Answer:
k = 54/79
Step-by-step explanation:
You can eliminate fractions by multiplying both sides by 12.
15(2 -k) = 24(3k -1) -8k
30 -15k = 72k -24 -8k
54 = 79k
54/79 = k

The ratio of red marbles to blue marbles in a bag is 2 to 3. Which of the following could be
the number of red and blue marbles in the bag?
O 4 red marbles and 6 blue marbles
O 4 red marbles and 5 blue marbles
O 6 red marbles and 8 blue marbles
Answer:
4 red marbles and 6 blue marbles is the correct answwer
Step-by-step explanation:
Answer:
A.) 4 red marbles and 6 blue marbles
Step-by-step explanation:
If you times 2 x 2 then you will get 4
If you times 3 x 2 then you will get 6
And since the ratio is red : blue
2 : 3 is equivalent to 4 : 6
Just like [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.
if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:
A construction worker fills a mold with concrete. This solid figure represents the mold.
What is the volume of the concrete that fills the mold?
Answer:
volume = 338 x 20 = 6760 cm^3
Step-by-step explanation:
large rectangular top area = 14 x 22 = 308 cm^2
small rectangular top area = 6x5 = 30 cm^2
total top area = 308 + 30 = 338 cm^2
volume = 338 x 20 = 6760 cm^3
Find each difference.

Plsss can someone answer I have 2 minutes
Answer:
x = 2
Step-by-step explanation:
You can make a ratio out of this!
2 / x = (x+1) / 3
1. Cross multiply^
2. 2 * 3 = x (x+1)
3. 6 = x^2 + x
3. x^2 + x - 6
4. Factor^
5. (x-2)(x+3)
6. x - 2 = 0 turns into x = 2
7. x + 3 = 0 turns into x = -3
8. There's not way to measure -3 yet, so you are left with x = 2

If triangle RST cong triangle XYZ , then ST is congruent to which of the following?
Which value for b makes the equation b/4 =12 true?
48 would be in that place because 12 x 4 would get you to 48, which means that 48 is the answer for this one. Hope this helped. I had to edit the answer out because it glitched, sorry :/
The value for b that makes the equation b/4 = 12 true is b = 48.
We have to find the value for b that makes the equation b/4 = 12 true, we can solve for b by multiplying both sides of the equation by 4.
b is the variable in the equation.
b/4 = 12
Multiply both sides by 4:
4 × (b/4) = 4 × 12
This simplifies to:
b = 48
Therefore, the value for b that makes the equation b/4 = 12 true is b = 48.

An artist spent $75 on supplies to create paintings. Each painting the artist created was sold for $25. Which function can be used to find p, the profit when c paintings are sold?
Answer:
Step-by-step explanation:
The function can be used to find p, the profit when c paintings are sold is p = 25x - c.
Given that, an artist spent $75 on supplies to create paintings.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Let the x be the number of paintings sold.
Now selling price of articles = $25x
Profit (p) = 25x - c
Hence, the function can be used to find p, the profit when c paintings are sold is p = 25x - c.

You buy a flight to California for $305.72. The tax is 7.65%. What is the final cost of the ticket?
Show work and use method
Answer:309.83
Step-by-step explanation:
The final cost of the flight ticket $329.10758.
Given that, the cost of flight ticket is $305.72 and tax=7.65%.
What is the tax?Taxes are mandatory contributions levied on individuals or corporations by a government entity—whether local, regional, or national. Tax revenues finance government activities, including public works and services such as roads and schools, or programs such as Social Security and Medicare.
Now, tax = 7.65% of 305.72
= 7.65/100 × 305.72
=0.0765 × 305.72
=$23.38758
Total cost = 305.72+23.38758
=$329.10758
Therefore, the final cost of the flight ticket $329.10758.
