Answer:
x = - 1 / 24
Step-by-step explanation:
-6 ( 6x - 1 ) + 9 = 36x + 18
First, solve the brackets.
-36x + 6 + 9 = 36x + 18
Then, subtract 36x by both sides.
-36x - 36x + 6 + 9 = 18
-72x + 15 = 18
Now, Subtract 15 by both sides.
-72x = 18 - 15
-72x = 3
Now divide both sides -72 by both sides.
x = - 3 / 72
x = - 1 / 24
The Sales Manager for Chicken Shack restaurants is studying the sales figures for two new varieties of chicken sandwiches recently introduced at eight of its restaurants. For four weeks, three restaurants have been selling lemon-roasted chicken sandwiches. The other five restaurants have been selling barbecued chicken sandwiches for three weeks. During the testing period, 6,000 lemon-roasted chicken sandwiches were sold, and 7,200 barbecued chicken sandwiches were sold. Which of the two new chicken sandwiches should the sales manager report as having the better sales?
Using the average sales per restaurant, the sales manager should report the Lemon-roasted chicken sandwiches as recording better sales performance than the Barbecued chicken sandwiches.
What is the average?The averages represent the total sales generated at the lemon-roasted and barbecued restaurants, respectively, divided by the number in each group.
The average is the same as the mean of a data set. It is computed by the mathematical operations of addition and division.
Lemon-roasted Barbecued
The number of restaurants 3 5
Total sales during the testing period 6,000 7,200
Average sales per restaurant 2,000 1,440
Based on the average sales, the sales manager should report that the lemon-roasted chicken sandwiches are outperforming the barbecued restaurants.

A triangle has an angle that measures 111°. The other two angles are in a ratio of 6:17. What are the measures of those two angles?
Answer:
18 and 51
Step-by-step explanation:
the sum of the two other angles would be 69 degrees because there has to be 180 degrees in a triangle
given that we can create the equation 6x + 17x = 69 and solve for x
x = 3
so now we can plug in each part of that equation and find out the two angles

Firslty, we need to find the function, whcih we can do by substituting one into the other:
[tex]f(g(x))=2(g(x))^2-1=2(\sqrt[]{x-2})^2-1=2(x-2)-1=2x-4-1=2x-5[/tex]Now, for the domain we have more complicated approach.
We first have to find the domain for both f(x) and g(x).
The domain of f(x) is all real number, because it is a quadratic polynomial.
The domain of g(x) is all the real numbers except the x values that makes the square root interior negative, so all real numbers so that:
[tex]\begin{gathered} x-2\ge0 \\ x\ge2 \end{gathered}[/tex]Now, the domain of the composite function f(g(x)) is the set of all the values of x in the domain of g(x) such that the corresponding g(x) is in the domain of f(x).
Since the domain of f(x) is all real numbers and g(x) is a real number function, all the values of g(x) will be in the domain of f(x), so we just need to check the values of x that are in the domain of g(x).
The domain of g(x), as we saw, is:
[tex]D=\mleft\lbrace x\mright|x\ge2\}[/tex]And any value of x will give a g(x) that will be in the domain of f(x) so, the domain of f(g(x)) is:
[tex]D=\mleft\lbrace x\mright|x\ge2\}[/tex]So, the correct alternative is:
[tex]\begin{gathered} f(g(x))=2x-5 \\ D\colon\mleft\lbrace x\mright|x\ge2\} \end{gathered}[/tex]√15/√3 pls answer this for me so i can chill

A woman has twice as many dimes as quarters in her purse. if the dimes were quarters and the quarters were dimes, she would have $1.20 more than she has now. how many of each type of coin does the woman have?
The number of Quarter coins that she has is 8 and the number of Dimes is 16.
It is given in the question that the woman has twice as many Dimes as the quarters in her purse.
We know that the value of Dimes is 0.10$ and the value of Quarters is
0.25 $
Let the number of Quarter coins is y and the number of Dimes coin be u.
According to the question above,
u = 2y equation (i)
The total value z = 0.25y + 0.10u
Putting here the value of u from equation (i) we have,
z = 0.25y + 0.10(2y)
⇒ z = 0.25y + 0.20y
⇒ z = 0.45y equation (ii)
Now it has been mentioned that if the Dimes were Quarters and the Quarters were the Dimes, she would have $ 1.20 greater than she has now.
So we have,
z + 1.2 = 0.25u + 0.10y
Putting the value of u from above eqation (i),
z + 1.2 = 0.25(2y) + 0.10y
⇒ z + 1.2 = 0.50y + 0.10 y
⇒ z + 1.2 = 0.60y
Putting the value of z from equation (ii)
⇒ 0.45y + 1.2 = 0.60y
⇒ 0.45y - 0.60y = - 1.2
⇒ -0.15y = - 1.2
⇒ y = [tex]\frac{-1.2}{-0.15}[/tex]
⇒ y = 8
Therefore u = 2y
⇒ u = 2 x 8 = 16
Hence the number of Quarter coins is 8 and the number of Dimes is 16

