Answer:
n = 14
Step-by-step explanation:
let 'n' = the number
3n - 5 = 2n + 9
n - 5 = 9
n = 14
Answer:
14
Step-by-step explanation:
We have to replace the unknown quantity with "x" and work with it.
The result of multiplying a number by 3 and substracting 5
3x - 5
Is the same as
3x-5= (__)
Doubling the number and adding 9
3x- 5= 2x+9
Then we solve it like any equation
3x - 5 = 2x + 9
3x - 2x = 9 + 5
x = 14

how do i graph x+4y=8
Answer:
x = 8 y = 2
(8,2)
Step-by-step explanation:
You have to find the value of both x and y
x + 4y = 8
to find x you have to cancel out y so,
x + 4(0) = 8
x = 8
to find y you have to cancel out x
0 + 4y = 8
4y = 8
divide both sides by 4
y = 2
Hope this Helps!!!
By changing the equation to slope intercept form we draw the graph and graph is given in attachment.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Let us convert the equation of line x+4y=8 to slope intercept form.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
x+4y=8
4y=8-x
Divide both sides by 4
y=-x+2
Now let us find few point to draw the graph.
If x=0
y=2
If x=1
y=1
If x=2
then y=0
if x=3
then y=-1
Now plot (0, 2), (1, 1) and (3, -1) and draw the graph
Hence, by plotting the points (0, 2), (1, 1) and (3, -1) we draw the graph and the graph is in attachment.

The graph of x - y = 1 is plotted below
Plotting linear graphsThe given equation is:
x - y = 1
The equation can be rewritten as:
y = x - 1
This is of the form y = mx + 1
where m is the slope
c is the y-intercept
Compare the equation y = mx + 1 with y = x - 1
The slope, m = 1
The y-intercept, c = -1
The graph of the equation y = x - 1 is plotted below

Se necesitan cortar 3 cintas de 40 cm, 50 cm y 60 cm, en trozos igua-
les de manera que todas sean iguales y con la mayor longitud posible.
¿Cuántos trozos se cortarán?
Answer:
Se cortarán en 15 trozos.
Step-by-step explanation:
Para determinar la longitud de cada trozo tal que todos los trozos tengan la misma longitud, se descompone factorialmente cada número:
[tex]40 = 2\times 2 \times 2 \times 5[/tex]
[tex]50 = 2\times 5\times 5[/tex]
[tex]60 = 2\times 2\times 3\times 5[/tex]
Ahora, determinamos el factor común de los tres números. Se puede encontrar que los tres números comparten un 2 y un 5. Entonces, el factor común es:
[tex]r = 2\times 5 = 10[/tex]
Este factor común representa la longitud de cada segmento. La cantidad de elementos se obtiene al dividir la suma de longitudes de las cintas por el factor común:
[tex]x = \frac{40\,cm+50\,cm+60\,cm}{10\,cm}[/tex]
[tex]x = \frac{150\,cm}{10\,cm}[/tex]
[tex]x = 15[/tex]
Se cortarán en 15 trozos.

Answer:
$9 and $12
Step-by-step explanation:
Let "s" be small boxes and "L" be large boxes.
12*s + 6*L = $180
3*s + 2*L = $51
From the first equation:
L = ($180 - 12*s) / 6 = $30 - 2*s
Plug that into 2nd equation:
3*s + 2*($30 - 2*s) = 3*s + $60 - 4*s = $51
s = $9
L = $30 - 2*s = $30 - $18
L = $12

Answer:
[tex]?=240[/tex]
Step-by-step explanation:
We can let the [tex]?[/tex] be [tex]x[/tex]. Rewriting the proportion, we get:
[tex]\frac{50}{2000}=\frac{6}{x}[/tex]
Solving for [tex]x[/tex], we get:
[tex]\frac{50}{2000}=\frac{6}{x}[/tex]
[tex]50*x=2000*6[/tex] (Cross-Products Property)
[tex]50x=12000[/tex] (Simplify)
[tex]\frac{50x}{50}=\frac{12000}{50}[/tex] (Divide both sides of the equation by [tex]50[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=240[/tex] (Simplify)
Since [tex]?=x[/tex], we know that [tex]?=240[/tex]. Hope this helps!
