NUMBER 1

This is a trick to solve any proportion.

Multiply the diagonal numbers.

5(16)=80

Divide by the number that isn't the one you want to find.

90/8=10

And you are left with the number you haven't touched. We haven't touched x, so x=10.

NUMBER 2

Cross multiply.

45(-50)=-2250

Divide.

-2250/3=-750

So x=-750.

QUESTION 3

4(27)=108

108/12=9

So x+3=9, subtract 3 from both sides x=6.

Answer:

- x³ - 9x²

Step-by-step explanation:

Given

- (3x³ + x² ) + 2(x³ - 4x² ) ← distribute both parenthesis

= - 3x³ - x² + 2x³ - 8x² ← collect like terms

= - x³ - 9x²

The expression in the simplest form is -x³ - 9x².

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is - (3x³ + x² ) + 2(x³ - 4x² )  will be solved as below:-

E = - (3x³ + x² ) + 2(x³ - 4x² )

E = - 3x³ - x² + 2x³ - 8x²

E = - x³ - 9x²

Therefore, the expression in the simplest form is -x³ - 9x².

Answer:

I will answer in English.

This can be translated to:

"Camila bought two books to read this vacation.  One is science fiction and the other is a novel.  If she finishes both books, she will have read 450 pages on vacation. The novel is known to have 60 pages  more than the science fiction book. Denoting by x  the number of pages in the fiction book and by y the number  pages of the novel book, it is possible to describe  a linear system with two equations involving x and  y with this information. "

First, the datat that we have is:

x + y = 450.

x + 60 = y.

Then we can isolate y in both equations, and have two linear equations:

y = 450 - x

y = x + 60.

Now we can graph those lines, and find the image bellow.

The point where the lines intersect is the solution of the system

We also can find the solution of the system as follows:

y = 450 - x = x + 60

then we can solve this for x.

450 - x = x + 60

2x = 450 - 60 = 390

x = 390/2 = 195

and we know that:

y = x + 60 = 195 + 60 = 255

Then: The science fiction book has 195 pages, and the novel has 255 pages.

A solução para os problemas levantados é:

1. O sistema linear com duas equações envolvendo as informações fornecidas é:

2. O gráfico que descreve este sistema no plano cartesiano pode ser encontrado como uma imagem anexa.

Obtenção e resolução do sistema de equações.

Levando em consideração que as variáveis ​​atribuídas são:  

A primeira frase menciona que se Camila terminar de ler os dois livros, ela terá lido 450 páginas, portanto, sabemos que a soma das páginas dos dois livros dará um total de 450, e na hora de escrever a equação:

Por outro lado, o depoimento diz que o livro de romance tem 60 páginas a mais que o livro de ficção, ou seja, o livro de ficção mais 60 páginas seria igual ao livro de romance, portanto, a equação seria:

Agora, você pode resolver o sistema de equações para ver o valor de x, substituindo a segunda equação na primeira:

Agora está calculado e com a segunda equação:

Desta forma, você pode ver que o livro de ficção científica tem 195 páginas, enquanto o romance tem 255 páginas.

Answer:

y = 5

Step-by-step explanation:

Answer:

y=5

Step-by-step explanation:

10/5y-13=-3

add thirteen to both sides

10/5y=10

multiply both sides by five

10y=50

divide both sides by 10

y=5

Answer:

x=14

Step-by-step explanation:

2 times x = 2x and 2 time 9 is 18 so the equation is 2x-18=10. then you add 18 to both sides and get 2x=28 then simplify to x=14

Answer:

x=14

Step-by-step explanation:

2(x-9)=10

Step one - Simplify both sides

(2)(x)+(2)(-9)=10 (distribute)

2x+-18=10

2x-18=10

Step two - Add 18 to both sides

2x-18+18=10+18

2x=28

Step three - Divide both sides by 2

2x÷2 = 28÷2

x= 14

x=14

Answer:

  b)  f(3) is defined, but is not equal to the limit

Step-by-step explanation:

The portion of the function defined by the rational expression is equivalent to x/(x+3), which has a value of 1/2 at x=3. This is the limit of f(x) from the left or right as x approaches 3. However, the function is not defined at that point as 1/2. Rather, it is defined to be f(3)=1.

So, the limits at f(3) exist and are 1/2, but the function is defined as a different value there.

The only applicable statement is the second one.

Answer:

G. $9,200

Step-by-step explanation:

average depreciation = (amount of depreciation)/(number of years)

The amount of depreciation is the difference between the new cost and the current value.

amount of depreciation = $85,600 - $30,400 = $55,200

number of years = 6

average depreciation = (amount of depreciation)/(number of years)

average depreciation = ($55,200)/(6 years)

average depreciation = $9,200/year

Answer: G. $9,200

Answer:

Width is 20 inches.

Length is 44 inches.

Step-by-step explanation:

Recall that the perimeter of a rectangle is given by the formula:

[tex]P=2(l+w)[/tex]

Where l is the length and w is the width.

We know that the length is 4 more than double the width. In other words, we can write an equation for l:

[tex]l=4+2w[/tex]

Let's substitute this into the above equation. So:

[tex]P=2((4+2w)+w)[/tex]

Combine like terms:

[tex]P=2(4+3w)[/tex]

We are given that the perimeter is 128 (inches). So, substitute 128 for P and solve for w:

[tex]128=2(4+3w)[/tex]

Divide both sides by 2. The right side cancels:

[tex]64=4+3w[/tex]

Subtract 4 from both sides:

[tex]3w=60[/tex]

Divide both sides by 3:

[tex]w=20[/tex]

Therefore, our width is 20.

We can use the length formula we acquired previously to acquire length. We have:

[tex]l=4+2w[/tex]

Substitute 20 for w:

[tex]l=4+2(20)[/tex]

Multiply:

[tex]l=4+40[/tex]

Add:

[tex]l=44[/tex]

So, our length is 44.

And we width is 20.

And we're done!
