Six less than the product of 5 and a number is equal to 2.

Answers

5x-6=2
That is the formula

Six less than the product of 5 and a number is equal to 2 is represented as 5x - 6 = 2 and x becomes 1.6

Let's break down the statement and solve the equation step by step.

The statement is: "Six less than the product of 5 and a number is equal to 2."

Let's translate this into an equation.

Let "x" be the number we want to find.

The product of 5 and the number "x" is 5x.

"Six less than the product of 5 and a number" is 5x - 6.

Now, we have the equation: 5x - 6 = 2.

To solve for "x," follow these steps:

Step 1: Add 6 to both sides of the equation to isolate the term with "5x."

5x - 6 + 6 = 2 + 6

This simplifies to: 5x = 8.

Step 2: Now, to find the value of "x," divide both sides of the equation by 5.

(5x) / 5 = 8 / 5

This simplifies to: x = 8/5.

So, the value of the number "x" is 8/5, which is equivalent to 1.6.

Therefore, the number is 1.6.

Answers

Answer:

2km/hr

Step-by-step explanation:

The formula for calculating speed is expressed as;

Distance = 6km

Time = 3hours

Speed = 6km/3hr

Speed = 2km/hr

Hence the speed travelled is 2km/hr

Suppose the postal service charges $10.30 per pound on the package shipped to England what is this rate in dollars per ounce

Answers

Given:

The postal service charges $10.30 per pound on the package shipped to England.

To find:

The rate in dollars per ounce.

Solution:

We know that,

1 pound = 16 ounce

1 Dollar per pound = [tex]\dfrac{1}{16}[/tex] dollar per ounce.

1 Dollar per pound = 0.0625  dollar per ounce.

We have, the postal service charges $10.30 per pound on the package shipped to England.

Using the above conversion, we get

$10.30 Dollar per pound = [tex]10.30\times 0.0625 [/tex] dollar per ounce

$10.30 Dollar per pound = [tex]0.64375 [/tex] dollar per ounce

Therefore, the required rate is $0.64375  per ounce.

How many vehicles does the salesperson need to sell in a month to earn at least $6000? Explain how you found your answer.

Answers

Answer: 15 vehicles

Step-by-step explanation:

The first part of the question reads:

A salesperson at a car dealership earns a monthly salary of $2,400 and $250 for each vehicle sold.

The Sales person wants to get to $6,000 for the month.

Their salary already gives them $2,400 so the amount they have to make in commission is:

= 6,000 - 2,400

= $3,600

They earn $250 per car sold so the number of cars they need to sell is:

= 3,600 / 250

= 14.4

Round this up to 15 cars because rounding down to 14 would not be enough to reach the total of $6,000.

15 cars * $250 commission = $3,750 which is more than the $3,600 required so the condition has been satisfied.

To earn at least $6,000, they will have to sell 15 cars.

Write the following Arithmetic Sequence using a Recursive Formula: an = -7 + 3(n – 1)
a1 = 3, an = an-1 – 7
a1 = -7, an = an-1 + 3
a1 = -7, an = an+1 + 3
a1 = 3, an = an+1 – 7

Answer:

  (b)  a[1] = -7, a[n] = a[n-1] + 3

Step-by-step explanation:

Comparing the given formula to the general form for the n-th term of an arithmetic sequence ...

  an = a1 +d(n -1)

we see that the first term (a1) is -7, and the common difference (d) is +3.

The recursive version of the sequence definition is ...

  a[1] = a1

  a[n] = a[n-1] +d

So, the appropriate choice is ...

  a[1] = -7, a[n] = a[n-1] +3

Answers

Answer:

answer is id.k

Step-by-step explanation:

The correct equation to represent the condition is,

⇒ 2 + 3 1/4x = 1/2 + 5 1/2x

And, The volume of the paint is, 2/3 quartz.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Liam and Evan are mixing paint. Liam uses 2 quarts of yellow paint and adds 3 1/4 jars of blue paint.

And, Evan uses 1/2 quart of yellow paint and adds 5 1/2 jars of red paint. They end up with the same volume of paint.

Let the volume of the paint is, x

Hence, We can formulate;

The correct equation to represent the condition is,

⇒ 2 + 3 1/4x = 1/2 + 5 1/2x

And, Solve for x as;

⇒ 2 + 13/4x = 1/2 + 11/2x

⇒ 2 - 1/2 = 11/2x - 13/4x

⇒ 3/2 = (44 - 26)x / 8

⇒ 12 = 18x

⇒ x = 12/18

⇒ x = 2/3

Hence, The volume of the paint is, 2/3 quartz.

What is a polygon?

In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:

Triangle Quadrilateral        Pentagon Hexagon Heptagon Octagon Nonagon

When a trapezoid is translated 8 units down, all of its points will move down 8 units, which means the y-coordinates of each point will decrease by 8.

Therefore, the y-coordinates of the new trapezoid will be different from the y-coordinates of the original trapezoid.

However, A, B, and C are all true statements.

The new trapezoid will have the same orientation (the same angles between its sides), the same shape (the same ratio of the lengths of its sides), and the same size (the same area).

The only difference is that the new trapezoid will be shifted down by 8 units.

The correct factorization of 12x'2 - 157x - 40: A) (3x -8)(4x - 5) B) (3x - 40)(4x + 1) C) (12x - 1)(x + 40) D) (12x - 5)(x-8)​

Answers

Answer:

B

Step-by-step explanation:

12x² - 157x - 40

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 12 × - 40 = - 480 and sum = - 157

The factors are + 3 and - 160

Use these factors to split the x- term

12x² + 3x - 160x - 40 ( factor the first/second and third/fourth terms

= 3x(4x + 1) - 40(4x + 1) ← factor out (4x + 1) from each term

= (4x + 1)(3x - 40) ← in factored form → B
