Answer:
Step-by-step explanation:
Based on the information provided we can create the following direct proportion equation...
D = 3.5x
In this equation, the variable D represents the distance that Brianna has walked while the variable x represents the number of hours she walked. In this equation, the constant of proportionality would be the 3.5 miles that Brianna walks per mile. This value affects the entire equation because it is multiplied by the number of hours Brianna walks which is directly proportional to the Distance she travels, as one value increases so does the other.

What happens to the mean of the data set {2, 4, 5, 6, 8, 2, 5, 6} if the number 7 is added to the data set?
Answer:
It increases
Step-by-step explanation:
The mean of the given data set of 8 values is 4.75 ([tex]\frac{2+4+5+6+8+2+5+6}{8}[/tex])
Adding 7 into the data set also increase the number of data points to 9, so the mean becomes:[tex]\frac{2+4+5+6+8+2+5+6+7}{9}[/tex], which is equal to 5

Solve the system by substitution.
y=6x
y=3x+21
( , )
Answer:
(7,42)
Step-by-step explanation:
Imput the 6x for the Y:
6x=3x+21
move the variable to the left
6x-3x=21
collect like terms:
3x=21
divide both sides by 3x and youll get this for X
x=7
Imput x=7 into the equation
Y=6x7
solve:
y=42

Marcus and Lara each have the same number of songs on their ipods. Marcus has 10x + 8 songs and Lara has
15x - 92 songs. What is x?
Answer:
The value of x is 20.
Step-by-step explanation:
Given that
Number of songs Marcus has = 10x+8
Number of songs Lara has = 15x-92
It is also given that they have the same number of songs that means both the expressions should be equal.
Putting both equal
[tex]10x+8 = 15x-92[/tex]
This is a linear equation in one variable which can be solved using properties of equality
Subtracting 10 from both sides
[tex]10x+8-10x = 15x-92-10x\\8 = 5x-92[/tex]
Adding 92 on both sides
[tex]8+92 = 5x-92+92\\100 = 5x[/tex]
Dividing both sides by 5
[tex]\frac{5x}{5} = \frac{100}{5}\\x = 20[/tex]
Hence,
The value of x is 20.

John takes out a loan for $ 12 , 000 at a simple interest rate of 4.5 % to be paid back in 36 monthly installments. What is the amount of the monthly payments?
Answer: $378.33
Step-by-step explanation:
First we calculate the Simple interest which will be:
= 12000 × 4.5% × 3
= $1620
Total amount to be paid = $12000 + $1620 = $13620
Since there are 36 monthly installments, the amount of the monthly payments would be:
= $13620 / 36
= $378.33

What is the equation of the line passing through the points (-4,3) and (2,7)?
Answer:
[tex]y = \frac{2}{3} x + \frac{17}{3}[/tex]
Step-by-step explanation:
First, find the slope of the line:
The formula for finding the slope is: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Plug in the points:
[tex]\frac{7 - 3}{2 - (-4)}[/tex] = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
So now the equation is y = [tex]\frac{2}{3}[/tex]x + b
Now solve for b by plugging in one of the points:
(2,7)
y = [tex]\frac{2}{3}[/tex]x + b
7 = [tex]\frac{2}{3}[/tex]2 + b
7 = [tex]\frac{4}{3}[/tex] + b
b = [tex]\frac{17}{3}[/tex]
So the equation will be [tex]y = \frac{2}{3} x + \frac{17}{3}[/tex]
Solve for y :3x-3y=12

There are 4 breakfast choices in a school cafeteria: Cereal, Granola Bar, Breakfast Sandwich, and Fruit. The percentage of students that chose cereal is 20%. If 60 students chose cereal, what is the total number of students that ate breakfast?
A.
120
B.
300
C.
320
D.
360
Answer:
300. In this case, it's very easy to do this percentage inflation. Since 20 is a multiple of 100, and we want to know the 100%, you just multiply the 20 by 5 to make it 100. Along with this, you multiply the 60 by 5 as well, which gives you 300.
