Final answer:

The simplified form of the expression (x-y)/(x+y) - (x+y)/(x-y) is -4xy / (x²-y²).

Explanation:

To simplify the expression (x-y)/(x+y) - (x+y)/(x-y), we need to find a common denominator and then combine the terms.

The common denominator for the fractions is (x+y)(x-y), which is the product of both denominators and simplifies to x²-y² due to the difference of squares.

Let's go ahead and combine the fractions over this common denominator:
 ((x-y)² - (x+y)²) / (x²-y²)

Expanding the numerators gives:
 (x² - 2xy + y²) - (x² + 2xy - y²) / (x²-y²)

Now, simplify by combining like terms:
 (x² - x² - 2xy - 2xy + y² - y²) / (x²-y²)

Cancelling out the x² and y² terms, we are left with:
 -4xy / (x²-y²)

Thus, the simplified form of the given expression is:
 -4xy / (x²-y²)

Answer: Yes

Step-by-step explanation: 7x and 9x are called terms and the numbers in front of the variables, +7 and +9 are called coefficients.

Because the variables, x and x are identical, the two terms in this problem are called like terms so yes, 7x and 9x are like terms.

208.81 square centimeters of aluminium are needed

Solution:

Given that,

Radius = 3.5 cm

Height = 6 cm

We have to find the square centimeters of aluminum needed

So we have to find the surface area of cylinder

The surface area of cylinder is given by formula:

[tex]A = 2 \pi r(h+r)[/tex]

Where "r" is the radius and "h" is the height of cylinder

Substituting the values we get,

[tex]A = 2 \times 3.14 \times 3.5 \times (6+3.5)\\\\A = 21.98 \times 9.5\\\\A = 208.81[/tex]

Thus 208.81 square centimeters of aluminium are needed

The soda can requires approximately 208.51 square centimeters of aluminum.

To determine the amount of aluminum needed to make the soda can, we need to calculate the surface area of the cylinder. The formula for the surface area of a cylinder is:

Surface Area = 2πr(h + r)

Given the radius (r) = 3.5 cm and the height (h) = 6 cm, we substitute these values into the formula:

Surface Area = 2 * 3.14 * 3.5 * (6 + 3.5)

First, calculate the term inside the parentheses:

6 + 3.5 = 9.5

Next, multiply by the radius:

3.5 * 9.5 = 33.25

Finally, multiply by 2π:

2 * 3.14 * 33.25 ≈ 208.51

So, the total surface area of the soda can is approximately 208.51 square centimeters of aluminum.

Answer:

Step-by-step explanation:

y= 16

x=15

Using the substitution method,

The value of x is -1 and y is 3.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 8 is an equation.

We have,

2x + 6y = 16 _____(1)

3x - 5y = -18 ______(2)

From (1) we get,

2x = 16 - 6y

x = (16 - 6y)/2

Substituting in (2).

3x - 5y = -18

3 x (16 - 6y)/2 ) - 5y = -18

3 x (8 - 3y) - 5y = -18

24 - 9y - 5y = -18

24 + 18 = 9y + 5y

42 = 14y

y = 42/14

y = 3

And,

x = (16 - 6y)/2

x = (16 - 6 x 3) / 2

x = (16 - 18) / 2

x = -2/2

x = -1

Thus,

x = -1 and y = 3.

Final answer:

To solve the system of equations x + 14y = 38 and x + 2y = 5, we used the elimination method to find x = -0.5 and y = 2.75.

Explanation:

Solving the System of Equations

The question requires solving a system of linear equations. The given equations are:

x + 14y = 38 (Equation 1)

x + 2y = 5 (Equation 2)

We can solve this system using the substitution method or elimination method. Let's use the elimination method:

Multiply Equation 2 by 7 to make the coefficient of x the same in both equations:

7x + 14y = 35 (Equation 3)

Subtract Equation 3 from Equation 1 to eliminate x:

(x + 14y) - (7x + 14y) = 38 - 35

-6x = 3

x = -0.5

Substitute x = -0.5 in Equation 2 to find y:

-0.5 + 2y = 5

2y = 5.5

y = 2.75

The solution to the system of equations is x = -0.5 and y = 2.75.

Answer:

The volume of the  cylinder is

 [tex]V=99\ in^3[/tex]

Step-by-step explanation:

we know that

The volume of the cone is equal to

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

[tex]V=33\ in^3[/tex]

so

[tex]33=\frac{1}{3}\pi r^{2}h[/tex]

Multiply by 3 both sides

[tex]99=\pi r^{2}h[/tex] ----> equation A

Remember that

The volume of a cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

The cylinder has the same height and the same  radius as the cone

so

Equate the volume of cylinder to equation A

[tex]V=99\ in^3[/tex]

The volume of the cylinder is 99 cubic inches and this can be determined by using the formula of the volume of the cylinder and the volume of the cone.

