Divide $27,000 into 3 parts so that the second part is three times the first and the
third part is twice the second.
Justify why the sum of 3a and
2b cannot be represented as 5ab.
Answer:
You cannot add two numbers that have different variables.
Step-by-step explanation:
You can multiply them, but since 3 is multiplied by "a" or a different number than "b" then the answer would be incorrect.
Answer:
because 3a and 3b have different variables. You can't add "unlike terms" to each other because the variables have different values. by writing 3a+2b as 5ab, you're completely changing the meaning of the problem. You would get a totally different answer than you would by just adding the two terms together.

The formula to convert from Celsius to Fahrenheit is
F=95C+32 . Use this formula to complete the statements below. Round your answers to the nearest tenth as needed.
If the temperature is 78 degrees Fahrenheit , that is equivalent to
degrees Celsius.
If the temperature is 41 degrees Celsius, that is equivalent to
degrees Fahrenheit.
The temperature in Celsius will be 25.5556 °C and he temperature in degree Fahrenheit will be 105.8 °F, respectively.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function to convert temperature from Celsius to Fahrenheit is F=(9/5)C+32.
A.) Given that If the temperature is 78 degrees Fahrenheit. Therefore, the temperature in degree Celsius will be,
F = (9/5)C + 32
78 = (9/5)C + 32
78 - 32 = (9/5)C
46 = (9/5)C
C = (46 × 5)/9
C = 25.5556
Hence, the temperature in Celsius will be 25.5556 °C.
B.) Given that the temperature is 41 degrees Celsius. Therefore, the temperature in degree Celsius will be,
F = (9/5)C + 32
F = (9/5)41 + 32
F = 73.8 + 32
F = 105.8
Hence, the temperature in degree Fahrenheit will be 105.8 °F.

A ticket service is selling tickets to a concert. An order of 4 tickets has a price of $63 and an order
of 6 tickets has a price of $92. Write an equation to find the price of any amount of tickets.
Answer:
y = 14.5x + 5
Step-by-step explanation:
x = Number of tickets for the concert
y = Price of the order of x tickets
y = 14.5x + 5
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Order of 4 tickets has a price of $63
Order of 6 tickets has a price of $92
2. Write an equation to find the price of any amount of tickets.
Let's find out the price of a ticket to understand if there's a service fee and how much is it, this way:
Price of a ticket = (Order of 6 tickets - Order of 4 tickets)/2
Price of a ticket = (92 - 63)/2
Price of a ticket = 29/2 = 14.50
If a ticket costs $ 14.50, 4 tickets will cost $ 58 and 6 tickets will cost $ 87, therefore there is a service or delivery fee of $ 5.
Order of 4 tickets - Price of 4 tickets = Service or delivery fee
Replacing, we have:
63 - 58 = 5
Order of 6 tickets - Price of 6 tickets = Service or delivery fee
Replacing, we have:
92 - 87 = 5
Now, we can write the equation to find the price of an order of any amount of tickets, this way:
x = Number of tickets for the concert
y = Price of the order of x tickets
y = 14.5x + 5

In the figure, the angle x° is an alternate angle with angle 54° so the measure of angle x° is 54°.
We have,
From the figure,
Line m and line n are parallel.
Line t is the transversal line.
Now,
Alternate angles are a pair of angles that are formed when a transversal (a line that crosses two other lines) intersects two parallel lines.
When this happens, the alternate angles are on opposite sides of the transversal and are congruent, which means they have the same measure.
Angle 54° and angle x° are alternate angles.
Alternate angles are equal.
So,
x° = 54°
Thus,
The measure of angle x° in the figure is 54°.

PLEASE HELPPPPPP. I NEED IT DONEEEEE.
Answer:
1. Couples tickets: $8
Individual tickets: $4
2. Song download cost: $2
Movie download cost: $15
Step-by-step explanation:
You can solve both of these questions by doing system of equations.
Let's start with question 1.
There are 2 variables in this equation:
- Couples tickets price: let's represent these with the letter C
- Individual tickets price: let's represent these with the letter K
Writing the two equations would look this these:
5c + 2k = 48
3c + 2k = 32
Next, isolate a variable. I am going to isolate K in the first equation.
[tex]2k = -5c + 48 \\k = -\frac{5}{2}c + 24[/tex]
Now that we isolated a variable we can plug that back in to the second equation:
[tex]3c + 2(-\frac{5}{2}c + 24) = 32\\3c - \frac{10}{2}c + 48 = 32\\3c -5c + 48 = 32\\-2c + 48 = 32\\-2c = -16\\c = 8[/tex]
We found that c is equal to 8 so we can put that back in to an equation to solve for k.
5(8) + 2k = 48
40 + 2k = 48
2k = 8
k = 4
Therefore, the price for couples tickets is $8 and the price for individual tickets is $4.
Check #1:
5(8) + 2(4) = 48
40 + 8 = 48
48 = 48
3(8) + 2(4) = 32
24 + 8 = 32
32 + 32
Now, let's go on to question 2.
There are 2 variables in this equation:
- Price of songs downloaded: let's represent these with S
- Price of movies downloaded: let's represent these with M
Writing the two equations would look like this:
15s + 11m = 195
15s + 8m = 150
There is a simple way to answer this system, however.
If you change the bottom equations signs to negative you can minus the second equation from the first equation like this:
15s + 11m = 195
-(15s +8m = 150)
Minus them to get this equation:
3m = 45
Solve
m = 15
We have found that each movie download costs $15, now let's plug this back into an equation:
15s + 11(15) = 195
15s + 165 = 195
15s = 30
s = 2
Each song costs $2 to download.
Check #2:
15(2) + 11(15) = 195
30 + 165 = 195
195 = 195
15(2) + 8(15) = 150
30 + 120 = 150
150 = 150

(5 points) Group of answer choices x + 4y ≥ 15; y ≥ 0 x − 4y ≥ 15; y ≥ 0 x + 4y ≤ 15; y ≥ 0 −x − 4y ≥ 15; y ≥ 0
Answer:
x + 4y ≥ 15; y ≥ 0
Step-by-step explanation:
The solid line signifies it is a ≤ or ≥.
The equation of the line joining 0, 3.75 and 15, 0 is gotten using the formula:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\Substituting:\\\\y-3.75=\frac{0-3.75}{15-0}(x-0)\\\\ y-3.75=-\frac{1}{4}x\\\\y=-\frac{1}{4}x+3.75\\\\4y=-x+15\\\\4y+x=15[/tex]
Since the first and second quadrant are shaded, this represents y ≥ 0.
Also, above the solid line of 4y + x = 15 is shaded, this represents 4y + x ≥ 15.
Hence the inequality modeled is x + 4y ≥ 15; y ≥ 0

The altitude is 9 m is opposite
and, horizontal line is adjacent.
Formula is:
Sin θ = opposite / hypotenuse
where Sinθ = 32 degree
opposite = 9 m
Hypotenuse = x m
Hence, Sin 32 = 9/x
x = 9/ sin 32 , and Sin 32 degree = 0.5299(approx.)
x = 9/ 0.5299
x = 16. 984 (approx.)
