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

Answers

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:

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

X=2 !!!!!!!!!!!!!!!!!!!!

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

Answers

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.

Which value for b makes the equation b/4 =12 true?

Answers

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.
