The room numbers of two adjacent classrooms are two consecutive odd numbers. If their sum is 720, find the
classroom numbers.
The room numbers of two adjacent classrooms are 359 and 361.
What is consecutive odd numbers?
Consecutive odd numbers are odd integers that are separated by 2 and come after one another.
Suppose the first odd number is x, then the another consecutive odd number is x + 2.
The sum of these two numbers is 720.
So,
x + (x + 2) = 720
2x + 2 = 720
2x = 718
x = 359
Therefore, the first odd number is 359 and the second add number is 361 which gives the sum 720.

An integer number is a number that can be written without using a rational component. In other words, if a number can be written without using a fraction, then that number is considered an integer.
For example, let's take the first number:
[tex]-\frac{64}{8}[/tex]This number is written as a fraction. But, this is also equivalent to:
[tex]-\frac{64}{8}=-8[/tex]Since it can also be written without making use of a fraction then this number is an integer.
Also, there are numbers that are written in decimal form. For example:
[tex]-8.92[/tex]These types of numbers are not integers.
The value of x =5 is a solution to each of the following except which ?
A 3x+2=4x-3
B (x+2)(x-5)=0
C4x+2=15
D 3x-10=x
Answer:
The answer is C
Step-by-step explanation:
If you substitute every x value for 5, you know that every equation can have 5 as an answer but C.
A. 3x+2=4x-3
Isolate the x(s) and combine like terms
3x+2-2=4x-3-2
3x=4x-5
3x-4x=4x-4x-5
-x=-5
-x(-1)=-5(-1)
x=5
Therefore A is a solution
B. (x+2)(x-5)=0
Substitution--Substitute every x for a 5
(7)(0)=0
anything multiplied by 0 will be 0
B. Is a solution because it is true.
C. 4x+2=15
Isolating the x(s) and combine like terms
4x+2-2=15-2
4x=13
4x÷4=13÷4
x=3.25
C is not a solution because x should equal to 5 but in this equation x can only be equal to 3.25. C is wrong.
We know our answer so we don't have to keep solving the rest of the equations.
But I'll just do D
D. 3x-10=x
Isolate the x(s) and combine like terms
3x-x-10=x-x
2x-10=0
2x=10
2x÷2=10÷2
x=5
D is a solution.

betty and karen have been hired to paint the houses in a new development. working together, the women can paint a house in two-thirds the time that it takes karen working alone. betty takes 4 h to paint a house alone. how long does it take karen to paint a house working alone?
Betty takes 6 hours to paint a house alone, that indicates she can paint 1/6 of the house in 1 hour then Karen working alone will paint a house in 3 hours.
How long does it take paint a house working alone?Since Betty takes 6 hours to paint a house alone, that indicates she can paint 1/6 of the house in 1 hour.
Karen can even paint 1/x in 1 hour
Both of them will paint the house in 3/2 hours.
We then add them together which gives:
1/6 + 1/x = 3/2x
The lowest common multiple is 6x
1x/6x + 6/6x = 9/6x
We then leave out the denominators
1x + 6 = 9
simplifying the above equation, we get
x = 9 - 6
x = 3
Therefore, the value of x = 3.
Karen working alone will paint a house in 3 hours.

4. If M is the midpoint of line segment EF. E is located at (10,-8) and M is located at (-6, -2). Find the other
endpoint.
Answer:
The other endpoint is F( - 22, 4)=============================
GivenSegment EF with:
Endpoint E = (10, - 8),Midpoint M = (- 6, - 2),Endpoint F = (x, y).SolutionUse midpoint equation:
x = (x₁ + x₂)/2, y = (y₁ + y₂)/2Find unknown coordinates of the point F:
- 6 = (10 + x)/2 ⇒ -12 = 10 + x ⇒ x = - 12 - 10 = - 22,- 2 = (- 8 + y)/2 ⇒ - 4 = - 8 + y ⇒ y = - 4 + 8 = 4.So the point is F = ( - 22, 4)
Answer:
F = (-22, 4)
Step-by-step explanation:
Midpoint between two points
[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\\\\ \textsf{where $(x_1,y_1)$ and $(x_2,y_2)$ are the endpoints.}[/tex]
Given information:
Midpoint = (-6, -2)E = (10, -8)Define the endpoints of the line segment EF:
Let (x₁, y₁) = endpoint E = (10, -8)Let (x₂, y₂) = endpoint FSubstitute the given information into the formula:
[tex]\implies (x_M,y_M)=\left(\dfrac{x_F+x_E}{2},\dfrac{y_F+y_E}{2}\right)[/tex]
[tex]\implies (-6,-2)=\left(\dfrac{x_F+10}{2},\dfrac{y_F-8}{2}\right)[/tex]
Find the x-coordinate of M:
[tex]\implies \dfrac{x_F+10}{2}=-6[/tex]
[tex]\implies x_F+10=-12[/tex]
[tex]\implies x_F=-22[/tex]
Find the y-coordinate of M:
[tex]\implies \dfrac{y_F-8}{2}=-2[/tex]
[tex]\implies y_F-8=-4[/tex]
[tex]\implies y_F=4[/tex]
Therefore, the coordinates of endpoint F are (-22, 4).

