By subtraction, the variable x will eliminate and we will find out the value of y in the given system of equations.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given system of equations,

2x + 7y = 32 and 2x + y = 8

Subtract both equations from each other,

(2x + 7y) - (2x + y) = 32 - 8

2x + 7y - 2x - y = 24

2x - 2x + 7y - y = 24

6y = 24

y = 4

Hence "By subtraction, the variable x will eliminate and we will find out the value of y in the given system of equations".

Step-by-step explanation:

its pretty simple

The rectangle has the consecutive integers of 21 inches and 22 inches for its width and length respectively.

Consecutive integers are numbers that follow in a particular order, usually just one after the for example, 1, 2, 3,... and so on.

Let the width of the rectangle be represented by x so that the length will be x + 1 as they consecutive integers

The perimeter of the rectangle will have the equation;

x + x + x + 1 + x + 1 = 86 inches

4x + 2 = 86 inches {collect like terms}

4x = (86 - 2) inches {subtract 2 from both sides of the equation}

4x = 84 inches

x = (84/4) inches {divide through by the coefficient of x}

x = 21 inches

Therefore, the rectangle has width of 21 inches and length of 21 + 1 = 22inches.

The total area of the space will be equal to 175 square meters.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Elizaveta painted 35 square meters of wall space. This represents 20% of the total area.

The total area will be calculated as,

20% of area = 35 square meters

100% of the area = ( 35 x 100) / 20

100% of the area = 175 square meters

The rate of change is not constant.

What is rate of change ?

A rate of change is a measurement of how one quantity alters in proportion to another. The dependent variable y must be present if independent variable x is. rate of change = y-to-x conversion of change. Change rates may be positive or negative.

We know that the rate of change in a function is given by :-

(change in dependent variable) / (change in independent variable)

Let x denotes the Number of hours and y denotes the Cost of parking .

Here , x- independent variable

y- dependent variable

Now, rate of change = ( change in y) / ( change in x)

                                  = (14-10)/(3-1) = 2

Here , the rate of change = $ 2 per hour.

Again rate of change =  ( change in y) / ( change in x)

                                    = (16-14)/(5-3) = 1

Here , the rate of change = $ 1 per hour.

Since both rate of changes are not equal , it means the rate of change is not constant.

Finding the solution to linear equations in one, two, three, or more variables is referred to as solving a linear equation. In simple words, finding the values that satisfy a Linear equation.

Here we have

Equation 3(18t +1) = 20t +3  

Let's solve the given expression to get the missing step

=> 3(18t +1) = 20t +3

Multiply (18t + 1) by 3

=> 54t + 3 = 20t + 3

Subtract 3 from both sides

=> 54t + 3 - 3 = 20t + 3 - 3

=> 54t = 20t

Subtract 20t from both sides  

=> 54t - 20t = 20t - 20t    

=>  34t = 0

Divide by 34 into both sides

The value of p, using the exterior angle property is 53°.

What is the exterior angle property of a triangle?

The exterior angle property of a triangle states that the sum of the measures of the two non-adjacent angles of a triangle is equal to the measure of the exterior angle of the triangle. This means that if a triangle has three interior angles, the measure of any non-adjacent angle of the triangle must be equal to the measure of the exterior angle of the triangle. This property is useful in solving for unknown angles when the measures of two angles are known. For example, if two angles of a triangle measure 30° and 45°, then the measure of the third angle must be 105°, which is the same measure of the exterior angle.

The Exterior angle is = Sum of the Interior opposite angles.

By using the exterior angle property, we can get the following:

p+p-13°=p+40°

=>p=40°+13°

=>p=53°

The value of p is 53°

The question is incomplete , I am answering it with my general knowledge,

Zero exponent

Simplifying an expression with a 0 as the exponent does not need consideration of the base value.

Any non-zero number multiplied by 0 has the value 1.

x0 = 1, where x = 0 and x = 1, 2, 3, and so forth.

Negative exponent

For any positive integer m and non-zero number a,

a⁻ⁿ=1/a⁻ⁿ

This rule states that if the exponent is negative, it can be made positive by writing the same number in the denominator and writing one for the numerator.

When a number is positive, the exponent shows how many times it has been multiplied by itself.

On the other hand, the negative exponent indicates how many times we must divide the base number. The negative exponent, then, tells us how many times to multiply the reciprocal of the base, to put it another way.

Therefore ,the radius of the given cylinder is 10 inches

A three-dimensional space's occupied volume is measured. It is frequently expressed as a numerical value using SI-derived units, other imperial units, or US customary units. Volume definition and length definition are connected.

Here,

The volume of the cylinder is 1570 cubic inches

Volume of the cylinder = 1570 cubic inches

Volume of cylinder = π[tex]r^{2}[/tex]h

Where r is the radius of cylinder

h is the height of cylinder

So,

Volume of the cylinder = 1570 cubic inches

=> 1570 = π[tex]r^{2}[/tex]h

=> 1570 = 3.14*[tex]r^{2}[/tex]*5

=> 1570/3.14 = [tex]r^{2}[/tex]*5

=> 500=[tex]r^{2}[/tex]  *5

=> 500/5 =[tex]r^{2}[/tex]

=>100 =[tex]r^{2}[/tex]

When boys and girls are equally likely, the likelihood that at least 50 of 125 infants born will be females is 0.40.

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y = [tex]2^x[/tex]

From the graph, we see that,

x = 0, y = -1

x = 1, y = -4

Now,

The equation in the form of y = A.[tex]2^x[/tex]  + K can be written as,

Taking (0, -1) we get,

-1 = A x 1 + K

-1 = A + K ______(1)

Now,

Taking (1, -4) we get,

-4 = A x 2 + K

-4 = 2A + K _____(2)

From (1) and (2) we get,

A = K - 1 putting in (2) we get,

-4 = 2(K - 1) + K

-4 = 2K - 2 + K

-4 = 3K - 2

3K = -4 + 2

3K = -2

K = -2/3

Now,

A = K - 1

A = -2/3 - 1

A = (-2 - 3) / 3

A = -5/3

The equation is y = (-5/3) . [tex]2^x[/tex] - (2/3)

122222 * 2222221 = 2704312822242

There must be no chance that d and e will happen. If the two occurrences cannot coexist, we can infer that they are not independent.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

P(A) = n(A)/n(S)

Where P(A) is the likelihood that an event "A" will occur and n(A) is the number of positive outcomes. The total number of occurrences in the sample space is denoted by n(S).

We must have a similar probability for both events in order for them to be independent. Because of the table, we may test for independence by knowing the likelihood that e and d will occur. When we are told that occurrences d and e are mutually exclusive, the entire table of values becomes somewhat of a red herring. The chance of d given e and the probability of d given d are both equal to zero if two events are mutually incompatible. There must be no chance that d and e will happen. If the two occurrences cannot coexist, we can infer that they are not independent. There is a chance for it.

Sales tax: 3.00

The total amount of food (before additional fees): 37. 50

So, to find the amount (in dollars) of the sales tax and tip, we must use this formula:

Amount = whole number * part percent/100

So, plugging in the numbers to the formula, it would look like this:
