The price for the amount of fuel that Roselyn will use for the entire drive is $25
What is an Equation?An equation is a mathematical statement formed when two expressions are equated using an equal sign.
The equations are useful in the determination of unknown parameters.
The equations are of various types, such as Trigonometric equations, and quadratic equations.
Roselyn's family lives 150 km away.
Her average speed is 60km/h
The car tank has 20 L of fuel at the beginning of the the drive.
Fuel efficiency is 6km/ L.
The cost of the fuel is $0.60/L.
The total drive is 150km.
The 6km of distance requires 1 L of fuel
Then 150 km of the distance requires
= 150 * 1 / 6
= 150/6
= $25.

Paul wants to estimate the mean number of siblings for each student in his school. He records the number of siblings for each of 100 randomly selected students in the school. What is the parameter?
Answer:
A parameter is defined as a numerical or another measurable factor that conforms a set that defines a given system.
In this case, the only parameter that we have is the number of siblings that each one of the 100 students has.
For example, in a table:
#student #siblings.
1 3
2 1
3 4
... ...
In the left side, we have the "number of the student" that does not really matter, because the students are randomly selected, and at the right, we can see our only parameter in this study, that is the number of siblings that each student has.

[tex]Explanation:[/tex]
[tex]3(-x+4)=7x-8[/tex]
Let's start by simplifying both sides. First, we distribute.
[tex](3)(-x)+(3)(4)=7x+-8[/tex]
[tex]-3x+12=7x+-8[/tex]
[tex]-3x+12=7x-8[/tex]
Now let's subtract 7x from both sides.
[tex]-3x+12-7x=7x-8-7x\\-10x+12=-8[/tex]
Now we will subtract 12 from both sides.
[tex]-10x+12-12=-8-12\\-10x=-20[/tex]
In our last/final step, we will divide both sides by -10.

¿Cuál es el valor de 0.1561 redondeado a la décima más cercana?
A 0.15
B 0.16
C 0.1
D 0.2
Answer: 0.2
Step-by-step explanation: Necesitamos ajustar la estimación de 0.1561 al décimo más cercano.
El número después del decimal es el número en el décimo lugar. Considere el número a un lado del lugar de las décimas y utilice el número para decidir si se reunirán o seguirán siendo el equivalente. Observe que el número a un lado del décimo lugar es mayor o equivalente a 5 o menos de 5. En el caso de que ese número sea más digno de mención o equivalente a 5, en ese punto el número se reunirá aún en la remota posibilidad de que ese número es menor de 5, en ese momento el número no se reunirá. Permanecerá igual.
Consideremos el número dado 0.1561
El número en el lugar de las décimas es 1
El número después del punto de las décimas es 5 (que es más prominente o equivalente a 5)
De esta manera, el número se reunirá en 0,2

O Divide both sides of the inequality by 3. Change the direction of the inequality. Subtract 8 from both sides of the
inequality.
Answer:
Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.
Step-by-step explanation:
The given inequality is 3b + 8 ≥ 14
We need to solve the given inequality
Step 1.
Subtract 8 to the both sides of the inequality
3b + 8 - 8 ≥ 14 -8
3b ≥ 6
Dividing both sides by 3
b ≥ 2
The value of b is greater than and equal to 2.
Hence, the correct option is (a).

Find the x and y intercepts of the graph of the function
Answer:
y intercepts= 0 x intercepts= none
nation:
The 2 funtions above the x axis do not intercept with the y-axis or the x-axis. They just hover above it, but never atcually touch it.
The function bellow the x-axis only intercepts the y-axis at 0,0
The x and y intercepts of the graph of the function are x=none and y=-1 respectively.
From the given figure we need to find the x and y intercepts of the function.
What is x and y intercepts of the function?The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.
From the graph, we can see two curves running on x-axis.
The curve crosses the y-axis at y=-1.
Therefore, the x and y intercepts of the graph of the function are x=none and y=-1 respectively.

Answer:
x= -1
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
3x+2(x-9)=8x+x-14 ;; equation
simplify the equation to the form
3x+2(x-9)=8x+x-14
reorder the terms in parentheses
3x+(+2x-18)=8x+x-14
remove unnecessary parentheses
+3x+2x-18=+8x+x-14
move all terms containing x to the left and all other terms to the right.
+3x+2x-8x-1x=-14+18
simplify left and right side of the equation.
-4x=+4
divide both sides of the equation by -4 to get x.

Step-by-step explanation:
on a number line, point D is located at 9 and point P is located at -11 what is the distance from d to p
Answer:
20
Step-by-step explanation:
The distance between two points on the number line is the absolute value of the difference of their coordinates.
coordinate of point D: 9
coordinate of point P: -11
Take the absolute value of their difference. It does not make a difference in which order you subtract the coordinates.
distance = |-11 - 9| = |-20| = 20
Answer: The distance is 20.

A box contains 7 red, 14 yellow, 21 green, 42 blue, and 84 purple marbles. A marble is drawn at random from the box. Find the odds against drawing a purple or yellow marble.
A. 5 to 7
B. 5 to 12
C. 2 to 7
Answer:
B
Step-by-step explanation:
Here, we are to find the odds against drawing a purple or yellow marble.
Mathematically, the odds against drawing a particular marble color = 1 - the probability of drawing that particular marble color
probability of drawing a purple colored marble = number of purple colored marbles/total number of marbles
= 84/(84 + 42 + 21 + 14 + 7) = 84/168 = 1/2
So the odds against drawing a purple colored marble = 1 - 1/2 = 1/2
The odds against drawing a yellow marble color = 1 - probability of drawing a yellow colored marble
Probability of drawing a yellow colored marble = number of yellow marbles/total number of marbles = 14/168 = 1/12
So the probability of drawing a yellow colored marble or purple colored marble = 1/12 + 1/2 = 7/12
Now, the odds against drawing either of the two = 1 - the probability of drawing either of the 2 = 1 -7/12 = 5/12
or simply put 5 to 12
