Answer: {x,y} = {4,2}
[1] x - 4y = -4
[2] 5x - 4y = 12// Solve equation [1] for the variable x
[1] x = 4y - 4
// Plug this in for variable x in equation [2]
[2] 5•(4y-4) - 4y = 12
[2] 16y = 32
// Solve equation [2] for the variable y
[2] 16y = 32
[2] y = 2
// By now we know this much :
x = 4y-4
y = 2
// Use the y value to solve for x
x = 4(2)-4 = 4

Peggy takes 2.5 hours to deliver 328 magazines. What is the rate per hour she is delivering the magazines
Answer: 131 magazines per hour
Step-by-step explanation:
Peggy delivered 328 magazines in 2.5 hours.
To find out the rate at which she delivered these magazines, divide the number of magazines by the time taken to deliver them:
= Magazines / Time in hours
= 328 / 2.5
= 131 magazines per hour

Un agricultor planta 720 naranjos, 250 matas de mandarina, 360 de mamon y 480 de níspero en el menor número posible de hileras, cada una con el mismo número de árboles, sin mezclarlos. A) ¿Cuántos arboles tiene cada hilera? B) ¿Cuántas hileras necesita?
Answer:
A) Se requiere 10 árboles por hilera.
B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.
Step-by-step explanation:
A) A continuación, realizamos la descomposición factorial de cada número:
Naranjos
[tex]720 = 2 \times 2 \times 2 \times 2 \times 3\times 3\times 5[/tex]
[tex]720 = 2^{4}\times 3^{2}\times 5[/tex]
Mandarinos
[tex]250 = 2\times 5\times 5\times 5[/tex]
[tex]250 = 2\times 5^{3}[/tex]
Mamoneros
[tex]360 = 2\times 2\times 2\times 3\times 3\times 5[/tex]
[tex]360 = 2^{3}\times 3^{2}\times 5[/tex]
Nísperos
[tex]480 = 2\times 2\times 2\times 2 \times 2\times 3\times 5[/tex]
[tex]480 = 2^{5}\times 3\times 5[/tex]
El máximo común divisor de los cuatro números representa el número de árboles de cada hilera considerando el menor número posible de hileras, cuyo valor es [tex]2\times 5 = 10[/tex]. Se requiere 10 árboles por hilera.
B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por el resultado del punto anterior:
Naranjos
[tex]x = \frac{720}{10}[/tex]
[tex]x= 72[/tex]
Mandarinos
[tex]x = \frac{250}{10}[/tex]
[tex]x = 25[/tex]
Mamoneros
[tex]x = \frac{360}{10}[/tex]
[tex]x = 36[/tex]
Nísperos
[tex]x = \frac{480}{10 }[/tex]
[tex]x = 48[/tex]
El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.
Teniendo en cuenta la definición de m.c.m:
A) Se requieren 10 árboles por hilera.
B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.
A) Para hallar la cantidad de árboles que posee cada hilera debes hallas el m.c.d entre 720, 250, 360 y 480.
El máximo común divisor, m.c.d., de dos o más números es el mayor número que divide a todos de manera exacta, es decir, es el mayor de los divisores que tienen en común dos o más números.
El mínimo común múltiplo se suele expresar con las siglas m.c.d. (a, b), siendo a y b los números.
Para calcular el mínimo común múltiplo de dos o más números, de debe descomponer los números en factores primos (son los números que sólo son divisibles por sí mismos o por el número 1). En este caso:
720= 2×2×2×2×3×3×5= 2⁴×3²×5
250=2×5×5×5= 2×5³
360=2×2×2×3×3×5= 2³×3²×5
480=2×2×2×2×2×3×5= 2⁵×3×5
El mínimo común múltiplo se obtiene escogiendo todos los factores comunes, elevados a la menor potencia. Es decir, se escoge aquellos factores que aparecen en todas las descomposiciones la menor cantidad de veces. En este caso:
mcd (720,250,360, 480)= 2×5= 10
Entonces, se requiere 10 árboles por hilera.
B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por la cantidad de árboles que se requiere por hilera:
Naranjos: 720÷10= 72
Matas de mandarina: 250÷10= 25
Mamon: 360÷10= 36
Níspero: 480÷10= 48
El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

