x = 25/2
this is your answer
Step 1. Simplify x + 4x + 43 to 5x + 43
5x + 2(x + 9) = 5x + 43
Step 2. Cancel 5x on both sides
2(x + 9) = 43
Step 3. Divide both side by 2
x + 9 = 43/2
Step 4. Subtract 9 from both sides
x = 43/2 - 9
Step 5. Simplify 43/2 - 9 to 25/2
x = 25/2

two people begin traveling at the same time from opposite ends of a 20 mile trail. one person travels 3 miles per hour faster than the other. if they meet after 2 hours, what are the rates of the 2 people
Let us assume rate of other person = x miles per hour.
Rate of first person is 3 miles per hours faster than other.
Therefore, rate of first person = (x+3) miles per hour.
Total distance between them = 20 miles.
And total time taken by them is 2 hours.
We know, distance, time and rate relation:
Distance = Rate × Time.
Therefore, distance covered by other person = x * 2 = 2x.
Distnace covered by first person = (x+3)*2.
Total distance covered by both = 20 miles.
We can setup an equation
Total distance covered by both = Distnace covered by first person + distance covered by other person.
2(x+3) +2x = 20.
Now, we can solve the eqation for x.
2x +6 +2x = 20.
4x +6 =20.
Subtracting 6 from both sides, we get
4x +6-6 =20-6
4x = 14.
Dividing both sides by 4, we get
x=3.5
Rate of first person = (x+3) = 3.5+3 = 6.5 miles per hour.
Therefore, the rate of first person is 6.5 miles per hour and rate of second person 3.5 miles per hour.shannon walked 4 and 7/8 miles and ran 3 1/2 miles during the week. how much further did she walk than run

Someone Explain to me how 5. Is valid ???
This is valid through the law of syllogism. If you swap lines 1 and 2, then you'll have this argument:
If I step on a beehive, then I will get stung.
If I get stung by a bee, then it will hurt.
Therefore, if I step on a beehive, then it will hurt
------------------
So it's like connecting a chain together. Point A (stepping on the hive), leads to point B (getting stung), which leads to point C (getting hurt). We can take a shortcut to bypass point B to jump from A to C in one step. Check out the attached image for a visual of what I'm referring to.
evaluate f(x) when x = 6
when x = 6, you have to use the top equation .... because -6 < 6 < 9
f(x) = 6x² + 2
f(6) = 6(6)² + 2
= 6(36) + 2
= 216 + 2
= 218
Answer: D
Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
[tex]f(x)=6x^2+2,-6<x<9\\\\f(x)=12,9\leq x<13[/tex]
We need to find the value of f(x) when x = 6.
As we can see that x = 6 is lie in the interval -6<x<9.
So, f(x) would be [tex]6x^2+2[/tex]
So, value of f(x) at x = 6 would be
[tex]f(x)=6(6)^2+2=216+2=218[/tex]
Hence, fourth option is correct.
Solve for x.

Lauren’s bedroom measures 21 feet by 14 feet, with a closet that measures 3 feet by 6 feet. If carpet costs $4.25 per square foot, how much will it cost to carpet Lauren’s room & closet?
Lauren will need $1326 to cover 312 ft^2 of her room with carpet.
Final answer:
To carpet Lauren's room and closet, calculate the area of both then multiply by the carpet cost per square foot, resulting in a total cost of $1,326.
Explanation:
To calculate the cost of carpeting Lauren's room including the closet, we first need to find out the total area that needs to be carpeted. The area of Lauren's room is found by multiplying the length by the width: 21 feet × 14 feet, which equals 294 square feet. Similarly, the area of the closet is 3 feet × 6 feet, which equals 18 square feet.
To find the total area to be carpeted, we add the area of the room to the area of the closet: 294 square feet + 18 square feet equals 312 square feet. The cost to carpet this total area is then calculated by multiplying the total area by the cost per square foot: 312 square feet × $4.25 per square foot, which equals $1,326.
Therefore, to carpet both Lauren's room and the closet, it will cost $1,326.

