Hi
3*5000 +X*2500 = 25 000
15 000 + 2 500X = 25 000
2 500X = 25 000 - 15 000
2 500 X = 10 000
x = 10 000 / 2 500
X = 100/25
X = 4
You need 4 post for B
3*5000 + 4* 2 500 = 15 000 + 10 000 = 25 000

An airport offers 2 shuttles that run on different schedules. If both shuttles leave the airport at 4.00 pm at what time will they leave the airport together
Answer:
4:18 pm
Step-by-step explanation:
An airport offers 2 shuttles that run on different schedules.If both shuttles leave the airport at 4:00 p.m.,at what time will they next leave theairport together.
Shuttle A leaves every 6 minutes
Shuttle B leaves every 9 minutes
Solution
To solve for when next both shuttles will leave the airport together, find the least common multiples of 6 minutes and 9 minutes
Shuttle A (every 6 minutes) = 6, 12, 18, 24
Shuttle B (every 9 minutes) = 9, 18, 27, 36
The least common multiples of 6 minutes and 9 minutes is 18 minutes
4:00 pm + 18 minutes
= 4:18 pm
The next time both shuttles will leave theairport together is 4:18 pm of the same day

scale, in degrees, and C, the temperature
measured on the Celsius scale, also in
degrees. What is the temperature in
degrees Celsius when the temperature in
degrees Delisle is 78°?
BO
Answer:33
Step-by-step explanation:
3/2 —> 1.5
1.5(100-C) C is 78°
1.5(100-78)
1.5(22)
33
The temperature in degrees Celsius, if the function of the relationship is given as 78 = 3/2(100 - C), is calculated as: C = 48
What is Function?A function is a form of equation that relates one quantity that changes with another.
Given the formula for the function representing the relationship between D and C as, D = 3/2(100 - C), to find the temperature in degrees Celsius when the D = 78, substitute D = 78 into D = 3/2(100 - C).
78 = 3/2(100 - C)
(2)(78) = 3(100 - C)
156 = 3(100 - C)
156/3 = 100 - C
52 = 100 - C
52 - 100 = -C
-48 = -C
C = 48

Rafiq compares the
expressions 4 X 8 and 8 X 12. He says that 8 is twice
as much as 4, so 4 X 8 must be twice as much as 8 X 12.
Correct his statement, and explain his error.
HELLLPPPPP
Answer:
Hey there!
Rafiq's error was that the other number is also changing. He had 4 x 8 and if he had 8 x 8, that would be twice as much, but he used 8 x 12 instead, and 12 is not 8.
Let me know if this helps :)
The other number that was also changing was Rafiq's mistake if Rafiq compares the expressions 4x8 and 8x12.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that are +, -, ×, and ÷.
It is given that:
Rafiq compares the expressions 4x8 and 8x12
The correct statement is for Rafiq compare the expressions 4 X 8 and 8 X 12
The fact that the other number was also changing was Rafiq's mistake.
Rafiq had 4 × 8, therefore 8 x 8 would have been twice as much; however, he utilized 8 x 12, even though 12 is not equal to 8.
Thus, the other number was also changing was Rafiq's mistake if Rafiq compares the expressions 4x8 and 8x12.

Does anyone know the answer
Answer:
Both angles B and C are equal to 40°
Step-by-step explanation:
The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.
[tex]2x+10=3x-5\\10=x-5\\15=x[/tex]
Now we are going to plug x back into each expression to solve for angles B and C.
Angle B
[tex]2x+10[/tex] ⇒ [tex]2(15)+10=40[/tex]
Angle C
[tex]3x-5[/tex] ⇒ [tex]3(15)-5=40[/tex]
Both angles B and C are equal to 40°
Rachel has 24 red candies and Maya has 18 green candies. They want to arrange the candies in such a way that each row contains equal number of candies and also each row should have only red candies or green candies. What is the greatest number of candies that can be arranged in each row?
Answer: 6 candies per row.
Step-by-step explanation:
The restrictions that we have are:
Each row has the same number of candies.
Each row has only one color of candy.
We want to find the largest possible rows.
We have 18 green candies and 24 red candies.
Now, to arrange them in rows of equal numbers, we should find a common factor between 18 and 24. (particularly, we want to find the largest common factor between 18 and 24).
Now, to find common factors we first take the smaller number, and we divide it by different numbers, starting by 2 (we want to divide by small numbers, so the result will be the largest factor)
18/2 = 9.
Now to see if 9 is also a factor of 24, we see if the quotient between 24 and 9 is a whole number.
24/9 = 2.66
This is not a whole number, so 9 is not a common factor.
Now we divide by the next number, 3.
18/3 = 6.
24/6 = 4.
So 6 is a common factor of 18 and 24.
Then each row will have 6 candy.
And we will have:
18/6 = 3 rows of green candy.
24/ = 4 rows of red candy.
which is not a rational

