Answer:
D = [tex]\frac{n-5m^2}{5}[/tex]
Step-by-step explanation:
Given
n = 5(m² + D) ← distribute
n = 5m² + 5D ( subtract 5m² from both sides )
n - 5m² = 5D ( divide both sides by 5 )
[tex]\frac{n-5m^2}{5}[/tex] = D
The solution of the expression for the value of D will be D = (n - 5m²) / 5
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is n = 5(m² + D). The value of D will be calculated as below:-
n = 5(m² + D) ← distribute
n = 5m² + 5D ( subtract 5m² from both sides )
n - 5m² = 5D ( divide both sides by 5 )
(n - 5m²) / 5 = D
Therefore, the solution of the expression for the value of D will be D = (n - 5m²) / 5

Solve the inequality -2(4x-2)<-8x+4
Answer:
There are no solutions.
Step-by-step explanation:
−2(4x−2)<−8x+4
Step 1: Simplify both sides of the inequality.
−8x+4<−8x+4
Step 2: Add 8x to both sides.
−8x+4+8x<−8x+4+8x
4<4
Step 3: Subtract 4 from both sides.
4−4<4−4
0<0

POSSIBLE POINTS. 7 Two clothing stores are having a sale on all their dress shirts. Store A is charging $15 for each dress shirt. Store B is $18 for each shirt but giving customers a coupon for a $9 discount when they check out. Which of the following statements are true? There can be more than one correct answer.
Answer:
The statements are not provided, so i will answer in a general way.
Let's define the variable x as the number of dress shirts brought for some person.
In store A, each one costs $15.
Then the cost of x dress shirts will be:
A(x) = $15*x.
In store B, each one costs $18, but there is a coupon of $9, then we can write the cost in store B as:
B(x) = $18*x - $9.
Now we can find wich store will be cheaper for a given number x, by calculating the difference between A(x) and B(x).
D = A(x) - B(x)
If D is positive, means that B(x) is cheaper.
If D is negative, means that A(x) is cheaper.
If D is equal to zero, means that the cost is the same in both stores.
D = A(x) - B(x) = $15*x - $18*x + $9 = (-$3*x) + $9.
First, let's find for what value of x we have the same cost in both stores:
0 = (-$3*x) + $9.
$9/$3 = 3 = x.
Then for 3 dress shirts, the cost will be the same in each store.
Now, as the coefficient that multiplies x is negative, if we have x > 3, then D will be negative, and if x < 3, D will be positive.
then:
For x = 3, the cost is the same in both stores.
for x > 3, Store A is cheaper.
For x < 2, Store B is cheaper.

A square has a side length of (x+3) centimeters. If the perimeter is 24 centimeters, what is the side length of the square? (Hint: to find
the perimeter of a square, you add up all the lengths of the sides).
A.Зcm
B.7cm
C. 9cm
D.14cm
Answer:
3 cm
Step-by-step explanation:
4(x + 3) = 24
4x + 12 = 24
4x = 12
x = 3 cm
**multiply by 4 because a square has 4 equal sides***
Answer:
3
Step-by-step explanation:
A square has 4 equal sides
so
4(x+3) = perimeter = 24
4x+12 = 24
4x = 12
x=3

Answer:
Step-by-step explanation:
A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. Absolute value of a number on a number line is its distance from 0 on the number line .
Shawna and her best friend Keisha go shopping. The function p(x) = 3x4 + 2x3 − 4x2 + 21 represents how much money each girl spent based on the number of hours they were shopping. If Shawna and Keisha each go shopping for 2 hours, how much money did they spend together? $37 $69 $101 $138 Question 9(M
Answer:
$69
Step-by-step explanation:
Given the amount of money each girl spent based on the number of hours they were shopping modeled by the function p(x) = 3x4 + 2x3 − 4x2 + 21
To get how much they spend together if each go shopping for 2hours, we will substitute x = 2 into the given function as shown:
p(2) = 3(2)⁴ + 2(2)³ − 4(2)² + 21
p(2) = 3(16) + 2(8) − 4(4) + 21
p(2) = 48 + 16 − 16 + 21
p(2) = 48+21
p(2) = 69
Therefore they spend $69 together
Answer: 138$
Step-by-step explanation: 69$ is how much 1 girl spends. They both spend 138%$. Also, I took the test.
Mary owns a coffee shop. She charges $4.50 for a cup of coffee, and it costs her $1.25 to make each cup of coffee plus a $75 a day for other expenses. Write and solve an equation to determine how many cups of coffee, c, will Mary need to sell to break-even?
Answer:
Approximately 23 cups of coffee
Step-by-step explanation:
Break even = Fixed cost/Selling price - variable cost
Fixed cost = $75
Selling price = $4.50
Variable cost = $1.25
Break even = $75/$4.50 - $1.25
= 23.076923077
Approximately = 23
Therefore, Mary has to sell approximately 23 cups of coffee daily in order to break evem
