Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) I'd say rational number. If p and q are integers, then -(p/a) = (-p)/q = p/(-q). Interpret quotients of rational numbers by describing real-world contexts.
Answers
Given that p and q are integers,
then find out -(p/q) = (-p)/q = p/(-q)
with real world example.
First of all we have know about Integers
a whole number, a number that is not a fraction.
and secondly Rational numbers
A rational number is any number that can be expressed in the form p/q where 'q' is not equal to zero. The quotient of the rational number p/q is nothing but the result that we get when we divide 'p' by 'q'.
For real world contexts we put some value at the place of p and q.
let p=1
q=2
-(1/2) = (-1/2) =(1/-2)
by evaluate it we get ...
-1/2=-1/2=-1/2
Rules for Negative rational numbers
If the rational number takes the form -(p/q), then either p or q takes the negative value. It means that -(p/q) = (-p)/q = p/(-q).If numerator and denominator are of opposite signs.All are less than 0.Hence If p and q are integers, then -(p/a) = (-p)/q = p/(-q).

Answer:
Alright
Ignore the 20, We have 5(x-2)
Brackets mean Multiplication
So, Multiply 5 with x and multiply 5 with 2
=> 20 = 5x - 10
Transpose the 20 to the other side
the twenty being transposed to the other side becomes Minus because it is in plus
And bring 5x in front of the =
=> 5x = 20 - 10
=> 5x = 10
So now we have 5x but we need x so transpose the 5 to the other side
by transposing the five becomes division because its in positive so
=> x = 10 ÷ 5
=> x = 2

What do we mean by the distance formula?Distance is a numerical measure of the distance between two objects or points. The distance can be a physical length or an estimate based on other criteria in physics or everyday usage. The distance between two points A and B are sometimes denoted as |AB|.The distance formula: d = rtSo,
To begin, consider the distance formula: d = rtDividing by the coefficient of t yields the following equation for t: t = d/rRyan's rate of 4 miles per hour can be voiced in minutes as 4 miles per 60 minutes.

Which number contains digits where the hundreds digit is 1/10 the value of the thousands digit?
Answers
The number that contains digits where the hundreds digit is 1/10 the value of the thousand's digit is: 748917.
What is number system?A system of writing numbers is known as a number system. It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set. It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.Firstly, refer to the image attached for the complete question.
Now,
Given: The value of the digit in the hundreds place in 653,841 is: 800
Now, the following cases arise for the given options:
748,917Value of digit in the thousands place = 8000
=> 1/10 the value of the digit = [tex]\frac{1}{10}(8000) = 800[/tex]
749,817Value of digit in the thousands place = 9000
=> 1/10 the value of the digit = [tex]\frac{1}{10}(9000) = 900[/tex]
784,817Value of digit in the thousands place = 4000
=> 1/10 the value of the digit = [tex]\frac{1}{10}(4000) = 400[/tex]
797,481Value of digit in the thousands place = 7000
=> 1/10 the value of the digit = [tex]\frac{1}{10}(7000) = 700[/tex]

What are the coordinates of the vertex for the graph of g(x) = |x+6|
Answers
The vertex of the equation g(x) = I x ₊ 6 I is (₋6 , 0).
Given the equation is g(x) = I x ₊ 6 I
The equation of the absolute value function is:
y = I x ₋ h I ₊ k where (h , k) is the vertex.
When the input is 0, the vertical axis will be intersected by the graph of an absolute value function. The horizontal axis is not usually where they cross. Depending on how the graph has been moved and reflected, it may or may not cross the horizontal axis.
compare the given equation to the above form.
y = I x ₊ 6 I ₊ 0
y = I x ₋ (₋6) I ₊ 0
hence we (h,k) as (₋6 , 0)
Therefore the coordinates of the vertex are (₋6 , 0)

