Answer:
x ∈ (-∞, 9) U (-1, ∞)
Step-by-step explanation:
Get the absolute value by itself. Do that by multiplying by 4.

This resolves to two cases:
3x +15 > 12
x +5 > 4 . . . . divide by 3
x > -1 . . . . . . .subtract 5
-(3x +15) > 12
x +5 < -4 . . . . divide by -3

The selling price of a refrigerator is $478.80 if the markup is 5% of the dealers cost, what is the dealers cost of the refrigerator
Answers
The dealer's cost of refrigerator is $456.
We are given the total selling price and mark up according to dealer's cost. So, let us assume the dealer's cost be x.
x + 5% × x = 478.80
Converting mark up percentage to fraction and then decimal form
x + 0.05x = 478.80
Performing addition on Left Hand Side of the equation to find the value of x
1.05x = 478.80
Shifting 1.05 to Right Hand Side of the equation
x = 478.80 ÷ 1.05
Performing division to Right Hand Side of the equation to find the value of x
x = 456
Hence, the dealer's cost will be $456.

Enter a value for x that makes the equation 7x - 2(x + 1) + 18 = 8x - 11 true.
Answers
Answer:
9
Step-by-step explanation:
The given equation is true for x=-5/3.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 7x-2(x+1)+18 = 8x-11.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The solution for the equation 7x-2(x+1)+18 = 8x-11 is as follows
7x-2x-2+18 = 8x-11
⇒ 5x-16=8x-11
⇒ 8x-5x=-16+11
⇒ 3x=-5
⇒ x=-5/3
Verification:
Substitute x=-5/3 in the given equation and verify
That is, 5(-5/3)-16=8(-5/3)-11
⇒ -25/3 -16=-40/3 -11
⇒ (-25-48)/3 = (-40-33)/3
⇒ -73/3 =-73/3
LHS = RHS
Therefore, the given equation is true for x=-5/3.

Se necesitan conductores voluntarios para llevar a 80 estudiantes al juego de béisbol del campeonato. Los conductores cuentan con automóviles, con capacidad para 4 estudiantes, o camionetas, con capacidad para 6 estudiantes. La ecuación describe la relación entre la cantidad de automóviles y la cantidad de camiones que pueden transportar exactamente 80 estudiantes.
Seleccione todas las afirmaciones que sean verdaderas sobre la situación.
a) Si van 12 coches, se necesitan 2 furgonetas.
b) c = 14 y v = 4 son un par de soluciones de la ecuación.
c) Si van 6 coches y van 11 furgonetas, habrá espacio adicional.
d) 10 coches y 8 furgonetas no son suficientes para transportar a todos los estudiantes.
e) Si pasan 20 autos, no se necesitan camionetas.
f) 8 furgonetas y 8 coches son números que cumplen con las limitaciones en esta situación.
Answer:
La opción b, e y f.
Step-by-step explanation:
Pasando por las opciones dadas:
c = coches que pueden llevar a 4 estudiantes
v = furgonetas con capacidad para 6 estudiantes
a) Si van 12 coches, se necesitan 2 furgonetas.
= 12 (4) + 2 (6)
= 48 + 12
= 60
60 ≠ 80
La opción a es incorrecta
b) c = 14 y v = 4 son un par de soluciones de la ecuación.
14 (4) + 4 (6)
56 + 24 = 80 estudiantes
La opción b es correcta
c) Si van 6 coches y van 11 furgonetas, habrá espacio adicional.
Por lo tanto:
5 (4) + 11 (6)
= 20 + 66
= 86.
86 es mayor que 80, la opción c es correcta, habría un espacio adicional para 6 estudiantes.
d) 10 coches y 8 furgonetas no son suficientes para transportar a todos los estudiantes.
Por lo tanto:
10 (4) + 8 (6)
40 + 48
= 88
e) Si pasan 20 autos, no se necesitan camionetas.
20 (4) = 80 estudiantes
La opción e es correcta
f) 8 furgonetas y 8 coches son números que cumplen con las limitaciones en esta situación.
8 (6) + 8 (4)
= 48 + 32
= 80 estudiantes.
La opción b es correcta
Por lo tanto, la ecuacióna que describe la relación entre la cantidad de automóviles y la cantidad de camiones que pueden transportar exactamente 80 estudiantes es la opción b, e y f.
Write the formula for the volume V of a cube with sides of length t. is V a function of t?
Answers
Answer:
The volume of a cube with the side length 't' will be:
V = t³
Yes! the volume of the cube is a function of the side length as the volume is a dependent quantity and depends on the value of side length.
Step-by-step explanation:
We have to determine the volume of a cubeWe know that volume is the measurement of how much space a 3-d object takes up.
Given that the cube with the side length 't'.
As every edge of the cube is the same length.
Thus, the volume of a cube with the side length 't' will be:
V = t³
For example, if the side length t = 2 cm
Then,
V = 2³ = 8 cm³
Yes, the volume of the cube is a function of the side length as the volume is a dependent quantity and depends on the value of side length.

a. What fraction of all the supporters are male and supporting the away
team?
b. What fraction of all the supporters are female and supporting the away

Answers
The fractions of all the supporters that are male and support the away
team is 1/3
The fractions of all the supporters that are female and support the away
team is 2/9.
What is a fraction?A fraction is a value representing a part of a whole.
We have,
Supporters for the Home team = 4/9
Supporting for the away team = 1 - 4/9 = 5/9
Now,
Male supporters from the away team = 3/5 x 5/9 = 1/3
So,
Female supporters from the away team = (1 - 3/5) x 5/9 = 2/5 x 5/9 = 2/9
Thus,
The fractions of all the supporters that are male and support the away
team is 1/3
The fractions of all the supporters that are female and support the away
team is 2/9.

On a school field trip, the bus travels 20 miles in 30 minutes. Find the speed of the bus in miles per hour. Use the equation d=rt, where d is distance, r is rate, and t is time.
Answers
Answer:
40mph
Step-by-step explanation:
Using D = rt, the current variables we have are
D = 20 miles
t = 30 minutes
Since the goal is rate, we alter the equation to r = D/t.
In addition, we have to convert minutes into hours so we can
r = (20 / 30)*2/2
r = (40/60)
60 minutes is converted into an hour so the rate r is 40 miles per hour.
r = 40/1

You recognize that the ratio of leg lengths of the right triangle involved is ...
6 : 8 = 3 : 4
You know that any right triangle with leg lengths 3 and 4 has a hypotenuse of 5. The ladder will need to be in the same ratio:
3 : 4 : 5 = 6 : 8 : 10
The ladder needs to be 10 meters long.
_____
In case you don't remember that (3, 4, 5) is a "Pythagorean triple," you can figure the length using the Pythagorean theorem.
6^2 +8^2 = hypotenuse^2
36 +64 = 100 = hypotenuse^2
hypotenuse = √100 = 10 . . . . required ladder length in meters
