By writing both variables in the same side of the linear equation, we will get the standard form:
2y + (-1)*x = 4
How to write the linear equation in standard form?A linear equation between two variables x and y written in standard form is:
a*x + b*y = c
Where the coefficients a, b, and c, are all real numbers.
In this case, we have the linear equation:
2 + (1/2)*x = y
If we multiply both sides by 2, we get:
2*(2 + (1/2)*x) = 2*y
4 + x = 2y
Now we subtract x in both sides to get:
4 + x - x = 2y - x
4 = 2y - x
This is the linear equation in standard form:
2y + (-1)*x = 4

Subtraction:
Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

The parallel lines forms angles relationships.
Therefore,
x = 2y (alternate angles)
z = 2x + 90 (alternate angles)
Using substitution,
z = 2(2y) + 90
z = 4y + 90
x + 2x + 90 = 180 (sum of angles on a straight line)

Step-by-step explanation:
There are 240 kids in primary school 2/5 of pupils come to school by car and 15% walk. The remainder came by bus. How many came by bus?
Answer:
132
Step-by-step explanation:
240/5=48
48*2=96
240-15%=204
240-204=36
96+36=132
The number of pupils who came by bus is 108.
Total number of kids in school = 240
Fraction of pupils who came to school by car = 2/5
Number of pupils who came to school by car = [tex]\frac{2}{5}[/tex] × 240
= 96
Percentage of pupils who came to school by walk = 15 %
Number of pupils who came to school by walk = [tex]\frac{15}{100}[/tex] × 240
= 36
Number of people who came by bus
=Total number of kids in school - number of pupils who came by car - number of pupils who came by walk

Solve this equation using the "Distributive Property".
[tex] \sf 3(x - 2) = 21[/tex]
Answer:
x = 9
Step-by-step explanation:
Start by dividing both sides by the singular number, 3. We divide by 3 and not 21 because 21 is the result of the equation, not the coefficient.
[tex]\frac{3\left(x-2\right)}{3}=\frac{21}{3}[/tex]
We got 21 over 3 because you cannot divide 3 times an unknown number subtracted by 2 by 3. This is because we do not know the number. So that's where 21 comes in.
Next, simplify this equation by dividing whole numbers.
[tex]\frac{3}{3} = 1[/tex]
[tex]1\left(x-2\right) = \left(x-2\right)[/tex]
[tex]\frac{21}{3} = 7\\= x-2 = 7[/tex]
Lastly, add 2.
[tex]x - 2 + 2 = 7 + 2\\2 + 2 = 4\\7 + 2 = 9\\= x - 4 = 9\\x = 9[/tex]
Why x - 4 is 0: We assume x is always equal to 1, since 4 does not go into 1, the result would be 0. x - 0 = 0. Therefore, the problem became x = 9.

The area of a rectangle i 223. 2 m2. If the length i 16 m, what i the perimeter of the rectangle?
The perimeter of the rectangle is 59.9 m.
The area of the rectangle is = 223.2 m²
the length(L) of the rectangle is = 16 m
we know that the area of the rectangle is given by
Area = Length x Breadth
A = LB
therefore ,
LB= 223.2
16 x B = 223.2
B = 223.2/ 16
B = 13.95 m
∴ breadth or the rectangle is 13.95 meter.
Now , we know that the perimeter of the rectangle is given by ,
(P) perimeter = 2( Length + Breadth )
P = 2(L + B)
P = 2( 16 + 13.95)
P = 2( 29.95)
P = 59.9 m
So the perimeter of the rectangle is 59.9 meter.

What is cone?
A cone can be seen as a set of non-congruent circular disks that are stacked on one another such that the ratio of the radius of adjacent disks remains constant.
Cones typically have pyramidal shapes with circular cross sections. A right cone is a cone with the vertex located above the base's middle. Right circular cone is another name for it. If you know the height and radius of a cone and plug those values into a formula, you can quickly determine the volume of a cone.
The volume of a cone defines the space or the capacity of the cone. A cone is a three-dimensional geometric shape having a circular base that tapers from a flat base to a point called apex or vertex. A cone is formed by a set of line segments, half-lines or lines connecting a common point, the apex, to all the points on a base that is in a plane that does not contain the apex.

The perimeter of a rectangle i 202020 centimeter. The length i 666 centimeter. What i the area of the rectangle?
quare centimeter
The area of the rectangle is, 24 square centimeter.
What is area?
Area is a mathematical concept that expresses the size of a region on a planar or curved surface. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Let, the perimeter of the rectangle is 20 centimeter.
The length is 6 centimeter.
Suppose the width of the rectangle is y.
So,
Perimeter = 2(6) + 2(y)
20 = 12 + 2y
8 = 2y
y = 4
Hence, the width of the rectangle is 4 centimeter.
Since,
Area of rectangle = length x width
A = 6 x 4
A = 24
Therefore, the area of the rectangle is, 24 square centimeter.

Answer:1/6.4, and there are 5.4 times as many pigs as cows.
Step-by-step explanation: In this scenario there are 64 animals, 54 pigs and ten cows. So the ration is 10/64, which can be simplified if you like to 1/6.4
There are 54 pigs for every 10 cows, which is the same as 5.4/1.
For every cow there is 5.4 pigs, so however many cows there are you can take that number and multiply it by 5.4 to get the number of pigs.
Answer:
5/32
5.4
Step-by-step explanation:
54:10 is the ratio of pigs to cows.
It could be assumed that there are 54 pigs and 10 cows.
Problem is asking for the ratio of cows to all animals. So,
Add up the pigs and cows to get 64 total animals.
Input the numbers to the ratio cows:all animals
10:64
Change to a fraction
5/32
How many times the number of cows is the number of pigs. This can be found by dividing the number of pigs by the number of cows.
54 / 10 = 5.4
The number of pigs is 5.4 times more than the number of cows.

Write an equation for the trend line shown on the scatter plot.
An equation for the trend line shown on the scatter plot is y = 5x + 15.
How to find an equation for the trend line?In order to determine a linear equation for the trend line (line of best fit) that models the data points described in the scatter plot above, we would have to calculate the slope of this line.
By critically observing the scatter plot, we can reasonably and logically deduce the following points through which the trend line passes through:
Points (x, y) = (2, 25)
Points (x, y) = (6, 45)
Mathematically, the slope of any straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Slope, m = (45 - 25)/(6 - 2)
Slope, m = 20/4
Slope, m = 5.
At point (2, 25), a linear equation for the trend line can be calculated by using the point-slope form:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x represents the length of trip (in days).y represents the weight (lbs).Substituting the given parameters into the formula, we have;
y - y₁ = m(x - x₁)
y - 25 = 5(x - 2)
y - 25 = 5x - 10
y = 5x - 10 + 25
y = 5x + 15.

How to determine the equivalent of x?In this question, the mathematical statement of the equation is given as
5x to the power of 7 times s = 20x to the power of 4
When the mathematical statement is represented as an equation, we have the following representation
5x⁷ * s = 20x⁴
Divide both sides by x⁴
So, we have the following representation
5x⁷/x⁴ * s = 20x⁴/x⁴
Evaluate the quotients
This gives
5x³ * s = 20
Divide both sides by 5
x³ * s = 4
So, we have
x³ = 4/s
Take the cube root of both sides
x = ∛4/s