2x + 3y = 1200, 3x + 2y = 1300. what is the value of 5x + 5y using substitution method
Answers
The value of 5x + 5y is 2500 by substitution method.
According to the given question.
We have two equations
2x + 3y = 1200
3x + 2y = 1300
Since, we have to find the value of 5x + 5y by substitution method.
From equation 2x + 3y = 1200
2x = 1200 - 3y
⇒ x = [1200 -3y]/2
Substitute the value of x in 3x + 2y = 1300.
⇒ 3[1200 - 3y]/2 + 2y = 1300
⇒ 3[600 -3y/2] + 2y = 1300
⇒ 1800 - 9y/2 + 2y = 1300
⇒ 1800 + (4y - 9y)/2 = 1300
⇒ (4y - 9y)/2 = -500
⇒ -5y = -1000
⇒ y = 200
So,
x = [1200 - 600]/2 = 600/2 = 300
Thereofore, the value of 5x + 5y by substitution method is given by
5(300) + 5(200)
= 1500 + 1000
= 2500
Hence, the value of 5x + 5y is 2500 by substitution method.

The width of a rectangle is 3 less than its length find the width of the rectangle if its perimeter is 26ft
Answers
The width of rectangle is 5 feet.
Let us assume the length of rectangle to be x. So, the width of rectangle will be (x - 3).
Now, as per the known fact, perimeter, length and width of rectangle are related by the formula -
Perimeter = 2 × (length + width)
Keep the values in formula to find the value of width
26 = 2 × (x + x - 3)
Performing addition of variables inside the bracket
26 = 2 × (2x - 3)
Shifting 2 to other side of equation to find the value of x
2x - 3 = [tex]\frac{26}{2}[/tex]
Performing division to find the value of x
2x - 3 = 13
Shifting 3 to other side of equation to find the value of x
2x = 13 + 3
Performing addition to find the value of x
2x = 16
Shifting 2 as denominator to other side of equation to find the value of x
x = [tex]\frac{16}{2}[/tex]
Performing division to find the value of x
x = 8
So, length of rectangle is 8 feet
Width of rectangle = x - 3
Width of rectangle = 8 - 3
Width of rectangle = 5 feet
Hence, the width of rectangle is 5 feet.

b. Use a graphing calculator to graph the function
Answers
The piecewise function describing the cost C of the reunion are C(x) = 500 + 17.5x, where x <= 40 and C(x) = 1200 + 14.75(x - 40), where x > 40
Write a piecewise function describing the cost C of the reunion.The given parameters are:
Reserve = $500
Cost per guest = $17.50 for the first 40 guests
Cost per guest = $14.75 for each additional guest
The above means that
C(x) = 500 + 17.5x, where x <= 40
C(x) = 500 + 17.5 * 40 + 14.75(x - 40), where x > 40
Next, we evaluate the functions
This gives
C(x) = 500 + 17.5x, where x <= 40
C(x) = 1200 + 14.75(x - 40), where x > 40

The Second and third car seats are appropriate for a 32-ib child
The first car :
The range 30 ≤x< 32
So it is not possible for a car seat appropriate for a 32-ib child.
The second car:
The range 15<x <40
So it is possible for a car seat appropriate for a 32-ib child.

Answers
The equation, in slope-intercept form, of the line zw is y = x.
It is given that, equation of the line pq is:-
y = -x + 2
Also, line pq is perpendicular to line zw
zw passes through the point z (11,11).
We have to find the equation, in slope-intercept form, of the line zw.
The slope intercept form of a line is:-
y = mx + b
Where,
m represents slope of the line,
(x,y) represents every point on the line
b represents the y-intercept of the line
We know that, when two lines are perpendicular, the product of slopes of the lines is -1.
Let the slope of the line zw be m.
Hence,
m*(-1) = -1
m = 1
As it passes from the point z(11,11).
Hence, we can write,
11 = 1(11) + b
11 = 11 + b
b = 0

equation which can be used to determine j, how much each bottle of juice cost.
Please include equation and answer(j= )
Answers
If the total cost before tax was $11.5, then the cost of each bottle of juice j= $1.6 which can be found by the equation 5j + $3.50 = $11.50.
The cost of each bottle can be determined by using an algebraic expression.
An algebraic expression can be defined as the use of both numerals and letters in a mathematical equation.
To find the cost of each bottle, an algebraic expression can be given as,
Cost of a 5-pack of juice bottles + Cost of popcorn = Total cost before tax
5j + $3.50 = $11.50
Solving for j,
5j = 11.50 - 3.50
5j = 8
j = 8/5
j = $1.6
