Ya me la pusieron a mi y soy muy bueno en matemáticas

Answer:

x = 1; y = 3

Step-by-step explanation:

Get the unknowns on one side of the equal sign and the known numbers on the other:

EQUATION 1: y = 2x + 1 (subtract 2x from both sides)

y -2x = 1

EQUATION 2: y = 6 -3x (add 3x to both sides)

y + 3x = 6

Now we have two simultaneous equations:

y -2x = 1

y + 3x = 6

subtraction gives -5x = -5 so x = 1

Substitute x = 1 into one of the original equations to find y.

y + 3x = 6 becomes y + 3 = 6, so y = 3

Their expertise will help optimize the water supply to the farmhouse, promoting efficient irrigation and reliable water access for agricultural activities.

A farmer wanting to have a water pipe installed from the water source to his farmhouse must consider various factors to ensure an efficient and reliable water supply. Here are some important considerations for the installation process:

1. Water Source: The farmer needs to identify a reliable water source that can provide sufficient water for agricultural needs. This could be a well, a nearby river or stream, or a municipal water supply.

2. Distance and Terrain: The farmer should measure the distance between the water source and the farmhouse. The length of the pipe required will affect the cost and feasibility of the installation. Additionally, the terrain between the source and the farmhouse must be assessed. If there are any hills, valleys, or obstacles in the way, it may require additional planning and equipment to overcome them.

3. Pipe Material: Selecting the right type of pipe material is crucial. Common options include PVC (polyvinyl chloride), HDPE (high-density polyethylene), or metal pipes. Factors such as durability, cost, and compatibility with the water source need to be considered.

4. Pipe Size: The pipe size will depend on the desired water flow rate and the pressure needed at the farmhouse. Calculating the required flow rate involves considering the water demand for irrigation, livestock, and household use. Consulting with an expert or a professional plumber can help determine the appropriate pipe size.

5. Pump System: In cases where the water source is at a lower elevation than the farmhouse, a pump system may be required to lift the water to the desired height. The type and capacity of the pump should be selected based on the total head (vertical lift) and the flow rate required.

6. Safety and Regulations: Compliance with local regulations and safety standards is essential. The installation should follow any specific guidelines, such as burying the pipes at the appropriate depth to protect them from freezing or damage.

7. Maintenance and Access: Consideration should be given to the accessibility of the pipes for maintenance and repairs. Having easy access points along the pipeline will allow for efficient monitoring and addressing any potential issues.

8. Budget: The farmer should determine a budget for the installation, including the cost of materials, labor, and any additional equipment required. Obtaining quotes from multiple contractors or suppliers can help in making an informed decision.

It is advisable for the farmer to consult with professionals, such as plumbers, irrigation specialists, or agricultural engineers, to ensure a well-designed and properly installed water pipe system. Their expertise will help optimize the water supply to the farmhouse, promoting efficient irrigation and reliable water access for agricultural activities.

Answer:

500π in^3

Step-by-step explanation:

The radius is half the diameter, so the radius is 5 in. Since the height is four times that, the height is 20 in.

The equation for the volume of a cylinder is:

\(V = \pi r^{2}h\)

We can plug in the radius and height:

\(V = \pi \times (5)^{2} \times 20\\V = \pi \times 25 \times 20\\V = 500\pi in^{3}\)

Kate will have to pay $56.25 out of pocket for her doctor visit.

The formula for calculating coinsurance is Coinsurance = (Cost of Service x Coinsurance Percent) / 100.If Kate has not met her deductible yet, she will need to pay the full $25 deductible plus 25% of the remaining bill.

The formula for calculating the amount Kate needs to pay is as follows:

Cost to Patient (C) = Deductible (D) + Coinsurance (C) * (Bill – Deductible)  In this case, Kate would need to pay (125 x 25) / 100 = $31.25. The extra $25 is the deductible, which is the amount she must pay before her insurance kicks in.This amount is due immediately upon the visit, regardless of whether or not she has met her deductible So in total, Kate would have to pay $25 + $31.25 = $56.25. In summary, Kate will have to pay $56.25 out of pocket for her doctor visit.

Using the percentage formula, the number of students that passed the test is 146.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.

We can use proportions to solve this problem.

Let the total number of students be "x".

Then, we know that 54 students failed the test, which means that the number of students who passed the test is -

x - 54

We also know that 54 students is 27 percentage of the total number of students, or -

54 = 0.27x

To solve for x, we can divide both sides by 0.27 -

54/0.27 = x

x = 200

Therefore, the total number of students is 200.

To find the number of students who passed the test, we can substitute this value into our equation -

x - 54 = 200 - 54 = 146

Therefore, 146 students passed the test.

The estimated actual temperature, when the temperature adjusted for wind chill is -35 degrees Fahrenheit, is approximately -6.923 degrees Fahrenheit.

To estimate the actual temperature if the temperature adjusted for wind chill is -35 degrees Fahrenheit, we can use the given formula:

V = -26 + 1.3x, where V represents the temperature adjusted for wind chill and x represents the actual temperature.

We are given that the temperature adjusted for wind chill is -35 degrees Fahrenheit.

Let's substitute this value into the formula and solve for x:

-35 = -26 + 1.3x

To isolate x, we can subtract -26 from both sides of the equation:

-35 + 26 = 1.3x

Simplifying the left side of the equation:

-9 = 1.3x

Now, divide both sides of the equation by 1.3:

-9/1.3 = x

Calculating the value:

x ≈ -6.923

5x + 3y - 3z = 14, 3x + y - z = 10

To determine the number of solutions, we can use the concept of determinant. If the determinant of the coefficient matrix is non-zero, there exists a unique solution. If the determinant is zero and there are no inconsistencies, then there are infinitely many solutions. However, if the determinant is zero and there are inconsistencies, then there is no solution.

By calculating the determinant, we find that it is non-zero, which means the system of equations has a unique solution. Therefore, the correct choice is A.

Now, let's solve for x, y, and z. By using a method such as Gaussian elimination or matrix operations, we can find the values of x, y, and z that satisfy the given system of equations. The solution will be:

x = 2

y = 1

z = 1

Divide by 5/6 on both sides.

x = 42

To check your work, take 42 and multiply it by 5/6, then subtract it by 7. You shoulc end up with 28.

42(5/6) = 35

35 - 7 = 28

Answer:

 Let the number she thought = 'x'

5/6 of the number : \(\sf \dfrac{5}{6}*x\)

\(\sf \text{take away 7 from $\sf \dfrac{5}{6}*x$} : \dfrac{5}{6}x - 7 \\\)

\(\sf \dfrac{5}{6}x-7 = 28\\\\\text{\sf Add 7 to both sides}\\\\ \dfrac{5}{6}x= 28 +7 \\\\ \dfrac{5}{6}x = 35\)

Multiply both sides by 6