Which of the following is most likely to be a relative maximum for this graph?
8-
(-1.0) (20)
-8 -84
6
Answer:it’s (-1,8)
Step-by-step explanation:
y is inversely proportional to the square root of x.
When x = 16, y = 10.
What does x equal when y = 8?
Answer:
x = 25 when y = 8
Step-by-step explanation:
If y is inversely proportional to square root of x we write it as
[tex]y \propto \dfrac{1}{\sqrt{x}}[/tex]
This is also equivalent to
[tex]y = k \dfrac{1}{\sqrt{x}} \;\;\;\;\ \text{ [1]}[/tex]
where k is a constant known as the constant of proportionality
Given y = 10 when x = 16 we can find k by substituting for y and x in [1]
[tex]\rightarrow 10 = k\dfrac{1}{\sqrt{16}}\\\\\rightarrow 10 = k \dfrac{1}{4}\\\\\drightarrow 40 = k \:\:\:\: \text{by multiplying both sides by 4}\\\\\text{which can be written as }\\\\k = 40\\[/tex]
So constant of proportionality k = 40
To find x when y = 8, substitute y and k in [1] to get
[tex]y = k \dfrac{1}{\sqrt{x}}\\\text{Multiply both sides by \sqrt{x} and divide by y at the same time to get}\\\\\sqrt{x} = \dfrac{k}{y}[/tex]
Dividing both sides by y and multiplying by √x gives us
[tex]\sqrt{x} = \dfrac{k}{y}\\\\\text{Substituting k = 40, y = 8}:\\\\\sqrt{x} = \dfrac{40}{8}\\\\\sqrt{x}= 5\\\\\text{Squaring both sides: }\\\\(\sqrt{x})^2 = 5^2\\\\x = 25 \;\;\;\text{since $(\sqrt{x})^2$ = x}[/tex]
The answer is
x = 20
Formulate y=k/x based on the following criteria.
Replace: 10= k/16
Change the sides so that k/16 = 10.
Subtract the coefficient of the variable from both sides of the equation: k = 10×16
Determine the quotient or product: k = 160
Replace with y = 160/x.
Replace with: 8 = 160/x
The denominator cannot be zero if the fraction is defined: as x ≠ 0
As the domain, append the inequality: 8= 160/x, x≠0
Divide the common denominator by both sides of the equation: 8x = 160x/x, x≠0
8x=160x/x, where x ≠ 0. Reduce the fraction.
By the variable's coefficient, multiply both sides of the equation (x=160÷8, x ≠ 0).

I really need help please figure this out I need it by Monday October 17 2021 please help me thank you
The amount of money that June has is $40 and Maria has $400. The total amount is $440.
What is the total amount?From the information, John has $400 June has 1/10 of that and June has 0.1 of Maria’s money.
Therefore the amount that June has will be:
= 0.1 × John's money
= 0.1 × 400
= 40
June has 0.1 of Maria’s money. Let Maria's money be x. Therefore, 0.1 × x = 40
0.1x = 40
Divide
x = 40 / 0.1
x = 400
Maria's money = 400
Therefore, the total amount that they have will be:

The calculated answer after simplification in which Ryan has number of baseball cards is: 357 cards
How to simplify statement problems?
In mathematics, the statement based problems can be solved by forming the equations. And later, simplify those equation by equating to each other. This method is very common for the complicated problems to make the calculation easy.
According to the question, Ryan collected 2650 cards. In which, he has more baseball cards compared to football cards.
Now, let us assume, baseball cards be 'B'; football cards be 'F' and hockey cards be 'H'.
As per the question, the formed equation from the statement for the simplification is:
B + F + H = 2650
3B = F and H + 150 = F
Substituting above values in the formed equation to get the simplify answer,
B + 3B + 3B - 150 = 2650 ⇒ 7B = 2500 ⇒ B = 357
Now, the value of football cards is: F = 3(357) = 1071
And, the value of hockey cards is: H = 1071 - 150 = 921
