Answer:
375 miles
Explanation:
The gas mileage of the scooter = 75 miles for each gallon of gasoline.
Therefore:
If 1 gallon will cover a distance of 75 miles
Then: 5 gallons will cover a distance of:
5 x 75 miles
=375 miles
Matt will be able to drive 375 miles on 5 gallons of gasoline.

1) In this problem, we need to make use of the order of operations.
2) Notice that we have divisions, so let's prioritize the division inside the parentheses, we can also rewrite another one, like this:
[tex]\begin{gathered} 10\div(-6--6\div6) \\ 10\div(-6-(-6)\div6) \\ 10\div(-6-(-1)) \\ 10\div(-6+1) \\ 10\div(-5) \\ -2 \end{gathered}[/tex]Notice that minus outside the parentheses work like a product (-1) x
2) Thus the answer is -2
The Senior classes at High School A and High School B planned separate trips to the indoor climbing gym. The senior class at High school A Rented and Filled 6 vans and 7 buses with 471 students. High School B rented and Filled 5 vans and 9 buses with 573 students. Every van had the same number of students in it as did the buses. How many students can a van carry? How many Students can a bus carry?
Answer: A van can carry 12 students
A bus can carry 57 students
Explanation:
Let x represent the number of students that a van can carry
Let y represent the number of students that a bus can carry.
The senior class at High school A Rented and Filled 6 vans and 7 buses. This means that
the number of senior class students that the van carried is 6 * x = 6x
the number of senior class students that the bus carried is 7 * y = 7y
If both vehicles were filled with 471 students, it means that
6x + 7y = 471 equation 1
High School B rented and Filled 5 vans and 9 buses. This means that
the number of High School B students that the van carried is 5 * x = 5x
the number of High School B students that the bus carried is 9 * y = 9y
If both vehicles were filled with 573 students, it means that
5x + 9y = 573 equation 2
We would solve both equations by applying the method of elimination. To eliminate x, we would multiply equation 1 by 5 and equation 2 by 6. The new equations are
30x + 35y = 2355 equation 3
30x + 54y = 3438 equation 4
Subtracting equation 3 from equation 4, we have
30x - 30x + 54y - 35y = 3438 - 2355
19y = 1083
y = 1083/19
y = 57
Substituting y = 57 into x equation 1, we have
6x + 7 * 57 = 471
6x + 399 = 471
6x = 471 - 399 = 72
x = 72/6
x = 12
Thus,
A van can carry 12 students
A bus can carry 57 students

What is the determinant of H= 0 2 3-1 3 56 3 -2
1) Since this is a Matrix 3x3 we can make use of the Sarrus Rule to find the determinant of this Matrix:
[tex]\begin{bmatrix}0 & 2 & 3 \\ -1 & 3 & 5 \\ 6 & 3 & -2 \\ \end{bmatrix}[/tex]2) We can do that by copying two columns to the right of the Matrix, and multiplying the entries, this way:
Now, let's add algebraically each diagonal and subtract from the other like this:
[tex]\begin{gathered} \det (H)=\lbrack60-9+0\rbrack-\lbrack54+4+0\rbrack \\ \det H)=51-58 \\ \det (H)=-7 \end{gathered}[/tex]which of these is an example of a proportional relationship
A proportional relationship is essentially a function where the output is a direct product of the input and the coefficient. Any relationship that has another constant term is not a proportional relationship because the final product is offset by the constant term.
The final answer where Samuel earns $20 for each lawn he mows can be expressed as 20x. This is a proportional relationship because the total money he earns is a product of the rate and x-value.

Yes 6 is the solution of the equation because replacing x with 6 and simplifying on the left side results in - 2, which equals the right side.
What is the basic equation?When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. An equation is an algebraic statement that demonstrates two mathematical expressions are equivalent in algebra, and this is how it is most usually used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal." When two expressions are joined by an equal sign, a mathematical statement is called an equation.
The given equation is x - 9 = - 3.
The given solution to the equation is 6.
Put 6 in place of x in the equation
6 - 9 = - 3
- 3 = - 3
So, the left-hand side of the equation is equal to the right-hand side. So, 6 is the solution to the equation x - 9 = - 3..

A school sells adult tickets and student tickets for a play. It collects $1,400 in total The graph shows the possible combinations of the number of adult tickets sold and the number of student tickets sold. What does the vertical intercept (0.200) tell us in this situation? O (1 Point) It tells us the decrease in the sale of adult tickets for each student ticket sold It tells us that if no adult tickets were sold, then 200 student tickets were sold It tells us that is no students tickets were sold, then 200 adult tickets were sold It tells us the decrease in the sale of student tickets for each adult ticket sold.
In the graph, the horizontal axis represents the number of adult tickets sold
And the vertical axis represents the corresponding number of student tickets sold.
The vertical intercept, as we are indicated is at (0,200)
That point is at 0 in the horizontal axis and at 200 on the vertical axis, comparing with what each axis represents:
(0,200) represents that when 0 adult tickets are sold, 200 student tickets are sold.
Answer:
it tells us that if no adult tickets were sold, 200 student tickets were sold

for the arithmetic sequence 42, 32, 22, 12... find the 18th term.
Answer:
The18th term of the given sequence is -128
Explanation:
To find the 18th term of the sequence:
42, 32, 22, 12, ..., we need to find the nth term of the sequence first.
The nth term of a sequence is given be the formula:
[tex]T_n=a+(n-1)d[/tex]Where a is the first term, and d is the common difference.
Here, a = 42, d = 32 - 42 = -10
[tex]\begin{gathered} T_n=42+(n-1)(-10) \\ =42-10n+10 \\ T_n=52-10n \end{gathered}[/tex]To find the 18th terem, substitute n = 18 into the nth term

The employee's original wage is $14.41 per hour.
If the wage increases by 4%, the percentage increase will be:
[tex]\Rightarrow\frac{4}{100}\times14.41=0.58[/tex]Therefore, the new wage per hour will be:
[tex]\Rightarrow14.41+0.58=14.99[/tex]The new wage is $14.99.
Write the equation of the horizontal line that goes through the point (9, 6).
Given the point:
(x, y) ==. (9, 6)
Let's write the equation of the horizontal line that goes through the given point.
On a horizonal line, every point on the line has the same value of y.
The slope of a horizontal line is 0.
Since every point on a horizontal line has the same value of y, to find the equation of a horizontal line, we are to use the y-coordinate of the point to find the equation of the horizontal line.
We have:
y-coordinate of the point = 6
Hence, the equation of the horizontal line that goes through the point is:
y = 6

which statement best describes the association between the energy and light output of these light bulbs?
As we can see from the graph, we can see that we could have two populations of lightbulbs in the graph. If we draw or try to approximate a line to these two different populations of lightbulbs, we end up with the next graph:
Then, we can conclude that, for most cases, as the energy increases, the light output increases too. Of course, there are some exceptions like the point (18, 800), but the tendency is in this way.
Therefore, the statement that best describes the association between the energy and light output is statement F: As the energy increases, the light output increases.
