Answer:
d = all real numbers
Step-by-step explanation:
-9d-8= -4 (d + 2) - 5d
-9d - 8 = -4d - 8 - 5d
-9d - 8 = -9d - 8
0d - 8 = -8
0d = 0
d = all real numbers
Juan and Dylan are selling bottled water. Juan sold 4 bottles for every 6 that Dylan sold. Dylan sold 16 more bottles than Juan. How many did each boy sell?
Answer:
Dylan sold 48 bottles
Juan sold 32 bottles
Step-by-step explanation:
The ratio of bottles sold is;
J:D = 4:6
Dylan sold 16 more than Juan
That means d = j + 16
so;
j/j + 16 = 4/6
6j = 4(j + 16)
6j = 4j + 64
6j - 4j = 64
2j = 64
j = 64/2
j = 32
d = j + 16
d = 32 + 16
d = 48

The number of workers, f(x), needed to complete a building is given by the function below where x represents the number of floors in the building.
Select the correct statement.
When f(3) = 18, the 3 represents the the number of workers needed and the 18 represents number of floors.
When f(3) = 18, the 3 represents the number of floors and the 18 represents the number of workers needed.
When f(4) = 48, the 4 represents the number of floors and the 48 represents the number of workers needed.
When f(4) = 48, the 4 represents the the number of workers needed and the 48 represents number of floors.
Answer:
When f(4) = 48, the 4 represents the number of floors and the 48 represents the number of workers needed.

graph the function. label the vertex and axis of symmetry
f(x) = -6x^2 - 4x - 5
Answer:
Vertex is (-1/3, -13/3)
Axis of symmetry is x = -1/3
Step-by-step explanation:
For the vertex, you need to change it into vertex form which is y = a(x - h)^2 + k
Vertex form for this equation is:
Y = -6(x + 1/3)^3 - 13/3
To find the vertex, the formula is (h,k)
So, ( -1/3, -13/3)

Consider f(x) = 1.8x – 10 and g(x) = −4
Select the equation that can be used to find the input value at which f (x ) = g (x ), and then use that equation to find the input, or x -value.
A) 1.8x – 10 = –4; x = 10/3
B) 1.8x = –4; x = 1.8 x = -20/9
C) 1.8x – 10 = –4; x = -10/3
D) -4 = x
Answer:B

buffy ate 100 fries in 5 minutes find her fry-eating rate in fries per minute
Answer:
20 fries per minute.
Step-by-step explanation:
If you express the number of fries per minute as 100/5 (as there are 5 minutes and 100 fries), assuming she ate at the same rate per minute, she had 20 fries per minute.
To check, multiply 20 by 5, in order to find out her fries per 5 minutes. It should be equal to 100.
Answer:
20 Fries per minute
Explanation:
20 fries x 1 minute = 100 fries in 5 min

51% of the tickets sold at a school carnival were early-admission tickets. If the school sold 100 tickets in all, how many early-admission tickets did it sell?
Answer:
51 were the total number of the tickets sold at a school carnival were early-admission tickets.
Step-by-step explanation:
Total number of tickets sold by = 100
Let [tex]x[/tex] be the early-admission tickets sold by the school.
As 51% of the tickets sold at a school carnival were early-admission tickets.
so
[tex]x=\frac{51}{100}\times 100[/tex]
[tex]= 51[/tex]
Therefore, 51 were the total number of the tickets sold at a school carnival were early-admission tickets.

Factor 6c - 8d
help please!
Answer:
6c - 8d = 2 (3c - 4d)
Step-by-step explanation:
Factoring
To factor a polynomial, we must find the Greatest Common Divisor (GCD) among all its terms.
The expression to factor is 6c - 8d.
The GCD is found by factoring all terms:
6c : 2,3,c
8d : 2,2,2,d
And take the common divisor between the coefficients and the variables
GCD=2
Thus, the factorization is:
6c - 8d = 2 (3c - 4d)
Enunciado:Si una empresa determina que sus costos obedecen a un modelo lineal y además sabe que si produce $10$ unidades sus costos totales son de $4000$ dólares y que si produce $15$ unidades sus costos ascienden a $5000$ dólares, entonces la función que modela sus costos totales es:
Responder:
y = 200x + 2000
Explicación paso a paso:
Deje que la ecuación lineal se exprese como y = mx + c
m es la pendiente
c es la intersección
Si la empresa produce $ 10 unidades, sus costos totales son $ 4000 dólares y si produce $ 15 unidades sus costos ascienden a $ 5000 dólares, entonces podemos representar esto como puntos de coordenadas;
(10,4000) y (15,5000)
Conseguir la pendiente
m = 5000-4000 / 15-10
m = 1000/5
m = 200
Obtener la intersección c
Sustituya m = 2000 y el punto (10, 4000) en la fórmula y = MX + c
4000 = 200 (10) + c
4000-2000 = c
c = 2000
Sustituya m = 200 y c = 2000 en la ecuación y = mx + c
y = 200x + 2000
Por tanto, la expresión lineal requerida es y = 200x + 2000
Last year during the hurricane season the amount of rain that fell on the texas gulf coast in october was 14 inches which was 3 1/2 times more than the rainfall during the month of september ?
Given :
Last year during the hurricane season the amount of rain that fell on the Texas gulf coast in October was 14 inches which was 3 1/2 times more than the rainfall during the month of September.
To Find :
Amount of rainfall in September.
Solution :
Let, amount of rainfall in September is x.
It is given that rainfall in October is 3 1/2 = 7/2 times of september.
So,
[tex]\dfrac{7}{2}x=14\\\\x = 4\ inches[/tex]
Therefore, rainfall in October is 4 inches.
Hence, this is the required solution.

Hey so I need some help.
Is this the right answer? Or is it different? Thanks for any help <3
Answer: Yes, your answer would be correct.
Step-by-step explanation:
Reason:
y= -1/2(2) + 11 = 10
y = -1/2(4) + 11 = 9
y = -1/2(6) + 11 = 8
y = -1/2(8) + 11 = 7
All of the values are correct when plugged in.

The price for chips have increased by 12% in recent years.If the approximate price for chips today is 2.50, how much was original price before the increase?
Answer:
Approximately $2.232
Step-by-step explanation:
Given that:
Percentage increase in Price of chips = 12%
Approximate price of chips today = $2.50
Original price before the increase :
Let original price = y
(Original price) + (12% of original price) = approximate price today
y + (12% of y) = $2.50
y + 0.12y = 2.50
1.12y = 2.50
Divide both sides by 1.12
1.12y / 1.12 = 2.50 / 1.12
y = 2.2321428
y = $2.232
Hence, original price of chips is approximately $2.232