Given :

The formula of the volume of a cone is given by:

[tex]\rm V = \dfrac{1}{3}\pi r^2h[/tex]

[tex]\rm 3V = \pi r^2h[/tex]   --- (1)

The formula of the volume of the cylinder is given by:

[tex]\rm V' = \pi (r')^2 h'[/tex]  --- (2)

According to the given data, the cylinder has the same height and the same  radius as the cone. That is:

h' = h

r' = r

So, from equations (1) and (2):

V' = 3V

According to the given data, V = 33 cubic inches.

V' = 3(33)

V' = 99 cubic inches

So, the volume of the cylinder is 99 cubic inches.

A prism with a triangular base has a volume of 432 cubic feet.

The height of the prism is 8.

The triangle base has a base of 12 feet.

Question asked:

The height of the triangular base of the prism = ?

solution:

Volume of  triangular prism = [tex]Area of triangle \times height[/tex]

[tex]432 = Area of triangle \times8[/tex]

Dividing both side by 8

[tex]54 = Area of triangle[/tex]

[tex]54 =[/tex]  [tex]\frac{1}{2} \times base \times height[/tex]

[tex]54 = \frac{1}{2} \times12\times height\\54 = \frac{12}{2} \times height[/tex]

Multiplying both side by 2

[tex]108 = 12 \times height[/tex]

Answer:

each box contained 18

Step-by-step explanation:

because 108 divided by the total number of boxes = 18

Final answer:

To determine how many cupcakes were in each of the 6 boxes for John's party with a total of 108 cupcakes, simply divide 108 by 6, resulting in 18 cupcakes per box.

Explanation:

The question asks us to determine how many cupcakes each box contained if there were a total of 108 cupcakes for John's birthday party, and 6 similar boxes were ordered in total. To find the answer, we divide the total number of cupcakes by the total number of boxes.

First, we know that the mother ordered 4 boxes initially and then ordered 2 more boxes, which gives us a total of 4 + 2 = 6 boxes. Then, we are given the total number of cupcakes, which is 108. To find out how many cupcakes each box contained, we divide the total number of cupcakes by the number of boxes:

108 cupcakes ÷ 6 boxes = 18 cupcakes per box

Therefore, each box contained 18 cupcakes.

Final answer:

The largest possible value for y + z, with y < 80 and z ≤ 70, is 149, achieved by taking the maximum whole numbers within those limits: y = 79 and z = 70.

Explanation:

To find the largest possible value of y + z given that y is a whole number less than 80 and z is a whole number less than or equal to 70, we must choose the largest whole numbers that fit these conditions. For y, the largest whole number less than 80 is 79, and for z, the largest whole number less than or equal to 70 is 70 itself. Therefore, the largest possible value for y + z is 79 + 70.

The calculation is straightforward:

79 (maximum y) + 70 (maximum z) = 149

This is the largest sum of y + z based on the given conditions.

Answer:

William will make 12 bags of food and each of the bag will contains 2 cans of fruit and 5 cans of vegetables.

Step-by-step explanation:

Given:

Number of fruits cans = 24

Number of veggies cans = 60

William will have to distribute them in equal bags with equal cans of fruits and vegetables respectively.

For this:

We have to find the GCF (greatest common factor) of 24 and 60.

GCF by listing out the factors method.

Factors of 24  : [tex]1,2,3,4,6,8,12,24[/tex]

Factors of 60 : [tex]1,2,3,4,5,6,10,12,15,20,30,60[/tex]

So,

The greatest common factor of [tex]24[/tex] and [tex]60[/tex] is [tex]12[/tex].

The number of bags William will used for equal distribution = [tex]12[/tex]

Now,

We have to distribute the veggies and fruits in equal number of cans to these [tex]12[/tex]bags.

Number of fruits cans used in each bag = [tex]\frac{24}{12} = 2[/tex]

Number of vegetables can used in each bag = [tex]\frac{60}{12} =5[/tex]

We can say that:

William will make 12 bags of food and each of the bag will contains 2 cans of fruit and 5 cans of vegetables.

Final answer:

By computing the greatest common divisor (GCD) of 24 and 60, it is determined that William can create 12 equal bags with each bag having 2 cans of fruit and 5 cans of vegetables.

Explanation:

The student is asking how to divide 24 cans of fruit and 60 cans of vegetables into bags such that each bag contains the same number of cans without any leftovers. This requires finding the greatest common divisor (GCD) of 24 and 60, which is 12. Therefore, William can make 12 bags, with each bag containing 2 cans of fruit and 5 cans of vegetables.
