The cost of producing n necklaces is p(n)=15n + 60. The necklaces cost $30, which can be represented by c(n) = 30n. For how many necklaces does the cost of production equal the sales?
Answer:
4 necklaces
Step-by-step explanation:
when p(n)=c(n), the cost equals the sales
15n+60=30n
60=15n

Answer: You can’t really add them
Step-by-step explanation: Since 4x has a variable, and 4x and 4 aren’t like terms, you CAN NOT add them together. I’m not sure if that was what you were looking for.
The lines represented by the equations 20y−24x=−20 and 5y−6x=−5 are...
a)perpendicular
b)the same line
c)neither parallel nor perpendicular
d)parallel
Answer:
parallel i think
Step-by-step explanation:
parallel because it's a unknown error
Answer:
Choice B
Step-by-step explanation:
The best way to compare two lines is to solve for y.
The first equation:
For [tex]20y-24x=-20[/tex] the first thing we should do is add the 24x on both sides which will cancel out itself on the left side [tex]20y=24x-20[/tex]. Now all we have to do is divide the 20 on both sides to leave us with [tex]y=\frac{6}{5}-1[/tex].
The second equation:
For [tex]5y-6x=-5[/tex] the first thing we should do is add the 6x on both side which will cancel itself on the left side [tex]5y=6x-5[/tex]. Now all we have to do is divide the 5 on both sides to leave us with [tex]y=\frac{6}{5}x-1[/tex].
Now for the comparison:
They are the same exact line. If you were to graph them they would overlap each other.

Madison is given rectangle ABCD with one diagonal BD
Answer:
i. Rotate
ii. Translates
Step-by-step explanation:
Rigid transformations are the methods required in which the orientation, dimension, position, or size of a given figure can be transformed. Some types of rigid transformation are: rotation, translation, reflection, etc.
From the given question, the two rigid transformation procedure required for Madison to prove that ΔABD ≅ ΔCDB by rigid transformations are: rotation and translation.
Madison decides to rotate ΔABD [tex]180^{o}[/tex] about point B to create triangle A'B'D'. Next she translates A'B'D' along diagonal BD until point B' from ΔA'B'D' lines up with point d from ΔCDB.
Therefore,
ΔABD ≅ ΔCDB
Find the solution to the equation
16.2 + n = 16
Answer:
-0.2
Step-by-step explanation:
to find n you need to get it all by itself so you subtract 16.2 from both sides so on the left side it cancels out and on the right side it equals -.02 which is then equal to n which is your answer

Solve the absolute value equation.
│4x + 3│= 3
A. x = 0 or x = negative three over two
B. x = 0 or x = 3 over 2
C. x = 1 or x = negative three over two
D. x = 1 or x = 3 over 2
Answer:
A
Step-by-step explanation:
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |4x+3|
For the Negative case we'll use -(4x+3)
For the Positive case we'll use (4x+3)
-(4x+3) = 3
Multiply
-4x-3 = 3
Rearrange and Add up
-4x = 6
Divide both sides by 4
-x = (3/2)
Multiply both sides by (-1)
x = -(3/2)
Which is the solution for the Negative Case
(4x+3) = 3
Rearrange and Add up
4x = 0
Divide both sides by 4
x = 0
Which is the solution for the Positive Case
x=-3/2
x=0
The solution of the absolute equation │4x + 3│ = 3 will be 0 and - 3/2. Then the correct option is A.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The absolute function is also known as the mode function. The value of the absolute function is always positive.
f(x) = |x - h| + k
The absolute function is given as,
│4x + 3│ = 3
Simplify the equation, then we have
│4x + 3│ = 3
4x + 3 = ± 3
4x = - 3 ± 3
For positive signs, then we have
4x = - 3 + 3
4x = 0
x = 0
For negative sign, then we have
4x = - 3 - 3
4x = - 6
x = - 3/2
The solution of the absolute equation │4x + 3│ = 3 will be 0 and - 3/2. Then the correct option is A.

This equation produces a vertical line that will go through (-7,0) and (-7,8) along with all other real y values.
Jamal has a plan to save money for a trip. Today, Jamal deposits $10.00 into the savings account. Each week, Jamal will add $5.00 to the amount that is deposited into the savings account. The table below shows the relationship between the number of weeks and how much money, in dollars, Jamal deposits into the savings account.
Let f(x)represent the amount of money Jamal deposits into his savings account at the end of x weeks. Based on the table, what is f(10)?
Answer:
y = 5x + 10
Step-by-step explanation:
using the formula y = mx + b you can easily find the answer.
where
m = the rate of change
b = constant
x = the independent variable
Since he has the initial $10.00 added to the account, we know that is the constant since he won’t be adding that anymore.
Since he will be adding $5.00 to the account every month we know that this is the rate of change.
the variable x will change depending on the number of months passed.
Therefore we can create the equation:
y = 5x + 10

Helen draw a massive circle she the
Damari wants to trim the circular concrete
mural with outdoor rope lighting. The mural has a
diameter of 45 feet. One rope has a length of 50
ft. Each strand costs $39.99. How much will
Damari spend in order to trim the mural with
rope lighting? Use 3.14 to approximate .
Answer:
First, let's find the perimeter of the concrete mural.
A circle of diameter d, has a perimeter:
p = d*pi
where pi = 3.14
the concrete mural has a diameter of 45 ft, then it's perimeter is:
P = 45ft*3.14 = 141.3 ft
One rope has a length of 50ft, and costs $39.99.
Let's find the number of ropes that Damari needs to use, so let's divide the perimeter in lengths of 50ft:
N = 141.3ft/50ft = 2.826
Then Damari needs 2.826 ropes, but she can not buy 0.826 of a rope, then we should round it up to 3 ropes.
Then she needs to buy 3 ropes, and she will pay 3 times $39.99, this is:
Cost = 3*$39.99 = $119.97

Colin invests £9100 into his bank account.
He receives 2.5% per year simple interest.
How much will Colin have after 3 years?
Give your answer to the nearest penny where appropriate.
Answer:
The total amount accrued, principal plus interest, from simple interest on a principal of $9,100.00 at a rate of 2.5% per year for 3 years is $9,782.50.
Step-by-step explanation:
Principle amount = P = £9100
interest rate = r = 2.5% per year
Time period = t = 3
Simple Interest = 9100 × 2.5% × 3 = £682.5
Total amount = Principal amount + Simple interest
= 9100 + 682.5
= £9782.5
Therefore, the total amount accrued, principal plus interest, from simple interest on a principal of £9,100.00 at a rate of 2.5% per year for 3 years is £9,782.50.

the observation of an underground data in their ascending order are 12,15,X,19,28. if the median of the data is 18 find the value of x
Answer:
The value of x = 18
Step-by-step explanation:
Given the data set
[tex]12,15,x,19,28[/tex]
Given that the median of the data is 18.We know that the median is the middle number in a data set when the data points are in ascending order.As the given data is already in ascending order.
Please observe that the data set has an odd number of data points, meaning that the middle number is the median of the data is 18.As 'x' is the middle number, thus it represents the median value.
Therefore, the value of x = 18
