The answer of the algebraic equation is x = 30

An algebraic equation is when two expressions are set equal to each other, and at least one variable is included

Given: (x-4/5)-(x+1/6)=1/3

(x-4/5)-(x+1/6)= 1/3

The LCM of 5 and 6 is 30

[6(x-4) - 5(x+1)]/30 = 1/3

cross multiply:

[6(x-4) - 5(x+1)] = 30/3

Expand the bracket:

6x -24 -5x -5 = 10

Add/subtract like terms:

x - 29 = 10

x = 10 + 29

x = 30

Thus, the answer is x = 30

Step-by-step explanation:

So first up Expand ( - [tex]\frac{4}{5}[/tex]) -(x + [tex]\frac{1}{6}[/tex]): - [tex]\frac{29}{30}[/tex]

so 1 more thing you have to remember their will be no answer so You then have to add this up - [tex]\frac{29}{30} =\frac{1}{3}[/tex]

so last step Multiply by LCM "Least common multiply"

so -29 = 10

and we do not have an answer because The sides are not equal so if you need an answer  it will be

s varies directly as t:

If s is 20 when t is 4, find the value of k:

The equation is:

When s is 30, then t is:

Answer:

Thus, t = 6 if s = 30.

Step-by-step explanation:

Given that,

→ The value of s is 20 when t is 4.

Now value of s when t is 1,

→ s = (20/4)t

→ [ s = 5t ]

Then value of t when s is 30,

→ 5t = 30s

→ t = (30/5)s

→ t = 30/5

→ [ t = 6 ]

Hence, the value of t is 6.

We can infer from the graph that is attached that (D) the function decreases when x is between -6 and 0.

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.

The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

So, consider the given chart.

For a certain period of points, the function is decreasing.

Attach the point to the x-axis and we will get that between the x-axis -6 and 0, the function is decreasing.

The Hill Co. should not further produce Product P from Product P.

We need to calculate the incremental cost and incremental revenue of producing P to understand the profit or loss margin.

Incremental revenue = Selling product of P - Selling product of O

Incremental revenue = 82 - 60

Performing subtraction

Incremental revenue = $22

Incremental cost = Cost of producing O - Cost of producing P

Incremental cost = 42 - 13

Performing subtraction

Incremental cost = $29

It is clear that incremental cost is more than incremental revenue, so Hill Co. should not continue the production.

The probability that all four strawberry pieces will be received by the same child 9/10 outcome.

Total piece of candy = 40

Mint flavor = 36

Strawberry = 04

There are 36 + 04 = 40 total outcomes for the chocolate pick.

There are 36 outcomes resulting in you picking a mint candy.

Probability is the number of outcomes you’re testing for divided by the number of total outcomes. So in this case that’s 36/40 or 4/5 . And also,  

04 /40 = 1/10

Tomika and Mark claim a medical deduction in the amount of $1,839.8.

To determine how much Tomika and Mark can claim as a medical deduction, you first need to calculate the number of medical expenses that are covered by their insurance.

The first step is to calculate medical insurance :

Medical insurance = 7.5 % of $101,598

Medical insurance = 7.5% x $101,598

Medical insurance =  $7,619.88.

Medical deduction claim = $7,619.88 - (100% - 60%)x $3,800

Medical deduction claim = $7,619.88 - 40% x $3,800

Medical deduction claim = $7,619.88 - $1,520

Medical deduction claim = $6,099.88

Answer:

The diagram shows a line of reflection, labeled as "line r," and a point B on one side of the line. The image of point B, labeled as B', is shown on the other side of the line.

If point A is on line r, then the image of A would be A itself because a reflection in line r means that all points on the line remain unchanged.

If point B is not on line r, then line r would be the perpendicular bisector of line segment BB'. This means that line r would pass through the midpoint of line segment BB' and be perpendicular to it. The image of point B would be on the opposite side of line r from the original point B, but the distance between B and B' would remain the same.

