Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be represented as A

Now , the value of A is

-2x + 3y = 15   be equation (1)

Let the first equation be represented as B

Now , the value of B is

x + y = 10   be equation (2)

On simplifying the equation , we get

Subtracting y on both sides of the equation , we get

x = 10 - y   be equation (3)

Substituting the value of x from equation (3) in equation (2) , we get

-2 ( 10 - y ) + 3y = 15

On simplifying the equation , we get

The final price is 97.714% of the original price. To the nearest whole number, that's 98%.

Let's call the final price of the bed "x".

       $350 * 0.15 = $52.50$ discount

       $297.50 * 0.15 = $44.63 markup

       $342.13 / $350 = 0.97714

So, the final price is 97.714% of the original price.

To the nearest whole number, that's 98%.

The method used to solve this problem is applicable to a wide range of similar problems in pricing and discounting, as well as in finance and economics. This method can be used to calculate the final price of an item after applying a discount followed by a markup, or to find the original price of an item given the final price and the discount and markup amounts.

The volume of the solid right pyramid is given as V=  1/3(b*h) and hence volume(V) is equals to h/3(5.2) cm^3 or 1.73h cm^3

In solid right pyramid volume is given by the product of base of the area and the height of the solid pyramid  and it is divided by 3 and volume is defined as the 3-dimensional  area covered by the solid right pyramid . so volume is the product of the base of the area and the height and it is divided by 3

So , here "b" is the base of the area

"h" is the height of the solid right pyramid

We have ,base B=5.2 cm^2

height H= h cm

As , Volume is given by the product of the base and height of the right pyramid and it is divided by 3 , we used to solve the volume as

2. Split the middle coefficient into two factors that add to the middle coefficient and multiply to the last coefficient.

1. First, identify the GCF of the coefficients, which is 1. Since there is no GCF, this step can be skipped.

2. Next, split the middle coefficient (17) into two factors that add to the middle coefficient and multiply to the last coefficient.

Since 17 = 8 + 9, we can use 8 and 9 as our two factors.

3. Group the terms by the common factors.

We can group the first and last term together (6x2 + 5) and the middle term separately (17x).

4. Factor out the common factor, which is x, from the first and last group. This gives us x(6x + 5).

5. Lastly, factor the remaining quadratic expression (6x + 5).

Since 8 and 9 are the two numbers that add to the middle coefficient and multiply to the last coefficient, we can use them as our two factors. This gives us (6x + 8)(x + 9).

There were 128 children and 155 adults.

Let us first set up our system by assigning x and y to mean something. Let x = the number of children and y = the number of adults.

First equation: Children cost $1.50 and Adults cost $4.00. In order to find the amount of money a group of children will cost, we multiply the number of children, x, by 1.5.

This is represented by 1.5x. For adults, who cost 4 dollars to enter, we will use 4y. The total amount of money made on the given day was $632. To get this amount, we must add 1.5x and 4y.

1.5x+4y=632 --------(1)

Second equation: Total amount of people on the given day is 238. To get this number, we must add together x and y, or the number of children and adults.

x + y = 238-----(2)

System of equations:

1.5x+4y=632

x+y = 238

Let's use the substitution of the x variable to solve the system.

x+y=238.

y=238-x

Substitute y = 238 - x into the first equation.

1.5x + 4 (238 - x) =632

1.5x + 952 - 4x = 632  

952- 2.5x = 632

-2.5x = -320

x = 128

Substitute x =128 back into y = 238 - x

They need to ride "x = 20 - (hours a first day + hours second day)" on the third day to make their goal of biking a total of 20 hours in the park.

Let's call the number of hours Rebecca and Dan rode on the third day "x".

Then, the total number of hours they rode in the park is given by:

total hours = hours first day + hours second day + x

And, we know that their goal is to bike a total of 20 hours in the park, so we can set the equation equal to 20:

total hours = hours first day + hours second day + x = 20

We can substitute in the values for hours first day and hours second day:

20 = hours first day + hours second day + x

So, to find the number of hours they need to ride on the third day to reach their goal, we just need to solve for x:

x = 20 - (hours first day + hours second day)

We would need to know the values for hours first day and hours second day to find the exact value of x.

For Jennifer:

t + 2j = 94

We can use these two equations to solve for t and j. Subtracting the second equation from the first, we have:

3t + j = 87

Next, we can substitute the second equation into the third equation to eliminate t:

3(t + 2j) = 3 * 94 = 282

Expanding the left side, we have:

3t + 6j = 282

Subtracting j from both sides:

3t + 5j = 282 - j

Combining like terms:

The value of (16^x)/(2^y) if 4x-y=12 is 4096.

Therefore the answer is 4096.

We are given the equation 4x - y = 12. To find the value of (16^x)/(2^y), we need to find the values of x and y. To do this, we can isolate either x or y and solve for it:

4x - y = 12

y = 4x - 12

We can substitute the expression for y into the expression for (16^x)/(2^y) to find the value:

(16^x)/(2^y) = (16^x)/(2^(4x - 12)) = (16^x)/(2^(4x)) * (2^12)

Note that 2^4 = 16, so (16^x)/(2^4x) = 1, which means that (16^x)/(2^y) =2^12.

H(u) = u arctan(x) - (1) arctan(t) dt is obtained by integrating u arctan(t) with respect to t from 1 to x.

The original function h(x) = 1/x arctan(t) dt can be rewritten as h(u) = u arctan(t) dt by substituting u = 1/x. This is accomplished by substituting 1/u for each instance of x in the original equation.

The result of integrating this equation from 1 to x with regard to t is h(u) = u arctan(x) - (1) arctan(t) dt. The integral of u arctan(t) from 1 to x less the integral of arctan(t) from 1 to x can be used to represent this. The integration variable for the first integral is u, while the variable for the second integral is t.

the function is defined on the interval [0,1], we must have 0 ≤ x ≤ 1. Therefore, the value of x for which[tex]f'(x)=0 is x = 0.[/tex]

To find the value of x for which[tex]f'(x)=0[/tex], we need to differentiate the given function.

[tex]f'(x) = (e-1)(π/2)(ex)(cos(π/2x)) - (sin(π/2x))[/tex]

Now, set [tex]f'(x) = 0[/tex]and solve for x.

[tex](e-1)(π/2)(ex)(cos(π/2x)) - (sin(π/2x)) = 0(e-1)(π/2)(ex) = (sin(π/2x))ex = (sin(π/2x))/(e-1)(π/2)[/tex]

Taking natural log on both sides

[tex]xln(e) = ln(sin(π/2x)) - ln((e-1)(π/2))xln(e) = ln(sin(π/2x)) - ln(e-1) - ln(π/2)x = (ln(sin(π/2x)) - ln(e-1) - ln(π/2))/ln(e)[/tex]

Since the function is defined on the interval [0,1], we must have 0 ≤ x ≤ 1.

Therefore, the value of x for which [tex]f'(x)=0 is x = 0.[/tex]
