Answer:

7

Step-by-step explanation:

9x + 1 = 7x - 9 + 5x - 11

9x + 1 = 12x - 20

9x + 1 - 1 = 12x - 20 - 1

9x = 12x - 21

9x - 12x = 12x - 12x -21

-3x = -21

-3x/3 = -21/-3

x = 7

Answer:

18

Step-by-step explanation:

The number of books with Clara is given by the equation C = 18 books

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the number of books with Clara be represented as C

Let the number of books with Mai be represented as M

And , Clara has 8 fewer books than Mai

So , the equation is

C = M - 8   be equation (1)

The number of books with Mai , M = 26 books

Now , when M = 26 books

On simplifying , we get

C = 26 - 8

C = 18 books

Therefore , the value of C is 18 books

Hence , the number of books with Clara is 18 books

Step-by-step explanation:

i did it

The solution is: A.an article discussing mineral resources written by the United States Geological Survey, sources are reliable.

The correct answer will be options-A and C.

Research is a process of systematic inquiry that entails collection of data; documentation of critical information; and analysis and interpretation of that data/information, in accordance with suitable methodologies set by specific professional fields and academic disciplines.

Explanation:

The research on any question starts with a "review of literature study" which helps gain the knowledge related to the aspect of the hypothesis one is studying.

The sources reviewed by the researcher must follow certain criteria to be cited like:

1. The research should be done by any governmental organisation, research institutes and affiliated universities.

2. The research paper should posses results checked and verified by the peer fellows like by the peer-review of journals.

3. The research should not be edited any general magazines, advertisements and any other unauthorized organizations.

Thus, option-A and C are the correct answer.

Answer:

The area of the triangle is 5.875 square units.

Step-by-step explanation:

First, we need to calculate the lengths of the triangle by means of Pythagorean Theorem:

[tex]a = \|\overrightarrow {QR}\| = \sqrt{(5-4)^{2}+(7-4)^{2}+(-2+1)^{2}}[/tex]

[tex]a \approx 3.317[/tex]

[tex]b = \|\overrightarrow {RS}\| = \sqrt{(3-5)^{2}+(2-7)^{2}+(-4+2)^{2}}[/tex]

[tex]b \approx 5.745[/tex]

[tex]c = \|\overrightarrow {QS}\| = \sqrt{(3-4)^{2}+(2-4)^{2}+(-4+1)^{2}}[/tex]

[tex]c \approx 3.742[/tex]

Now, we can use the following formula to fid the area of the triangle ([tex]A[/tex]), measured in square units:

[tex]A = \sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}[/tex]

Where:

[tex]s[/tex] - Semiperimeter of the triangle, dimensionless.

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Sides of the triangle, dimensionless.

The semiperimeter can be determined by this:

[tex]s = \frac{a+b+c}{2}[/tex]

If we know that [tex]a \approx 3.317[/tex], [tex]b \approx 5.745[/tex] and [tex]c \approx 3.742[/tex], the area of the triangle is:

[tex]s = \frac{3.317+5.745+3.742}{2}[/tex]

[tex]s = 6.402[/tex]

[tex]A = \sqrt{(6.402)\cdot (6.402-3.317)\cdot (6.402-5.745)\cdot (6.402-3.742)}[/tex]

[tex]A \approx 5.875[/tex]

The area of the triangle is 5.875 square units.

Answer:

Es posible diseñar 936 banderas.

Step-by-step explanation:

Para poder determinar la cantidad de banderas que es posible diseñar utilizando 1 animal, 1 color de fondo y 1 palabra representativa de un total de 8 colores, 13 animales y 9 palabras, se debe multiplicar la cantidad total de variables, y su resultado será la cantidad de banderas que se podrán diseñar.

Así, deben multiplicarse 8 x 13 x 9, es decir, el total de colores, animales y palabras. Esta multiplicación da como resultado 936, con lo cual es posible diseñar 936 banderas diferentes.

(f+g)(x)=f(x)+g(x)=(2x-6)+(4x+7)=6x+1

(f-g)(x)=f(x)-g(x)=(2x-6)-(4x+7)=-2x-13

(fg)(x)=f(x)×g(x)=(2x-6)(4x+7)=8x^2-10x-42

(f+g)(-2)=f(-2)+g(-2)=(2(-2)-6)+(4(-2)+7)=-11

Answer:

1. Dave worked for 34 hours.

2. Perimeter of the rectangle is 172 cm.

Step-by-step explanation:

1. Determination of the hours Dave worked.

Let D represent Dave.

Let M represent Mike.

Let J represent John.

Tota time worked by Dave, Mike and John is 56 hours. This can be written as:

D + M + J = 56 ..... (1)

Dave worked 6 more than 4 times as many hours as Mike. This can written as:

D = 6 + 4M .....(2)

John worked 6 less than 3 times as many hours as Mike. This can be written as:

J = 3M – 6 ........ (3)

Substituting the value of F and J into equation 1, we have:

D + M + J = 56

D = 6 + 4M

J = 3M – 6

6 + 4M + M + 3M – 6 = 56

6 – 6 + 4M + M + 3M = 56

8M = 56

Divide both side by 8

M = 56/8

M = 7

Substitute the value of M into equation (2) to obtain the value of D.

D = 6 + 4M

M = 7

D = 6 + 4(7)

D = 6 + 28

D = 34

Therefore, Dave worked for 34 hours .

2. Determination of the perimeter.

Length (L) = 64 cm

Width (W) = 22 cm

Perimeter (P) =?

P = 2(L + W)

P = 2 (64 + 22)

P = 2 (86)

P = 172 cm

Therefore, the perimeter of the rectangle is 172 cm

Answer:

Money raised($)= 6n-50

Step-by-step explanation:

they plan to sell the hats for $10. each hat $4 to make and they spend $50 for advertising.

If their are no number of hats

Cost = 50+4n

Money gotten from the n number of hats= 10(n)

If they are to make profit, the money gotten from the sales of hats should be bigger than the total cost

Money raised = money from sales- cost

Money raised= 10n -4n-50

Money raised($)= 6n-50

The answer is (10-4)n-50

You subtract the amount of money used to make the hat from the price they are selling the hats. You then multiply that by the number of hats they sold. Then you subtract that from the amount of money spent on advertisement. Therefore the answer is (10 - 4) n - 50

83 divided by 5 is 16.6 if you need to round that, the answer would be 17

The quotient of the equation when A = 83/5 = 16.6

Given data ,

Let the quotient of the expression be represented as A

Now , the value of A is

Let the first number be represented as p

Now , the value of p = 83

Let the second number be represented as q

Now , the value of q = 5

where A = p/q

On simplifying the equation , we get

A = 83 / 5

A = 16.6

Therefore , the quotient of the expression is A = 16.6

Hence , the expression is A = 16.6
