Without solving state the property or properties that justify why the two equations must have the same solution set.
5(v - 4) = 100 and (v - 4)5 =100

Answer:

x = -16

Step-by-step explanation:

An exterior angle of a triangle is the angle formed when one side is extended.

The sum of all exterior angles is 360°

Since the 3 exterior angles are given in terms of x we can add them up, set the sum to 360 and solve for x

Adding we get

-9x + 13  
-2x +  3    
-10x +  8
_________

-21x + 24
_________

∴ -21x + 24 = 360

Subtract 24 from both sides:
-21x = 360-24
-21x = 336

Divide both sides by -21
-21x/-21 = 336/-21
x = -16

The two numbers with the value of 9 in the first digit being 10 times the value of 9 in the second digit are 98 and 9.

The first number will be 9 and the second number will be 98.

In the second number, the 9 is in the tens position which means that it has the value of 90.

In the first number, the value of 9 is simply 9.

therefore,90 is 10 times the value of 9 which means that 9 and 98 satisfy the requirements.

The “tens” digit is the digit in the second place to the left of the decimal point. The tens digit of 42936.875 is “3”. The “tenths” digit is the digit directly to the right of the decimal point.Each digit is a different place value. The left digit is the tens' place. It tells you that there are 8 tens. The last or right digit is the ones' place which is 4 in this example

In our decimal number system, the value of a digit depends on its place, or position, in the number. Each place has a value of 10 times the place to its right. A number in standard form is separated into groups of three digits using commas.

The dimensions of the another rectangle is 2 cm and 4 cm.

According to the statement

We have to find that the perimeter of another rectangle.

So, For this purpose, we know that the

The perimeter of a shape is defined as the total length of its boundary.

From the given information:

The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. draw another scale drawing of the pool using the scale 25 m to 2 cm.

Then

From the given rectangle,

Length of the rectangle = 5 cm

Width of the rectangle = 10 cm

Ratio of length : width = 1 : 2

Perimeter of the rectangle = 2(l + b)= 150 cm

l + b = 75 -----(1)

Since, l : b = 1 : 2

l/b = 1/2

b = 2l ------(2)

From equations (1) and (2),

l + 2l = 75

3l = 75

l = 25 m

Width 'b' = 2(25) = 50 m

Now we've to draw a rectangle with a scale = 25 : 2

Therefore, multiplier factor = 25/l = 25/2

l = 2 cm

Similarly,

50/w = 25/2

w = 4 cm

Now we are able to draw a rectangle with length = 2 cm and width = 4 cm.

So, The dimensions of the another rectangle is 2 cm and 4 cm.

Answer: 16

Step-by-step explanation:

Let Skylar is x year old

Hence, they ages is (x+1), (x+2), (x+3)

Thus,

x+(x+1)+(x+2)+(x+3)=70

x+x+1+x+2+x+3=70

4x+6=70

4x+6-6=70-6

4x=64

Divide both parts of the equation by 4:

x=16

The age of Skylar is 16.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific values in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the ages of the siblings be x, x+1, x+2 and x+3.

and, the sum of the ages be 70.

So, x+ x+1 + x + 2 +x+ 3 = 70

4x + 6 = 70

4x = 70 - 6

4x = 64

x= 64/4

x = 16.

Then, the age of siblings be 16. 17, 18 and 19.

A mean or average is the ratio of the sum of observations to the number of observations.

For the first case:

Mean = (13*5 + 14*10 + 15*19 + 16*13 + 17*4)/75 = 10.21

For the second case:

Mean =(3*2 + 4*10 + 5*21 + 6*11 + 7*5 + 8*3)/33 = 10.48

According to the equation does the graph of the systems of equations solve is B.

1/3x+1=2x-4 is correct.

A graph is a structure consisting of a group of items, some of which are "linked." The objects are mathematical abstractions known as vertices, and each pair of connected vertices is known as an edge.

It is evident from the graph that the two lines intersect at the location:

(3, 2).

To put it another way,

at x =3, y = 2

The point where two lines intersect is:

(x, y) = (3, 2) (3, 2).

Now,

x = 3 is the point  of the x-coordinate

y = 2 is the point of the y-coordinate

Now, examine the equation, 1/3x+1=2x-4, to see if it contains the correct x-coordinate value.

(1/3)x + 1 = 2x -4

subtracting 1 from both side:

(1/3)x + 1 -1  = 2x -4 -1

We get:

(1/3)x = 2x -5

subtract 2x from both sides:

(1/3)x -2x = 2x -5 -2x

We get:

-(5/3)x = -5

on simplifying the equation we get:

x = 3

the value of x = 3

this show that the 1/3x+1=2x-4 is correct.

The x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2

The x-intercept of the function is the point or points where the graph of the function crosses the x-axis i.e. the point where the function equals 0

The function is given as

f(x) = cos(x)

And the interval is given as

[0, 2)

The above means that we determine the value of x when the function f(x) equals 0

So, we have

cos(x) = 0

The above equation can be solved graphically

See attachment for the graph of the function f(x) = cos(x)

In the interval [0, 2), the graph crosses the x-axis at points x = π/2 and 3π/2

Hence, the x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2

f(x) = x³, g(x) = (x + 3)³ - 4 = f(x + 3) - 4

The required line representing the rise and the run of the line is created.

And the slope of the line in its simplest form is 9/-18.

Given a line is represented on the graph.

we need to create lines representing the rise and run of the line.

To find the slope of the line we need to determine the rise and run of the line.

The slope of a line is defined as the rise divided by the run, or the ratio of the rise to the run. It gives information about a line's slope in the coordinate plane. Finding the slope between two separate places is comparable to calculating the slope of a line.

The coordinates of the points are:

(9,0) = (x₁ , y₁)

(₋9 , 9) = (x₂ , y₂)

we know that slope (m) = rise/ run

rise  = y₂ ₋ y₁

= 9 ₋ 0

= 9

run = x₂ ₋ x₁

= ₋9 ₋ 9

= ₋18

hence the slope is 9/₋18

The required slope of the line is 9/-18.
