solve this problem, we can apply the rule of three, if 3 miles are one-half inch on the map, how long would be on the map for 4 miles.
[tex]x=4miles\frac{\frac{1}{2}in }{3miles}=4\frac{1}{6}in=\frac{2}{3}in[/tex]
Therefore, 4 miles would be 2-thirds inch on the map.
The actual distance of 4 miles would be 2-thirds inch on the map.
What is the distanceIf 3 miles is shown by one-half inch on the map, then to find the length on the map for 4 miles, you can set up a proportion:
(3 miles) / (1/2 inch) = (4 miles) / x
Now, cross-multiply:
3 * x = 4 miles * (1/2 inch)
3x = 2 miles * inch
So , divide both sides by 3 to find the length on the map (x):
x = (2 miles * inch) / 3
x = 2/3 inch
So, the correct length on the map for 4 miles is indeed 2/3 inch.

Answer:
-13F is less than -12F, and -9F is greater than -12F
Step-by-step explanation:
You can prove this because in the problem is states that -13F < -12F < -9F
If you utilize this, you find that the first statement is quite obvious:
-13F is less than -12F
The second statement is a little trickier. Since in the original inequality is states that -12F < -9F, but you want to know the relationship between the switch, you would just flip the sign in the middle, getting you:
-9F is greater than -12F
You could also prove this simply with the rules of negative values (which work inversely from positives).
Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.
A. Write an expression to show the total amount of money Maggia spent
B. If Maggie bought 4 CDs and 3 books, how much money did she spend?
Answer:
A: Spent = 12c + 7b + 24
B: 93 dollars
Step-by-step explanation:
Cost = 12*c + 7*b + 24
If c = 4 and b = 3 then the total cost is
Cost = 12*4 + 7*3 + 24 Substitute and combine factors
Cost = 48 + 21 + 24 Combine Terms
Cost = 93 dollars Answer
Maggie's total spending is represented by the expression 12c + 7b + 24. When purchasing 4 CDs and 3 books, plus a purse, she spent $93.
Explanation:The total amount of money Maggie spent can be represented by the expression: c CDs at $12 each + b books at $7 each + 1 purse at $24.
So, the expression is 12c + 7b + 24.
Given that Maggie bought 4 CDs and 3 books, the total amount spent is calculated as follows:
For CDs: 4 CDs × $12/CD = $48For books: 3 books × $7/book = $21For the purse: $24 (since only one purse was bought)Adding these amounts together gives us: $48 + $21 + $24 = $93.
Therefore, Maggie spent a total of $93 for 4 CDs, 3 books, and a purse.

78 = -2(m + 3) + m
Question 1 options:
–42
–72
–84
–28
Hey there!!
Equation given :
... 78 = -2 ( m + 3 ) + m
... 78 = -2m - 6 + m
... 78 = -m - 6
... 78 + 6 = -m
... 84 = -m
... m = -84
Hope my answer helps!!
Hello there!
The answer should be the third option C.
[tex]78 = -2(m + 3) + m[/tex]
First you had to simplify from both sides of the equations.
[tex]78=-2(m+3)+m[/tex]
[tex]78=(-2)(m)+(-2)(3)+m[/tex]
[tex]78=-2m+-6+m[/tex]
[tex]78=(-2m+m)+(-6)[/tex]
[tex]78=-m+-6[/tex]
[tex]78=-m-6[/tex]
Then you can flip by the equation.
[tex]-m-6=78[/tex]
Add by 6 from both sides.
[tex]-m-6+6=78+6[/tex]
[tex]-m=84[/tex]
Divide by -1 from both sides.
[tex]\frac{-m}{-1}=\frac{84}{-1}[/tex]
Simplify should be the correct answer.
[tex]m=-84[/tex]

Find the product.
6 x 500 = 6 x (blank) hundreds
= (blank) hundreds
= (blank)
**needing the “blanks” answered/solved.
The first blank should contain the number 50. The second blank should contain the number 300 which represents hundreds. Lastly, the third blank should contain the number 30,000 when converted back from hundreds.
Explanation:The original equation given is: 6 x 500. We can re-write this first in terms of hundreds as: 6 x (5,000/100) which means 6 times 50 hundreds. Hence, the first blank is 50.
Subsequently, you would find the product of 6 x 50 hundreds = 300 hundreds. Therefore, the value for the second blank is 300.
Finally, you would turn 300 hundreds back into a standard number by multiplying 300 by 100, which equals 30,000. So, the third blank would be 30,000.

A dance school allows a maximum of 15 students per class. If 112 students sing up for dance class, how many classes does the school need to offer to accommodate all the students?
The answer is 8.
In order to accommodate (or provide space for) all students, with the maximum students per class being 15, there needs to be at least enough for 112. A way to figure this out is 112 / 15 (the total amount of people signed up divided by the amount per class). The quotient is 7.466..., which does not work since you cannot have a 0.466... of a human in a class. This means you must round to the nearest whole number. If there were more students it could accommodate 8 more being that 15 * 8 is 120, but in this case there are only 112.