Answer:
MC is 10 in.
Step-by-step explanation:
The given parameters for the triangle ΔABC are;
m∠B = 90°
m∠C = 15°
M ∈ BC
m∠BAM = 60°
AM = 10 in.
From the given information, ΔABC is drawn using Microsoft Visio, from which we have ΔACM
m∠CAM = 75° - 60° = 15° (By angle addition postulate)
m∠CAM = 15° = m∠C, therefore, ΔACM is an isosceles triangle with base angles, m∠CAM and m∠C each equal to 15°
AM = 10 in. = MC, by definition of isosceles triangle
∴ MC = 10 in.
Use the table to write a linear function that relates y to x.
y=
Answer:
A linear function that relates y to x is:
[tex]y\:=\:\frac{2}{3}x\:+\:5[/tex]
The graph of the linear function is also attached.
Step-by-step explanation:
Given the table
x -3 0 3 6
y 3 5 7 9
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptTaking two points (-3, 3) and (0, 5) from the table to determine the slope of the linear function
(x₁, y₁) = (-3, 3) (x₂, y₂) = (0, 5)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [5 - 3] / [0 - (-3)]
= 2 / 3
Thus, the slope of the line = m = 2/3
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the table, it is clear
at x = 0, y = 5
Thus, the y-intercept b = 5
substituting m = 2/3 and b = 5 in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y\:=\:\frac{2}{3}x\:+\:5[/tex]
Therefore, a linear function that relates y to x is:
[tex]y\:=\:\frac{2}{3}x\:+\:5[/tex]
The graph of the linear function is also attached.
A school carnival sold 90 early-admission tickets and 810 regular tickets. What percentage of the tickets sold were early-admission tickets?
Answer:
11.12 %
Step-by-step explanation:
Given that,
There are 90 early admission tickets.
There are 810 regular tickets.
We need to find the percentage of the tickets sold were early-admission tickets.
[tex]P=\dfrac{90}{810}\times 100\\\\=11.12\%[/tex]
So, the required percentage is 11.12 %.

V = four-thirds (11) pi
V = two-thirds (11) pi
V = four-thirds (11)
V = two-thirds (11)
9514 1404 393
Answer:
V = (2/3)(11)
Step-by-step explanation:
The given cylinder has a height of 2r, so its volume is ...
V = πr²(2r) = 2πr³
The volume of a sphere is given by ...
V = 4/3πr³
Then the ratio of the volume of the sphere to the volume of the cylinder is ...
(4/3πr³)/(2πr³) = (4/3)/2 = 2/3
So, the volume of the sphere is 2/3 times the volume of the cylinder:
V = (2/3)(11)

If O is the center of the circle find x.
Answer:
x = 60°
Step-by-step explanation:
Angles on the circle formed by the same arc are congruent, then
∠ BDC = ∠ BAC = 50°
x = 180° - (70 + 50)° ← sum of angles in triangle = 180°
x = 180° - 120° = 60°
1,200 divided by 5 times 10
Answer:
24
Step-by-step explanation:
Multiply 5 * 10
5 * 10 = 50
1,200/50 = 24
The result of 1,200 divided by 5 times 10 is 2,400.
To solve the expression, follow the order of operations (PEMDAS/BODMAS):
1,200 ÷ 5 × 10
Step 1: Perform division first:
1,200 ÷ 5 = 240
Step 2: Perform multiplication:
240 × 10 = 2,400
So, the result of 1,200 divided by 5 times 10 is 2,400.

Answer: The next fraction in the sequence will be 5/20.
Step-by-step explanation:
9/20 is the first fraction.
2/5 is equal to 8/20, so that is the second fraction.
7/20 is the third fraction.
3/10 is equal to 6/10, so that is the fourth fraction.
By now we can see that there is a pattern, because the first fraction's numerator began with 9, the next 8, then 7, and 6. We also simplfied all he fractions so that they had the denominator 20. Because of this, the next fraction in the sequence will be 5/20.
