Answer:
To eliminate y- terms
Multiply equ(1) by 3 and equ(2) by -4
To eliminate y- terms
Multiply (1) by 3 and (2) by -5
Step-by-step explanation:
5x - 4y = 28 (1)
3x - 3y = 30 (2)
To eliminate y- terms
Multiply equ(1) by 3 and equ(2) by -4
15x-12y=84
-12x+12y= -120
Add equ (3) and (4)
3x=84-120
3x=-36
x=-36/3
= -12
x=-12
To eliminate x- terms
5x-4y=28
3x-3y=30
Multiply (1) by 3 and (2) by -5
15x-12y=84
-15x+15y=-150
Add the new equation
3y= -66
y= -22

Answer:
75.96 Degrees
Step-by-step explanation:
Use the trigonometric functions of Sine Cosine and Tangent
(SOH CAH TOA)
The unknown angle is near the adjacent side of 2 and the opposite side of 8
Therefore you use the Tangent function
However, since it's the angle that needs to be found, you need to use Arc Tangent (The inverse operation)
Unknown Angle = ArcTan (8 / 2)
Unknown Angle = 75.96 Degrees
Note: ArcTan is just Tan to the power of -1
On my calculator I have to click shift then click the tan function to access this it may be different on yours
Getaway Travel Agency surveyed a random sample of 454545 of their clients about their vacation plans. Of the clients surveyed, 212121 expected that they would go on 333 vacations in the next year. There are 516516516 Getaway Travel Agency clients.
Based on the data, what is the most reasonable estimate for the number of Getaway Travel Agency clients who expect to go on 333 vacations in the next year?
Answer:
The most reasonable estimate for the number of Getaway Travel Agency clients who expect to go on 3 vacations in the next year is 241.
Step-by-step explanation:
The best estimate for the proportion of clients who expect to go on 3 vacations is the same proportion of the sample.
Sample:
45 clients.
Of those, 21 expected to go on 3 vacations in the next year.
21/45 = 0.4667
Out of the 516 clients:
0.4667*516 = 240.8
Rounding up
The most reasonable estimate for the number of Getaway Travel Agency clients who expect to go on 3 vacations in the next year is 241.

Datos solu
Answer:
a. A Estela le entregaron (100 + 30 + 3) tejuelones = 133 tejuelones y aún necesita (138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido. b. Don Antonio llevó (150 + 60 + 7) tejuelones = 217 tejuelones.
Step-by-step explanation:
Parte a¿Cuántos tejuelones le entregaron a Estela? ¿Cuántos tejuelones es la diferencia para que Estela reciba todo el pedido realizado?
Datos
Pedido de Estela:
138 tejuelones.
Le entregaron:
Dos (2) Paquetes de 50 tejuelones.
Dos (2) Paquetes de 15 tejuelones.
Tres (3) Sueltos.
Operación
Para determinar cuántos tejuelones le entregaron a Estela, efectuamos las siguientes operaciones para determinar el número de tejuelones que le entregaron:
Dos (2) Paquetes de 50 tejuelones
2 * 50 tejuelones = 100 tejuelones
Dos (2) Paquetes de 15 tejuelones
2 * 15 tejuelones = 30 tejuelones
Es decir, multiplicamos el número de paquetes por la cantidad de tejuelones que trae cada uno.
Ahora sumamos el total de ambas cantidades y le adicionamos los tres (3) tejuelones sueltos:
(100 + 30 + 3) tejuelones = 133 tejuelones.
Pero Estela pidió 138 tejuelones, así que aún necesita:
(138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido realizado.
Respuestas
¿Cuántos tejuelones le entregaron a Estela?
A Estela le entregaron (100 + 30 + 3) tejuelones = 133 tejuelones.
¿Cuántos tejuelones es la diferencia para que Estela reciba todo el pedido realizado?
Estela aún necesita (138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido.
Parte b¿Cuántos tejuelones llevó Don Antonio?
Datos
Pedido de Don Antonio
Tres (3) paquetes de 50 tejuelones.
Cuatro (4) paquetes de 15 tejuelones.
Siete (7) tejuelones sueltos.
Operaciones
Para determinar cuántos tejuelones le entregaron a Don Antonio, debemos multiplicar el número de paquetes por la cantidad de cada uno y sumar los siete (7) tejuelones sueltos, es decir, seguimos el mismo procedimiento de la pregunta anterior.
Tres (3) paquetes de 50 tejuelones
3 * 50 tejuelones = 150 tejuelones.
Cuatro (4) paquetes de 15 tejuelones
4 * 15 tejuelones = 60 tejuelones.
Ahora sumamos estas cantidades y le adicionamos los siete (7) tejuelones sueltos:
(150 + 60 + 7) tejuelones = 217 tejuelones.
Respuesta
¿Cuántos tejuelones llevó Don Antonio?
Entonces, considerando los resultados anteriores, tenemos que Don Antonio llevó (150 + 60 + 7) tejuelones = 217 tejuelones.

