The ratio of cats to dogs in the park is 2:3. If there are 18 dogs in the park, how many cats are in the park?

Answer:

it would be x=-4

hope i helped ya

Answer:

x = -4

Step-by-step explanation:

3x -2(6-x) = 7x +2(5+x) -6

Distribute -2 through the parentheses 3x -12 +2x = 7x +2(5+x) -6

Distribute 2 through the parentheses 3x -12 +2x = 7x +10 +2x -6

3x -12 +2x = 7x +10 +2x -6 cancel equal terms on both sides of the equation

3x -12 = 7x +10 -6 subtract the numbers 3x -12 = 7x +4

                           Move variable to the left left handed side and change its sign

3x -7x-12 = 4   -->   3x -7x = 4 + 12  -->  -4x = 4+12  --> -4x = 16

             Divide both sides of the equation by -4  -->  x = -4

Ammount amy earns if she sells 33 books: 88 dollars

Step-by-step explanation:

they let us know that she earns 55 dollars a week. this is the minimum she can earn in a week. So 55 is just 55. she cant earn more or less than 55 a week by just working there. the variable is the ammount of books she sells every week. Every book she sells gives her an extra one dollar to her overall wage per week. so 55 is the base and the one dollar per book is the variable that changes depending on how much she sold. So the equation would the base of 55 and the variable 1x (x being the ammount of books being sold and the 1 being how much money she makes from each book) and now just put them together with a plus sign and it would look like this

55 + 1x = ...

If she was to sell 33 books and shes earning 1 dollar per book 1(33), we only change the x from x to 33

55 + 1(33) which gives us 88

Answer/Step-by-step explanation:

well, first figure out how many units/times prism A was enlarged to become prism B...

16 ÷ 2 = 8

Now if we apply that info to the length of the prism, then...

80 ÷ 8 = 10

Therefore x = 10

And the Prisms remain congruent and proportional!

Answer:

x = g + c

Step-by-step explanation:

This is the answer because:

1) Solve for  x  by simplifying both sides of the equation, then isolating the variable.

Therefore, the answer is x = g + c

The correct answer is C. The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground.

Explanation:

Two key features of living organisms are energy processing and response to stimuli. These two features imply organisms require nutrients, which can be taken from the environment or created through a process such as photosynthesis and they sense their surroundings and respond to it.

Moreover, these two features are exemplified by mushroom (fungi) in the sentence "The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground" because the first section shows the developing mushroom takes nutrients from the soil or its environment and this is essential for growing and survival. Also, the second section of the sentence shows the developing mushroom can sense its environment and respond by developing only in appropriate conditions.

C

Answer:

P(Non-Spam/Spam Detected) = 5/99

Step-by-step explanation:

To determine the probability that it is in fact a non-spam email, we will employ the use of Bayes Theorem: P(A/B) = (P(B/A) x P(A)) / P(B).

P(Spam) = P(Non-Spam) = 0.5  

P(Spam Detected) = P(Spam) * rate of detection = 0.5 * 0.99

P(Detected/Non-Spam) = P(false positives) = 0.05

Using Bayes Theorem, P(Non-Spam/Spam Detected) = ( P(Spam Detected/Non-Spam) x P(Non-Spam) ) / P(Spam Detected)

= 0.05*0.5 / 0.5*0.99

= 5/99

Using conditional probability, it is found that there is a 0.0481 = 4.81% probability that it is in fact a non-spam email.

Conditional Probability

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

In this problem:

The percentages of emails detected as spam are:

Hence:

[tex]P(A) = 0.5(0.99) + 0.5(0.05) = 0.52[/tex]

The probability of an email being detected as spam and not being spam is:

[tex]P(A \cap B) = 0.5(0.05)[/tex]

Hence, the conditional probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.5(0.05)}{0.52} = 0.0481[/tex]

0.0481 = 4.81% probability that it is in fact a non-spam email.

Answer:

a) 6x³ − 5x² − 39x + 35

b) no

Step-by-step explanation:

(2x − 5) (3x² + 5x − 7)

Distribute:

3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)

Distribute again:

6x³ − 15x² + 10x² − 25x − 14x + 35

Combine like terms:

6x³ − 5x² − 39x + 35

5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).

Answer:

The answer is 5.75

Step-by-step explanation:

I used desmos

Steps to solve:

-4(x - 2) + 5 = -10

~Distribute left side

-4x + 8 + 5 = -10

~Combine like terms

-4x + 13 = -10

~Subtract 13 to both sides

-4x = -23

~Divide -4 to both sides

x = 23/4
