Answer:

y = 24

Step-by-step explanation:

5/4y-18=y/2

Multiply by 4 on all sides to get rid of the fractions

4(5/4y-18)=4*y/2

5y - 72 =2y

Subtract 5y from each side

5y-5y - 72 =2y-5y

-72 = -3y

Divide by -3

-72/-3 = -3y/-3

24 =y

A sequence is defined recursively by the formula f(n 1) = f(n) 3 . the first term of the sequence is –4. what is the next term i
ch4aika [34]

The sequence whose <em>first</em> term is - 4 and defined recursively by the formula f(n + 1) = f(n) + 3 have the element - 1 as the <em>next</em> term. (Correct choice: B)

<h3>How to determine an element of a sequence</h3>

In mathematics, sequences are sets whose elements observe at least a condition, which is represented by a <em>recursion</em> formula in this question:

f(n + 1) = f(n) + 3

Thus, the following term of the sequence is:

f(2) = f(1) + 3

f(2) = - 4 + 3

f(2) = - 1

The sequence whose <em>first</em> term is - 4 and defined recursively by the formula f(n + 1) = f(n) + 3 have the element - 1 as the <em>next</em> term. (Correct choice: B)

<h3>Remark</h3>

The statement is poorly formatted and reports typing mistakes. Correct statement is:

<em>A sequence is defined recursively by the formula f(n + 1) = f(n) + 3. The first term of the sequence is - 4. What is the next term in the sequence? </em><em>a)</em><em> - 7, </em><em>b)</em><em> - 1, </em><em>c)</em><em> 1, </em><em>d)</em><em> 7</em>

Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co-workers. Sam buys a case of water t
Brrunno [24]

It is given that Sylvia sells x number of bottles and Sam sells three times as many bottles as Sylvia sold to his co-workers.

So, number of bottles Sam sold is 3x.

It is also given that, number of remaining bottle Sylvia and Sam have same.

So,

24 - x = 36 - 3x

3x - x = 36 - 24

2x = 12

x = 6

Therefore, Sylvia sells 6 bottles.

Hence, this is the required solution.

Answer:

  $98.15

Step-by-step explanation:

2005 is 15 years after 1990. Using the formula we find ...

  c(15) = 63·1.03^15 ≈ 63·1.55797

  c(15) ≈ 98.152

An ounce of the chemical costs about $98.15 in 2005.