The ratio of ages of kissi and esinam is 3:5 and esinam is 3:5 The sum of ages of all 3 is 147 years.whats the age difference between oldest and youngest ?
Answer:
48 years.
Step-by-step explanation:
Consider the complete question is "The ratio of ages of kissi and esinam is 3:5 and that of esinam and lariba is 3:5. The sum of ages of all 3 is 147 years. whats the age difference between oldest and youngest ?"
It is given that
Kissi : Esinam = 3:5 = 9:15
Esinam : Lariba = 3:5 = 15:25
So, the combined ratio is Kissi : Esinam : Lariba = 9:15:25
Let ages of Kissi, Esinam, Lariba are 9x, 15x and 25x.
Sum of ages of all 3 is 147 years.
[tex]9x+15x+25x=147[/tex]
[tex]49x=147[/tex]
[tex]x=3[/tex]
The value of x is 3. So, the age of all three are
[tex]Kissi=9x=9(3)=27[/tex]
[tex]Esinam=15x=15(3)=45[/tex]
[tex]Lariba=25x=25(3)=75[/tex]
Since Lariba is oldest and Kissi is youngest, therefore, the difference between their ages is
[tex]75-27=48[/tex]
Hence, difference between oldest and youngest is 48 years.

Estimate the measure of ∠DBC.
Answer:
135°
Step-by-step explanation:
Considering it's estimation, there isn't too much of an explanation, but here you go anyways.
A straight angle is equal to 180°. DBE is a straight angle.
DBC and CBE added together appear to be 180° (supplementary).
We are trying to find DBC. An obtuse angle has to be over 90°, which in this case DBC clearly is over 90°. From that you can conclude it isn't any of the first 3, so it's D. 135°

Find the equation of a line parallel to y = 2x + 4 that goes through the point (2,5)
Answer:
y= 2x+1
Step-by-step explanation:
Line parallel to y = 2x + 4
And that goes through the point (2,5)
-----------
Parallel lines have equal slope, so it will be in the form of y= 2x+b
Let's find the value of y-intercept (b) by using the given point:
5= 2*2+bb= 5-4b= 1So the line is: y= 2x+1

please mark brainiest
83% of 408 pounds is 338.64 pounds,41% of 53 kg is 21.73kg, 97% of 345 m is 334.65m
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We need to find
a)83% of 408 pounds
Firstly we need to convert 83% to decimal by dividing with 100.
83/100=0.83
Now multiply 0.83 with 408
0.83×408=338.64
b)41% of 53 kg
Firstly we need to convert 83% to decimal by dividing with 100.
41/100=0.41
Now multiply 0.41 with 53
0.41×53=21.73
c)97% of 345m
Firstly we need to convert 97% to decimal by dividing with 100.
97/100=0.97
Now multiply 0.97 with 345
0.97×345=334.65m
Hence 83% of 408 pounds is 338.64 pounds,41% of 53 kg is 21.73kg, 97% of 345 m is 334.65m

The graph would have a closed circle because it's less than or equal to
-7 is a part of the solution because it's less than or equal to -7
Answer:
Step-by-step explanation:
Subtract 22 from both sides to get [tex]x\leq -7[/tex]. So the 2nd one is correct
The sign is less than or equal to, so the graph does indeed have a closed circle. So the 3rd one is also correct
The answer is x is less than or EQUAL to -7, so -7 is included in the asnwer. So the 5th one is also correct
