The solution of the linear equation −2.4(m − 2/3) = −9 will be 4 ⁵/₁₂.
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 definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
−2.4(m − 2/3) = −9
Simplify the equation, then we have
−2.4(m − 2/3) = −9
m - 2/3 = 9/2.4
m - 2/3 = 15/4
m = 15/4 + 2/3
m = 53 / 12
m = 4 ⁵/₁₂

Caleb wa out at a retaurant for dinner when the bill came. Hi dinner came to $21. He wanted to leave a 31% tip. How much wa hi meal plu the tip, before tax, in dollar and cent
If Caleb dinner was for $21 then the total bill including tip will be $27.51 .
Caleb went out for the dinner ;
the amount for the dinner = $21 ;
the percent of tip that Caleb want to leave = 31% ;
that means ; tip amount = 31% of dinner amount ;
So , tip amount = 31% of $21 = 0.31 × 21 = $6.51 ;
the tip amount = $6.51 ;
the total bill = bill for dinner + tip amount = $21 + $6.51 ;
= $27.51 .

To solve the given inequality, the solution is: x < 5. So, the correct answer is option C.
Here, we can solve the inequality x + 2 > 3x - 8 as follows :
We get 2 on both sides of an inequality by the process of subtraction
or, x + 2 - 2 > 3x - 8 -2
or, x > 3x -10
We get 10 on both sides of an inequality by the process of addition
or, x +10 > 3x -10 + 10
or, x + 10 > 3x
We get x on both sides of an inequality by the process of subtraction
or, x + 10 -x > 3x -x
or, 10 > 2x
We get 2 into both sides of an inequality by the process of division
or, 5 > x
Therefore, x < 5.

pls help asap i can’t pass this class without passing this test
To answer this question, we need to first multiply the left side of the given equation and write it as the difference of two squares. This can be done by using the difference of squares formula, which states that the difference of two squares can be written as the product of the square of the sum and the square of the difference.
The left side of the given equation can be written as:
(csc0+1)(csc0-1)
We can then apply the difference of squares formula to this expression to get:
(csc0+1)(csc0-1) = (csc0+1)(csc0-1)
Now, we can see that this expression is equivalent to cot 0 using the Pythagorean Identity. This identity states that the sum of the squares of the cosecant and cotangent of an angle is equal to 1. In this case, since (csc0+1)(csc0-1) = cot 0, we can use the Pythagorean Identity to rewrite the left side of the equation as (csc0^2 + cot0^2) = 1, which is equivalent to cot 0.
Therefore, the correct answer is C. Pythagorean Identity
You can represent the perimeter of a shape with the two expressions 6x - 8 and 4(1.5x - 2). What does 4(1.5x -2) tell you about the shape that 6x - 8 does not?
The expression 6x-8 represents the perimeter of a shape in terms of the length of one of its sides, while the expression 4(1.5x-2) represents the perimeter of the same shape in terms of the length of its diagonals. Therefore, the expression 4(1.5x-2) provides additional information about the shape that is not contained in the expression 6x-8. Specifically, the expression 4(1.5x-2) tells us that the length of each diagonal of the shape is equal to 1.5 times the length of one of its sides minus 2. This information allows us to determine the lengths of the diagonals of the shape, which is not possible with the information provided by the expression 6x-8.

variability.
In statistics, variability refers to the spread or spread of a data set. It is a measure of how much the data points in the dataset differ from each other and from the mean (mean) of the data.
There are several ways to quantify dataset variability. A common measure of variability is range. This is the difference between the highest and lowest values in the dataset. Another measure of variability is variance. This is a measure of how far the data points are from the mean. Standard deviation is another measure of variability calculated by taking the square root of the variance.
In addition to these measures of variability, there are other statistical techniques that can be used to summarize the spread of datasets, such as Box plot and histogram. These techniques help visualize data variability and identify outliers.

for a random sample of 90 such pairs, where is the sampling distribution of x centered, and what is the standard deviation of the x distribution?
The standard deviation of the x distribution for a random sample of 90 pairs will be 0.168 .
As stated in the assertion
The sample n has been provided, and we need to determine the sample's standard deviation.
For this reason, we know that the standard deviation of the sample is equal to the population's standard deviation divided by the square root of the sample's length.
The value of alpha is given as,
alpha = 1.6.
Assume that for a specific type of aluminum alloy sheet, X is the sample mean Young's modulus for a random sample of 90 sheets, and
s = alpha/ 90 s
= 1.6/9.48 s
= 0.168
Therefore, 0.168 is the x distribution's standard deviation.

Jen Butler ha been pricing Speed-Pa train fare for a group trip to New York. Three adult and four children mut pay $129 Two adult and three children mut pay $92 Find the price of the adult' ticket and the price of a child' ticket
The price of the adult ticket is calculated to be $19 and the price of a child ticket is calculated to be $18.
The price of the adult ticket and the price of a child ticket can be calculated by using algebraic expressions as follows;
Considering adult ticket price = y and child ticket price = x;
The algebraic equations for tickets can be given as follows;
3y + 4x = $129
2y + 3x = $92
Now we can calculate y as follows;
3y + 4x = 129
3y = 129 - 4x
y = 129 - 4x / 3
Adding this value of y in the second equation as follows;
2y + 3x = 92
2(129 - 4x / 3) + 3x = 92
258 - 8x / 3 + 3x = 92
258 - 8x / 3 = 92 - 3x
258 - 8x = 3(92 - 3x)
258 - 8x = 276 - 9x
9x - 8x = 276 - 258
x = $18
Hence the price of a child ticket is $18 and the price of an adult ticket can be determined as follows;
2y + 3x = 92
2y + 3(18) = 92
2y + 54 = 92
2y = 38
y = 38 / 2
y = $19
Therefore the price of an adult ticket is $19.

What is meant by geometric mean theorem?The relationship between the height on the hypotenuse of a right triangle and the two line segments it generates on the hypotenuse is described by the right triangle altitude theorem, also known as the geometric mean theorem, which is a consequence of elementary geometry. It claims that the altitude is equal to the geometric mean of the two segments.The later version provides a method for squaring a rectangle using a ruler and compass, which entails creating a square with the same area as the rectangle in question.Since the inverse of Thales' theorem guarantees that the hypotenuse of the right angled triangle is the diameter of its circumcircle, the theorem may also be seen as a specific example of the intersecting chords theorem for a circle.Given data :
m∠XBC = m∠BAC + m∠BCA,

A line pae through point (-6,5) and ha a lope of 2. Write an equation in AxBy=C form for thi line
The standard form of the linear equation of a straight line is given as
2x - y + 17 = 0
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
y=mx+c; where y and x stand for the respective axis's; 'm' represents the slope while 'c' represents the constant.
Let the point through which the line passes be P
Then, P= (-6,5)
m= 2
The equation of a straight line as a single point form can be found using the formula:
y-y1=m(x-x1)+c
y-(5) = 2(x-(-6))+c
y -5= 2(x+ 6)+c
Taking LCM
y - 5 =2(x+6)
on cross multiplying we get:
y - 5 = 2x + 12
y = 2x + 12 + 5
2x - y + 17 = 0
Thus, Equation of the line comes out to be 2x - y + 17 = 0
