Answer:
[tex]BC=26[/tex]
Step-by-step explanation:
Start with:
[tex]AB+BC=AC[/tex]
Since [tex]B[/tex] is the midpoint, we also know that:
[tex]AB=BC[/tex]
Knowing this, we can use a system of equations and substitute [tex]AB[/tex] for [tex]BC[/tex] in the equation we started with:
[tex]AB+AB=AC[/tex]
Let's identify our values:
[tex]AB=3x-1\\AC=8x-20[/tex]
Substitute:
[tex]3x-1+3x-1=8x-20[/tex]
Combine like terms:
[tex]6x-2=8x-20[/tex]
Add [tex]20[/tex] to both sides of the equation:
[tex]6x+18=8x[/tex]
Subtract [tex]6x[/tex] from both sides of the equation:
[tex]18=2x[/tex]
Divide by the coefficient of [tex]x[/tex], which is [tex]2.[/tex]
[tex]x=9[/tex]
Substitute [tex]9[/tex] into [tex]3x-1[/tex]
[tex]3(9)-1[/tex]
Solve:
[tex]AB=26[/tex]
Remember that [tex]AB=BC[/tex], thus:
[tex]BC=26[/tex]

Answers
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!
At its highest point, the elevation of a county is 5,764 feet above sea level. At its lowest point, the elevation of the county is 7 feet below sea level. Answer parts a through c. a. Write an expression using integers to represent the difference between the elevations.

Step-by-step explanation:
Given
[tex]Highest\ Point = 5764\ feet[/tex]
[tex]Lowest\ Point = 7\ feet[/tex]
Required
Determine the difference between the points
The difference is calculated as follows:
[tex]Difference = Highest - Lowest[/tex]

Answer:

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:
x + y = 450x + 60 = y2. 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:
x = Número de páginas do livro de ficção.y = Número de páginas do livro do romance.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:
1. x + y = 450Por 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:
2. x + 60 = yAgora, você pode resolver o sistema de equações para ver o valor de x, substituindo a segunda equação na primeira:
x + y = 450x + (x + 60) = 450x + x + 60 = 4502x + 60 = 4502x = 450 - 60x = 390/2x = 195Agora está calculado e com a segunda equação:
x + 60 = y195 + 60 = y255 = yy = 255Desta forma, você pode ver que o livro de ficção científica tem 195 páginas, enquanto o romance tem 255 páginas.
