The value of the equation A = ( 8 . 4 ) + ( 2 . 4 ) + 2 = 42

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 8 + 2 ) . 4 + 2   be equation (1)

On simplifying the equation , we get

A = ( 10 ) 4 + 2

A = 40 + 2

A = 42

Substitute the value of A as

A = ( 8 . 4 ) + ( 2 . 4 ) + 2

On simplifying the equation , we get

A = 32 + 8 + 2

A = 40 + 2

A = 42

Hence , the equation is A = ( 8 . 4 ) + ( 2 . 4 ) + 2

Answer:

1q1231564rr54drdfgy6

Answer:

D

Step-by-step explanation:

-1.25 is less than -1.02 and 1.4.

> -1.25 + 1.02 = -0.23

1.4 is a greater amount because it is a positive number

So, if you put it this way, -1.25 is lesser, -1.02 is the 2nd least, & 1.4 is the greatest.

Which means your overall answer should be -1.25 < -1.02 < 1.4

Step-by-step explanation:

let v is the speed of the wind,

the equation of the speed:

(550 + v ) × 5 = (550 - v) × 6

2750 +5v = 3300 - 6v

11v = 3300 - 2750

11v = 550

v = 550/11

v = 50

therefore, the speed of the wind =

50 mph

Step-by-step explanation:

5(550 + v) = 6(550 - v)

2.750 + 5v = 3.330 - 6v

5v + 6v = 3.300 - 2.750

11v = 550

v = 550 ÷ 11

v = 50mph

Answer:

Let's solve your system by elimination.

2a + 3c =66 ; 3a + 5c = 105

Multiply the first equation by 5,and multiply the second equation by -3.

5 (2a + 3c = 66)

−3 (3a + 5c = 105)

Becomes:

10a + 15c = 330

−9a − 15c = −315

Add these equations to eliminate c:

a = 15

Now that we've found a let's plug it back in to solve for c.

Write down an original equation:

2a + 3c = 66

Substitute 15 for a in 2a + 3c = 66:

(2)(15) + 3c = 66

3c + 30 = 66 (Simplify both sides of the equation)

3c + 30 −30 = 66 −30 (Add -30 to both sides)

3c = 36

3c3= 363 (Divide both sides by 3)

c = 12

Answer:

a = 15 and c = 12

Answer:

[tex]n^2 -3n - 6[/tex]

Step-by-step explanation:

Looking at the image attached, you must first work out the difference between each term. This is +0, +2, +4, +6, +8, +10 (shown in orange).

Because you now have a linear sequence, the difference is now the same each time. This is +2 (shown in blue).

Because the original sequence is a quadratic, you have to halve the second difference (the +2). This means that the value of [tex]n^2[/tex] is 1, so 1[tex]n^2[/tex] or just [tex]n^2[/tex] .

If you write out the values of [tex]n^2[/tex], you can work out how much more you need to add or take away. For example, take the first three terms in the sequence.

n = 1, 2, 3

x = -8, -8, -6

[tex]n^2[/tex] = 1, 4, 9

Work out the difference between [tex]n^2[/tex] and x:

1 - -8 = 9

4 - -8 = 12

9 - -6 = 15

This gives you yet another linear sequence, 9, 12, 15.

Working out the formula for this, the difference is 3 each time, so it is 3n. The first value of n is 1, so 3n is 1. The difference is 6, so the formula for this linear sequence is 3n + 6.

Because [tex]n^2[/tex] is greater than x, you need to take 3n + 6 away from [tex]n^2[/tex].

This gives [tex]n^2[/tex] - (3n+6), so the final answer is:

[tex]n^2[/tex] - 3n - 6.

The cubic function is used to represent the length, width or height of a box. The correct option is C.

The cubic function is defined as a function having a degree of three. It is the same as that of cubic polynomials.

A cubic function is defined in mathematics as a function of form f(x)=ax³+bx²+cx+d, where the coefficients a, b, c, and d are complex numbers and the variable x takes real values.

The box has three dimensions that are length, width, and height. The volume of the box will be calculated by the product of the three sides of the box.

There are three dimensions involved in the calculation of the volume of the box. It means that the volume will be a cubic function.

Step-by-step explanation:

Step-by-step explanation:

the numbers : x, y

x = 5 + 3y

x + y = 33

when using the first equation in the second we get the mentioned equation (it does not matter which of the 2 numbers is x and which is y, it can all be vice versa, as you can see) :

5 + 3y + y = 33

5 + 4y = 33

4y = 28

y = 7

so, when you try the numbers above in the unsimplified equation, you will also find that 7 is the right answer.

the other number is based on my equations (with the reversed names) :

x = 5 + 3y = 5 + 3×7 = 5 + 21 = 26

the smaller number is 7.

the larger number is 26.