The solutions for the given equation are [tex]2+\sqrt{31}[/tex] and [tex]2-\sqrt{31}[/tex]. These are calculated by applying the quadratic formula since the given equation is a quadratic equation.

The quadratic formula is used for finding the roots of a quadratic equation in the form of ax² + bx + c = 0.

The formula is,

x  = [tex]\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

The given equation is

x² - 27 = 4x

On rewriting the equation, we get

x² - 4x - 27 = 0

thus, it is in the form of ax² + bx + c = 0. So, this is a quadratic equation.

Then, applying the quadratic formula for finding roots is nothing but its solutions.

Where a = 1; b = -4; c = -27

⇒ x = [tex]\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

      = [tex]\frac{-(-4)\pm\sqrt{(-4)^2-4(1)(-27)} }{2(1)}[/tex]

The dimensions of the box with a volume of 1000 cm3 that has a minimal surface area are  10 cm* 10 cm*10 cm.

Let's define the dimensions of the box as x, y and z.  The surface area of the box is given by:  2(xy + xz + yz). We want to minimize the surface area.  Since the volume is 1000 cm3, we know xyz = 1000.  Therefore, the surface area of the box is given by:

2(xy + xz + yz) = 2(1000/x + 1000/y + 1000/z),  We need to minimize 2(1000/x + 1000/y + 1000/z) subject to xyz = 1000.  This is a constrained optimization problem.  We can solve this problem using Lagrange multipliers.  Let L(x, y, z, λ) be the Lagrangian given by:

L(x, y, z, λ) = 2(1000/x + 1000/y + 1000/z) + λ(xyz - 1000), To find the minimum, we need to find the critical points of the Lagrangian.  Taking the partial derivatives of L with respect to x, y, z, and λ, we get:

∂L/∂x = -2000/x² + λyz = 0

 ∂L/∂y = -2000/y² + λxz = 0

∂L/∂z = -2000/z² + λxy = 0  

∂L/∂λ = xyz - 1000 = 0

From the last equation, we get xyz = 1000.  Substituting this value in the first three equations, we get:

 ∂L/∂x = -2000/x² + 2000/x = 0

∂L/∂y = -2000/y² + 2000/y = 0  

∂L/∂z = -2000/z² + 2000/z = 0

Solving these equations, we get x = y = z = 10.  Therefore, the dimensions of the box with minimal surface area and volume of 1000 cm3 are x = y = z = 10 cm.

The probability that they finish within 10 minutes of each other here their times are independent

standard deviations, σ₁ = 4.8

let X₂ be a random variable as sam cleans the interior of each car.

standard deviations, σ₂ = 6.4

If the two random variables are normal, then their difference , X₂ - X₁ also be normal.

As two normal variables here are normally distributed, therefore the distribution of the difference between the two variables here is given as: X₂ - X₁ = X

with mean, μ = μ₂ - μ₁ = 2

standard deviations, σ = σ₁² + σ₂²

To any bivariate Normal distribution of (X₁,X₂) Thus the variable

Z = (X−μ)/σ = (X₂−X₁ −(μ₂ - μ₁))/(√σ₁² + σ₂²)

The probability here is computed as:

P( -10 < X₂ - X₁ < 10) = approx P(∣D∣<10)

where D is difference between their finishing times. Converting it to a standard normal variable, we have here:

= P( (-10 - 2) / 8 < Z < (10 - 2) / 8)

= P( -1.5 < Z < 1)

= P(Z < 1 ) - P(Z < -1.5)

The line that connects the coordinates (6, -1) and is parallel to the line denoted by the equation 8x + 3y = 15 has the standard form equation 8x + 3y = 45.

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

Standard version of the equation is Ax + Bx = C.

A, B, and C are constants where

In light of this, the slope intercept form y = mx + b

m = slope, and b = y-intercept

8x+ y = 15

3y= -8x+15

y= -8/3x + 5

slope = -8/3

The line passes through (6, -1)