Melissa has completed 85% of the bike course by riding 51 out of 60 miles. This was calculated by dividing the distance ridden by the total distance and multiplying by 100.
To find out what percentage of the bike course Melissa has ridden, we need to divide the distance she has ridden by the total distance of the course and then multiply by 100 to get the percentage. Melissa has ridden 51 miles of the 60 miles long course. Therefore, the percentage of the course she has ridden is calculated as follows:
Divide the distance ridden by the total distance: 51 miles / 60 miles.Multiply by 100 to convert the decimal to a percentage: (51 / 60) * 100.When we perform this calculation, we get:
(51 / 60) * 100 = 85%
So, Melissa has ridden 85% of the bike course.

1. What is the value of a?
-2(a - 8) + 6a = 36
Remember to follow PEMDAS. First, distribute -2 to all terms within the parenthesis
-2(a - 8) = -2a + 16
-2a + 16 + 6a = 36
Simplify. Combine like terms
6a - 2a = 4a
4a + 16 = 36
Isolate the a. Do the opposite of PEMDAS. First, note the equal sign. What you do to one side, you do to the other.
Subtract 16 from both sides
4a + 16 (-16) = 36 (-16)
4a = 36 - 16
4a = 20
Divide 4 from both sides
4a/4 = 20/4
a = 20/4
a = 5
5 is your answer for a
-------------------------------------------------------------------------------------------------------------------
2. What is the value of n in (3n + 6)/3 = 15
Remember to do the opposite of PEMDAS. Note the equal sign. First, multiply 3 to both sides
(3n + 6)/3(3) = 15(3)
3n + 6 = 45
Next, subtract 6 from both sides
3n + 6 (-6) = 45 (-6)
3n = 45 - 6
3n = 39
Finally, isolate the n. Divide 3 from both sides
3n/3 = 39/3
n = 39/3
n = 13
13 is your answer for n

Todd is at the grocery store purchasing ingredients for homemade granola. He needs x ounces of almonds, which are priced at m dollars per ounce in the baking section. The total cost of the other ingredients is b dollars. The following expression represents the total amount of money that Todd will spend on all of the granola ingredients. Todd later finds almonds in the bulk section that are half the price of those in the baking section. If he purchases the almonds in the bulk section, which of the following statements are true about the given expression?
Answer:
The correct statements are :
1. The value of mx will change.
2. The value of m will change.
3. The value of mx+b will decrease.
Step-by-step explanation:
The question is as shown in the attached figure.
Todd needs x ounces of almonds, which are priced at m dollars per ounce in the baking section. So, price of x ounces becomes = mx
The total cost of the other ingredients is b dollars.
Hence, total cost is given as = mx+b
Now, Todd later finds almonds in the bulk section that are half the price of those in the baking section.
So, now price = m/2
And total price for 'x' ounce = (mx/2 + b) dollars.
So, if Todd purchases the almonds in the bulk section, the total cost will decrease.
The correct statements are :
1. The value of mx will change.
2. The value of m will change.
3. The value of mx+b will decrease.

To solve the problem, an algebraic equation is set using the given conditions. After solving it, it's established that Nate has 28 one-dollar bills and 21 five-dollar bills.
Explanation:Let's solve the problem in two steps. First, we already know the total sum of money Nate has, which is $267, and the value of his eleven $10 bills, which is $110. So, we subtract $110 from $267, leaving $157 to be divided among the $5 and $1 bills.
Next, we assign variables to the unknowns. Let's call the no of $1 bills 'x' and no of $5 bills ''x-7'. A $5 statement is worth five $1 bills so that we can rewrite 'x-7' as '5(x-7)'. Setting up the equation 5(x - 7) + x = 157 and solving for x gives us 28.
The problem-solving strategy here is using a system of equations to solve a money problem. So Nate has 28 one-dollar bills and 21 five-dollar bills (28-7).

Iman has 6 packs of cards . Mateo has 10 packs of cards. between the two of them, they have 128 sports cards . how many sports cards does each child have? explain your answer?
iman has 48 cards and mateo has 80 cards
To find out how many sports cards Iman and Mateo each have, we can set up an algebraic equation based on the total number of cards and the packs they have. After solving the equation, we find that Iman has 48 sports cards, and Mateo has 80 sports cards.
Explanation:The student's question pertains to a problem involving arithmetic and algebra. Iman and Mateo have a total of 128 sports cards combined. The question asks us to find out how many sports cards each child has. Let's call the number of cards that each pack contains 'x'. Therefore, Iman's cards can be represented as 6x and Mateo's cards as 10x. According to the information, 6x + 10x equals 128.
Combining the terms gives us 16x = 128. We can find 'x' by dividing both sides of the equation by 16, which gives us x = 8. Therefore, Iman has 6 packs times 8 cards per pack, which results in 48 cards, and Mateo has 10 packs times 8 cards per pack, adding up to 80 cards.
Iman has 48 sports cards and Mateo has 80 sports cards.
