An equation is a collection of variables and constants. The value of x and y for the system of the equation as -2x - 4y = -18 and x = y will be x = 3 and y = 3.
What is the equation?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.
As per the given system of equations,
-2x - 4y = -18 and x = y
Substitute, x = y
-2(y) - 4y = -18
-6y = -18
y = 3 and x = 3
Hence "The value of x and y for the system of the equation as -2x - 4y = -18 and x = y will be x = 3 and y = 3".

What is the similarity?If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
Here in the image, we have a triangle having sub-triangles. The value of x is calculated by considering two right-hand triangles.
x / ( x + 5 ) = 18 / ( 18 + 6 )
x / ( x + 5 ) = 18 / 24
24x = 18x + 90
6x = 90
x = 15
The value of y will be calculated by considering the two left-hand triangles.
12 / ( 12 + y) = 15 / 20
240 = 180 + 15y
15y = 60
y = 60 / 15
y = 4
Therefore, the value of x will be 15 and the value of y will be 4.

The total number of participants who went on the seventh-grade field trip to the Pink Palace consisted of all of the seventh-grade students and 19 adult chaperones. Two-thirds of the total participants rode a large bus, and the rest rode a smaller bus. If 104 people rode the larger bus, how many students went on the field trip? Write your answer below as a single integer.
The number of students that went on the field trip is 137.
How many students went on the field trip?Let s represent the number of seventh grade students that went on the field trip.
Total number of participants = number of students + number of teachers
a + 19
Number of participants that rode the larger bus : 2/3 x (a + 19) = 104
In order to determine the value of a, take the following steps:
Multiply both sides of the fraction by 3 / 2
a + 19 = 104 x 3 / 2
a + 19 = 156
Subtract 19 from both sides of the equation:
a = 156 - 19
a = 137

How could you check your answer afterwards?
Solving the system of equations using the algebraic method gives x = 1 or x = -4
How to solve the system of equations algebraically?Given: y = x²+x-1 and y+2x=3
In order to solve the system of equations algebraically
First, rewrite y+2x=3 to make y the subject:
y = 3-2x
Then, equate the two y of the equations and solve for x:
x²+x-1 = 3-2x
x²+x-1-3+2x = 0
x²+3x-4 = 0 (factorize)
x²+4x-1x-4 = 0
(x-1)(x+4) = 0
x-1 = 0 or x+4 = 0
x = 1 or x = -4
Therefore, the solution of the system of equations is x = 1 or x = -4

Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}y=x^2+x-1\\y+2x=3\end{cases}[/tex]
The solutions to the given system of equations are the points of intersection of the two graphs.
To solve the given system of equations algebraically, first rearrange the second equation to make y the subject:
[tex]\implies y=3-2x[/tex]
Substitute the found expression for y into the first equation:
[tex]3-2x=x^2+x-1[/tex]
Rearrange to a quadratic equation and factor:
[tex]x^2+3x-4=0[/tex]
[tex]x^2+4x-x-4=0[/tex]
[tex]x(x+4)-1(x+4)=0[/tex]
[tex](x+4)(x-1)=0[/tex]
Apply the zero-product property to solve for x:
[tex](x+4)=0\implies x=-4[/tex]
[tex](x-1)=0\implies x=1[/tex]
To find the y-values of the solutions, substitute the found x-values into the rearranged second equation:

an educational psychologist wanted to know the effects of four different methods of teaching arithmetic. using 12 classrooms, each method was used in the classes. at the end of the school year, all the pupils took the same achievement test, and the means for groups receiving different methods were compared. answer the following questions about the study. a. what was the dependent variable? b. what was the independent variable? c. what was a controlled variable? d. give an example of a parameter.
The dependent variable depends on a particular situation. The independent variable does depends on the result of an experiment. The controlled variable is a variable whose value is constant.
What is dependent variable?
The variable being measured or tested in an experiment is known as the dependent variable. The results of the participants' tests, for instance, since that is what is being measured, would be the dependent variable in a study looking at how tutoring affects test scores.
What is independent variable?
This isn't the same as an experiment's independent variable, which is a variable that can stand on its own. Tutoring would be the independent variable in the aforementioned case. The dependent variable (test results), however, may alter depending on the independent variable (tutoring).
What is controlled variable?
Anything kept constant or constrained in a research study is referred to as a control variable. Despite not being relevant to the study's objectives, this variable is controlled because it might have an impact on the results.

a plane has a cruising speed of 250 miles per hour when there is no wind. at this speed, the plane flew miles with the wind in the same amount of time it flew miles against the wind. find the speed of the wind.
The speed of the wind is 50 mph.
Define speed.Speed, expressed in terms of meters per second, is the rate at which an object's position changes. A thing moves one metre in one second, for instance, if it starts at the origin and moves three metres in three seconds. The formula for speed is as straightforward as dividing a distance by a time.
Given,
250 mph for the plane's speed when there is no wind
v is the wind speed.
Think about how the plane will move against the wind:
V' = the rate of flight of the aircraft against the wind = V + v = 250 + v
300 miles is the distance travelled in d'.
T is the passage of time over the distance.
The distance's travel time is specified as
t' = d'/V'
t' = 300/(250 + v) eq-1
Think about how the plane moves when flying against the wind:
V" is the speed of a plane travelling against the wind and equals V - v. This equals 250 - v.
D" = 200 miles of distance travelled
t" is the passage of time over the distance.
The distance's travel time is specified as
t'' = d''/V''
t'' = 200/(250 - v) eq-2
Due to this:
travelling time of 300 time required to drive 200 miles in miles
t' = t''
using eqs 1 and 2
300/(250 + v) = 200/(250 - v) (250 - v)
3/(250 + v) = 2/(250 - v) (250 - v)
750 - 3 v = 500 + 2 v
5 v = 250
v = 50 mph

The probability of selecting two students (a and b) randomly is found as 1/380.
What is referred as the word probability?The study of random experiments is what aids in determining the likelihood of an event.The study of probabilities, which are determined by the ratio of favorable cases to possible cases, is known as probability.The formula for evaluating the Probability is-
Probability = Favourable outcomes / Total outcomes.
As, per the given question.
Total number of students = 20.
The probability for selection of 'a' is 1/20.
Now, the total students left is 19.
Thus, the probability for selection of 'b' is 1/19.
The total probability for selection of both is -
Probability(a and b) = 1/20×1/19
Probability(a and b) = 1/380