Well first you find the common denominatior of 1/7 and 4/9 which is 63 so then you see how many times does 7 go into 63 so this is part where you multiply 7 and 9 which gives you 63 and then you do how many times 9 go into 63 which is 7 so then you will take 7 times the 4 which is 28 so now your fractions should be 9/63 and 28/63 then now your next step is to add the 9 and 28 which is now 37/63 and you ask yourself and you divide that by any number to get a smaller number which is no so that is your answer
what is the opposite integer of-11
Answer: 11
Step-by-step explanation: Think of the opposite of an integer in terms of a number line. The opposite of an integer is the same distance from zero as the original integer but on the opposite side of zero.
On the number line, we can see that -11 is 11 units to the left of zero, so its opposite will be 11 units to the right of zero.
So the opposite of -11 is +11.
I have also attached my work in the image provided.
Final answer:
The opposite integer of -11 is 11. An opposite integer is simply the number with the opposite sign, and the opposite of a negative number is the same number but positive.
Explanation:
The opposite integer of -11 is 11. The opposite integer is simply the number with the opposite sign, so for any negative integer, the opposite is the same number but positive. Similarly, if you have a positive integer, its opposite would be negative. For example, the opposite of 5 is -5. To find the opposite, you change the sign of the number without changing its absolute value or magnitude. This is similar to finding the additive inverse of a number, which is what is added to the original number to result in zero. So, in the case of -11, adding 11 would give you zero: -11 + 11 = 0.

Twice the difference of a number and six is negative six, find the number
Let x = a number
3(6 - x) = -9
Divide both sides of equation by 3.
6 - x = -3
Subtract 6 on both sides of equation.
-x = -9
Divide both sides of equation by -1.
x = 9
The number is 9.
The difference between a number and six is [tex] x-6 [/tex]. Twice this difference is [tex] 2(x-6) [/tex]. If you want this difference to be negative, six, you have
[tex] 2(x-6)=-6 [/tex]
Divide both sides by 2:
[tex] x-6 = -3 [/tex]
Add 6 to both sides:
[tex] x = 3 [/tex]
Ronnie had a certain number of movies, m. One-fourth of those movies were action movies. He sold nine action movies to reach a grand total of four action movies. What was the original number of movies Ronnie had?
A. 52
B. 48
C. 26
D. 39
By adding the action movies Ronnie sold to the ones he kept, we determined he had 13 action movies, which was one-fourth of his total. Multiplying 13 by four revealed that he originally had 52 movies in total.
Explanation:The student's question pertains to finding the original number of movies Ronnie had given that one-fourth of those movies were action movies, and after selling nine of them, he was left with four action movies. To find the original number of action movies he had, we can add the four action movies he has left to the nine action movies he sold. This gives us a total of 13 action movies.
Since these 13 action movies represented one-fourth of his original collection, we multiply 13 by four to find the total number of movies Ronnie originally had. Therefore, Ronnie's original number of movies was 13 imes 4 = 52.

