Algebraic expression for each statement in terms of w would be:

Each pencil will cost: w/5.

A pen will cost: w/5 + 0.35

Number of pencils 20 dollars will buy = w/5 = 20/5 =4 pencils.

<h3>What is an Algebraic Expression?</h3>

Algebraic expression in mathematics is an expression that is made up of variables, constant, and mathematical symbols, which can be used to represent a statement.

Thus:

Let w represents the price for 5 pencils.

Each pencil will cost: w/5.

A pen will cost: w/5 + 0.35

a. cost in dollars for a pen = w/5 + 0.35

b. Number of pencils 20 dollars will buy = w/5 = 20/5 =4 pencils.

Xelga [282]

Answer:

option 2

Step-by-step explanation:

Substitute x = - 5 into f(x) , that is

f(- 5) = 4(- 5) - 7 = - 20 - 7 = - 27

Write a rule for the nth term of the arithmetic sequence:<br><br> a11= 50, d = 7
ivolga24 [154]

Answer:

Required rule for n^{th} is a_{n}=7n-27.

Step-by-step explanation:

Given that,

a_{11} = 50,\  \  d=7

From the question: we have to write the n^{th} term of Arithmetic sequence.

Arithmetic Sequence or Arithmetic progression (A.P) : It is a sequence which possess that difference between of two successive sequence is always constant.

                a_{1} ,a_{2},a_{3},a_{4}.....................a_{n-1},a_{n}

                                        where, a_{1} is the first term of A.P

                                                     d is the common difference.

                                                     a_{n} is the last term or general term.

The above sequence to be in A.P then their common difference should be equal.

          d=a_{2}-a_{1} =a_{3}-a_{2}=a_{4} -a_{3} ..........................a_{n}-a_{n-1}

Now, Formula of General Term is a_{n}=a+(n-1)d

So,                                                    a_{11}= a+(11-1)d\\        a_{11} = a+10d

 Substituting the value of   a_{11} = 50,\  \  d=7 we get,

                                                         50=a+10\times7\\50=a+70\\a=-20

Then General term (a_{n}) of given data is

                                                         a_{n}=-20+(n-1)7\\a_{n}=-20+7n-7\\a_{n}=7n-27

Therefore, Required rule for n^{th} is a_{n}=7n-27.

Write an expression to represent: "the difference of 8 squared and a number"
Gnom [1K]

Answer:

The expression is (64 - x).

Step-by-step explanation:

The statement is:

"the difference of 8 squared and a number"

Let the number be denoted by <em>x</em>.

The value of 8 squared is:

8^{2}=8\times 8\\

   =64

Then the expression for the provided statement is:

(64 - x)

Thus, the expression is (64 - x).