devon has 15 dollars to spend on snacks. the corner store has candy bars for $1 and sports drinks for $3. he only wants to purchase at most 10 items.
Devon can have 6 candy bars and 3 sports drinks when he has $15 to spend.
According to the question,
We have the following information:
Devon has $15.
Cost of 1 candy bar = $1
Cost of 1 sports drink = $3
Devon wants to purchase at most 10 items.
It means that the total items should be less than or equal to 10.
Now, we have to spend $15 in such a way that number of items should be less than or equal to 10.
Now, we will look for the number of items for sports drink and change the number of candy bars accordingly.
Let's take 1 sports drink:
$3
We are left with $12. Now, there will be 12 candy bars.
So, this can not satisfy our conditions.
Let's take 2 sports drink:
$6
We are left $9. Now, there will be 9 candy bars. And the number of items is 11.
(This is not satisfying our condition.)
Let's take 3 sports drink:
$9
We are left with $6. Now, there will be 6 candy bars. And the number of items is 9.
This is satisfying all the conditions.
Hence, Devon can have 6 candy bars and 3 sports drinks when he has $15 to spend on snacks.

For which value of x does the graph of the following function F(x) have a
vertical asymptote?
F(x) =
1
X-11
Answer:
x = 1
Step-by-step explanation:
Horizontal asymptotes are the y-values for which a particular function is undefined;
Finding the horizontal asymptote for linear reciprocal function is quite simple;
For this kind of function, where there is no x term in the numerator, the horizontal asymptote is just equivalent to the constant added to the fraction (note: having no added constant is the same as having an added 0);
so:
f(x) = 1/(x - 1) = (1/( - 1 )) + 0
The horizontal asymptote is y = 0 for this function.
If it was F(x) = (1/(x - 1)) + 1, the horizontal asymptote would be y = 1

(1) 65+......=180
(2) 11x+.......=180
(3) 11x=.........
(4) x=........
To solve this question we have to use some theorem.
Firstly solving the first question.
As we know that the angle of straight line is 180[tex]^o.[/tex]
So from the diagram
[tex]65+z=180^o[/tex]
Subtract 65 on both side
[tex]65+z-65=180^o-65[/tex]
[tex]z=115[/tex]
Hence, 65+[tex]\underline{115}[/tex]=180.
Now finding the value of second question.
Using Alternate Exterior Angles Theorem
According to theorem the angle beside 11x - 17 is 65.
As we know that the angle of straight line is 180[tex]^o.[/tex]
So 11x-17+65=180[tex]^o.[/tex]
Simplifying
So [tex]11x+\underline{48}=180^o[/tex]
Now finding the value of third question.
From the second question answer we get [tex]11x+{48}=180^o[/tex]
Now solving this equation to find the value of 11x
Subtract 48 on both side
[tex]11x+{48}-48=180^o-48[/tex]
[tex]11x=132[/tex]
Hence, [tex]11x=\underline{132}[/tex]
Now solving the fourth question.
To find the value of fourth question we further simplify the answer of third question.
[tex]11x=132[/tex]
Divide by 11 on both side
[tex]\frac{11}{11}x=\frac{132}{11}[/tex]
[tex]x=12[/tex]
Hence, [tex]x=\underline{12}[/tex]
