Translate this sentence into an equation: "The difference between three-fifths of a number a 7 is –36."

Answer: 6a³ + a² - 7

Step-by-step explanation:

(5a³ + 4a² − 3a + 2) + (a³ − 3a² + 3a − 9)=

5a³ + a³ + 4a² − 3a² - 3a + 3a + 2 - 9=

6a³ + a² - 0 - 7 = 6a³ + a² - 7

Answer:

6a³ + a²-7

Step-by-step explanation:

1. Get rid of the parentheses by distributing them.

(5a³ + 4a² − 3a + 2) + (a³ − 3a² + 3a − 9) = 5a³ + 4a² − 3a + 2 + a³ − 3a² + 3a − 9

2. Add like-terms.

5a³ + 4a² − 3a + 2 + a³ − 3a² + 3a − 9 = 6a³ + a²-7

Note that just like solving a linear equation, instead of having two sides, you have three. And, whatever you carry out on one side, you have to carry out on all three.

Although, unlike linear equations, if you are dividing/multiplying all sides with a negative integer, then you have to flip the signs.

The evaluation of the expression, if m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5 , and t = − 2 | 16 + 4 ( 3 q + p ) is 46.

the given expression is  t = − 2 | 16 + 4 ( 3 q + p )

Then since we are given  m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5

Then, we can substitute all the given values of the terms into the given expression as :

t = − 2 | 16 + 4 ( 3 q + p )

t= -2 I 16+4(-18+2)

t= -2 I 16+4(-16)

t= -2 I 16 -64

t= -2 I -48

t =46

a) Because it is an equilateral triangle, all the sides must have equal lengths.

The perimeter = 24cm -> Each side = 8.
Area = 1/2 b.h = 8.8.1/2 = 32 cm2.

b) A square has all of its sides of equal lengths just like an equilateral triangle.

The perimeter = 24cm -> Each side = 6.
Area = side.side = 6.6 = 36 cm2.

c) Since they have equal perimeters and the same properties (all sides equal) BUT they have different number of sides and lengths, they won't have the same areas.

d) A rectangle. E.g :
A set of lengths of 5cm and 7cm makes a rectangle with a perimeter of 24cm : (5+7).2

But, its area equals 5 x 7 = 35cm2, which is greater than the triangle.

Answer:

a) 27.71 cm²

b) 36 cm²

Step-by-step explanation:

a) Perimeter of equilateral triangle = 3a

Here, a is the side of equilateral triangle.

Perimeter of equilateral triangle = 24 cm

                   3a = 24 cm

                    a = 24 ÷ 3

                    a = 8 cm

[tex]\sf Area \ of \ equilateral \ traingle = \dfrac{\sqrt{3}}{4}a^2[/tex]

                                         [tex]\sf = \dfrac{\sqrt{3}}{4}*8*8\\\\ = 1.732*2*8\\\\ = 27.71 \ cm^2[/tex]

b)   Perimeter of square = 4s

Here, s is the side of square.

Perimeter of square = 24 cm

                         4s = 24

                           s = 24 ÷ 4

                           s = 6 cm

Area of square = s*s

                         = 6 * 6

                         = 36 cm²

c)  When the dimensions (length, width, height) of the shape changes, the area and volume changes.

d) Length of the rectangle is 10 cm and width is 2 cm.

Perimeter of rectangle = 2*length + 2* width

                                      = 2*10 + 2*2

                                       = 20 + 4

                                       = 24 cm

Area of perimeter of rectangle = length *width

                                                   = 10 * 2

                                                   = 20 cm²

1. The slope of the line on the graph is: 6

2. The graph of the line with a slope of 4/3 is shown in the image below.

Slope of a line = change in y / change in x = rise/run.

The equation that can be used to represent a linear graph can be written in slope-intercept form as y = mx + b, where the value of b is the y-intercept of the line and the value of m is the slope of the line.

1. Using two points on the line, (0, -1) and (1, 5):

Slope of the line = change in y / change in x = (-1 - 5)/(0 - 1)

Slope of the line = -6/-1

Slope of the line = 6

2. Slope (m) = 4/3

A point on the line is given as (1, 3)

Write the equation of the line by substituting (a, b) = (1, 3) and m = 4/3 into y - b = m(x - a):

y - 3 = 4/3(x - 1)

y - 3 = 4/3x - 4/3

y = 4/3x - 4/3 + 3

y = 4/3x + 5/3

The graph of y = 4/3x + 5/3 is shown in the image below.

The required equation of slope intercept the line parallel to the given line and passing through (4,5) is  y = -1/4x + 6.

What exactly does slope intercept mean?

1)   5x + y = 3

   y = - 5x + 3

compare equation y = mx + c

        m = -5  

2) 7x - 5y = 20

      5y = 7x - 20

   y = 7/5x - 4

compare equation y = mx + c

      m = 7/5

3) y = -1/3x - 4

 compare equation y = mx + c

         m = -1/3

4) points ( 4,5) parallel to y = 1/4x - 4

               m₁  = m₂

  compare equation y = mx + c

             m₁ = 1/4  c = -4

now lets put the value

                  1/4 = m₂

So the equation of the line parallel to the given line assuming that its y-intercept is b will be

 y = 1/4x + b

the equation of the parallel line which passes through

(4,5, it should satisfy these points.

So let's substitute these points

5 = -4/4 + b

5 = -1 + b

b =  6

Hence the required equation of the line parallel to the given line and passing through (4,5) is

            y = -1/4x + 6

Note that the rational numbers represented on points- P, Q, R, and S are given as follows:  7/3, 8/3, -4/3, -5/3 respectively. See the explanation below.

A rational number is defined in mathematics as the proportion or fraction p/q of two integers, a numerator p, and a non-zero denominator q. 3/7, for example, is a rational number, as is every integer.

For the solution above:
Each section in between two numbers is broken into three sections.

Thus, we have a = (6/3), P = (7/3), Q = (8/3) and B = (9/3)

In the same way,

T = = -3/3,

R = -4/3

The arity typically assumed to be limited. The "typical" operations of finite dimensionality are referred to as the finiteary operations when infinitary operations are taken into consideration. The mean of the five numbers is 8.2, four of numbers are 8, 10, 12 and 10. The fifth number is 1.025.

An operation, often known as a "operand" or "argument," is the function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by number of operands.

Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are operations that are most frequently studied. A constant is operation with arity zero, often known as a nullary operation. An example of operation of arity 3, sometimes known as a ternary operation, is the mixed product.

the values of both angles are

2x - 8 = 2*25 - 8

          = 42 degree

x -7 = 25 - 7

      = 18 degree

Both internal and external angles make up a triangle. The angle that forms between two of a triangle's adjacent sides is known as the interior angle. The angle created between a triangle's side and its next-to-furthest side extending outward is known as the exterior angle. Triangle Angle sum feature of triangle states for ABC that 180 degrees is the sum of the triangle's internal angles.

2x - 8 + x - 7 + 90 = 180