A student has some $1 and $5 bills in his wallet. He has a total of 19 bills and that are worth $55. how many of each type of bill does he have
Answer:
y= 9 ( 5 dollars bill)
x=10 ( one dollar bill)
Step-by-step explanation:
let x be the one dollar bill and y the 5 dollar bill
x+y=19 ⇒ x=19-y
x+5y=55 ( solve by substitute x=19-y)
19-y+5y=55
4y=55-19
4y=36 ⇒ y=36/4
y= 9 ( 5 dollars bill)
x+y=19
x+9=19
x=19-9
x=10 ( one dollar bill)
check :
x+5y=55
10+5(9)=
10+45 = 55 dollars

Pa = 3x-4. Pr = pa+ar
Ar = 7
3x-4+7= 21
Combine light terms
Then order of operations
3x-3=21
3x-18
X=6
The required value of x is 6
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign =.
Now it is given that,
PA = 3x-4
PR = 21 meters
AR=7 meters
Since point A is between point R and point P.
Thus we can write,
PR = PA + AR
Put the values of PA,PR and AR we get,
21 = 3x - 4 + 7
Subtracting 7 both the side we get,
3x - 4 = 14
Adding 4 both the side we get,
3x = 18
Dividing both side by 3 we get,
x = 6
which is the required value of x.
Thus, the required value of x is 6.

The question is not clearly stated, below is the clearly stated question and answer:
A customer wants you to enlarge a photo to 2 3/4 its current height. The photo’s current height is 3 1/4 inches. What should its enlarged height be, in inches?
Answer:
[tex]Enlarged\ height = 8\frac{15}{16}\ inches[/tex]
Step-by-step explanation:
[tex]current\ height\ =\ 3\frac{1}{4} = \frac{13}{4} \\ magnification\ factor = 2\frac{3}{4} = \frac{11}{4} \\Magnification (enlargement)\ =\ (magnification\ factor) \times (current\ height)\\Magnification\ =\ \frac{11}{4} \times \frac{13}{4}\\ Magnification\ =\ \frac{143}{16}[/tex]
Next, we will concert from the improper fraction to a mixed fraction:
when 143 is divided by 16, there will be 8 whole numbers and a remainder of 15, hence, the mixed fraction is:
[tex]\frac{143}{16} = 8\frac{15}{16}[/tex] (Alternatively, a scientific calculator can be used)
Therefore, enlarged height [tex]= 8\frac{15}{16}\ inches[/tex]
In the diagram JL = 120, What are JK and KL? Explain how you found your answer.
Answer:
JK = 42
KL = 78
Step-by-step explanation:
To find the lengths of JK and KL, we need to first find the value of x. We know that the length of the entire line is 120. That means we need to add the lengths of JK and JL and set it equal to 120.
4x+6+7x+15 = 120
Combine like terms.
11x+21 =120
Subtract 21 from each side.
11x= 99
Divide both sides by 11.
x=9
Now that we know the value of x, we simply plug it into the equations to find out the lengths of each line segment.
JK = 4x+6
4(9)+6 (x is plugged in)
36+6 = 42
JK=42
Now lets do KL.
7x+15
7(9)+15
63+15 = 78
KL = 78
The values of JK = 42 and KL= 78.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment JL , where the length of line segment JL refers to the distance between its endpoints, J and L.
Given that JL = 120,
And JK = 4x + 6 and KL= 7x + 15
J_________K______________L
⇒ JL = JK + KL
⇒ 120 = 4x + 6 + 7x + 15
⇒ 120 = 11x + 21
⇒ 11x = 99
⇒ x = 9
Substitute the values of x = 9 in the JK = 4x + 6 and KL= 7x + 15,
JK = 4(9) + 6 = 42
KL= 7(9) + 15 = 78
Hence, the values of JK = 42 and KL= 78 .

Answer:
Para preparar la receta de flan para 9 personas se necesita [tex]\frac{3}{4}[/tex] L de leche
Step-by-step explanation:
La regla de tres simple directa se utiliza cuando el problema trata de dos magnitudes directamente proporcionales, es decir, magnitudes que si al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida por ese número. Es decir, cuando una magnitud aumenta la otra también lo hace en la misma proporción, y si la magnitud disminuye la otra disminuirá de igual forma.
Conociendo 3 valores “a”, “b” y “c” y teniendo un valor incógnita que deseamos conocer, la regla de tres simple directa se aplica de la siguiente forma:
a ⇒ b
c ⇒ x
Entonces : [tex]x=\frac{c*b}{a}[/tex]
En este caso se aplica de la siguiente manera: considerando que cada persona recibe una porción, si para preparar la receta para 3 personas se necesita [tex]\frac{1}{4}[/tex] de litros de leche, para preparar la receta para 9 personas cuánta leche se necesita?
3 personas ⇒ [tex]\frac{1}{4}[/tex] L