erica paid $753.95 for dance classes. She paid $123.95 registration fee and $45 for each week. What is w,the number of weeks erica was enrolled in dance classes?
Erica was enrolled in dance classes for 14 weeks, as determined by subtracting the registration fee from the total amount paid and dividing by the weekly fee.
Explanation:Erica paid a total of 753.95 for dance classes, which included a $123.95 registration fee and a weekly fee of 45. To find out the number of weeks w Erica was enrolled in dance classes, we need to subtract the registration fee from the total amount and then divide the remainder by the weekly fee.
The equation to represent this situation is:
w = (Total amount paid - Registration fee) / Weekly fee
Plugging in the values, we get:
w = (753.95 - 123.95) / 45
Calculating the difference and then dividing by the weekly fee:
w = 630 / 45
So:
w = 14
Erica was enrolled in dance classes for 14 weeks.
The number of weeks Erica was enrolled in dance classes, w, is 14 weeks.
We need to subtract the registration fee from the total amount paid and then divide the remaining amount by the weekly fee.
First, we identify the total amount paid for the dance classes, which is $753.95. This includes the registration fee and the weekly fees for the classes.
Next, we identify the registration fee, which is $123.95.
The weekly fee for the dance classes is $45.
The total amount paid, excluding the registration fee, is the total cost minus the registration fee:
[tex]\[ \text{Total amount paid excluding registration} = \$753.95 - \$123.95 \][/tex]
[tex]\[ \text{Total amount paid excluding registration} = \$630.00 \][/tex]
Now, we divide this amount by the weekly fee to find the number of weeks Erica was enrolled:
[tex]\[ w = \frac{\$630.00}{\$45} \][/tex]
[tex]\[ w = 14 \][/tex]
Leena knits 10 rows in 12 min. At this pace, how long will it take her to knit the next 25 rows?
10 rows= 12 mins
there's 25 rows in all so break it down into 10, 10, and 5 to make it more simple
12+12= 24 minutes for 20 rows
since you only have 5 rows left (which is half of ten), you divide the 12 by two as well.
12mins/2= 6 minutes for 5 rows
24mins+6mins= 30 minutes
answer: It will take 30 minutes to knit 25 rows
Answer:
62.5 minutes
Step-by-step explanation:

Which of the following best describes the movement of an object
Point A is located at (0, 4), and point B is located at (−2, −3). Find the point that is 1 over 4 the distance from point A to point B.
(-1, 0.75)
(-0.75, 2)
(-0.5, 2.25)
(-0.25, 3)
The answer is (-0.5, 2.25).
Explanation:
A = (0,4)
B = (-2,-3)
The line joining the two points from A to B can be represented as a vector:
r (x) = A + x*(B - A) , where 0<= x <= 1
Now, r (x) can be written as:
r (x) = (0,4) + x[ (-2,-3) - (0,4) ] = (0,4) + x (-2,-7)
Assuming x to be 1/4 (given)
x(1/4) = (0,4) + 1/4* (-2,-7) = (0 -1/2, 4 -7/4) = (-1/2, 9/4)
= (−0.5, 2.25)
Solution
Find the mid point of A and B.
The mid point of A and B is (-1. 0.5)
Now find mid point of (0, 4) and (-1, 0.5)
= [(0 + (-1)/2 , (4 +0.5)/2 ]
= (-1/2, 4.5/2)
= (-0.5, 2.25)
The answer is (-0.5, 2.25)

how many times is each basic property of associative commutative and distributive used to evaluate the expression 23 + 5x + 7y - x - 5 - 27 respectively
In evaluating the expression 23 + 5x + 7y - x - 5 - 27, the commutative property is used twice to rearrange terms, while the associative and distributive properties are not used.
Explanation:The student has asked how many times each basic property of associativity, commutativity, and distributivity is used to evaluate the expression 23 + 5x + 7y - x - 5 - 27. We can look at the expression and apply these properties to simplify it.
First, we'll combine like terms using the commutative property which states x + y = y + x and xy = yx. This allows us to rearrange terms:
Associative property: This property is not explicitly needed here since it involves the grouping of numbers, and this expression does not have parentheses to signify grouping for addition or multiplication.Commutative property: We use the commutative property twice to rearrange the x terms and the constant terms.Distributive property: This property is not used in this expression because there is no multiplication distributing over addition or subtraction.After rearranging, we get 23 - 5 + (5x - x) + 7y - 27. Now, simplifying the constants and combining the x terms, we have (23 - 5 - 27) + (5x - x) + 7y, which further simplifies to -9 + 4x + 7y.
Therefore, the commutative property was used twice in this simplification process, while the associative and distributive properties were not used.
