Answers

Answer 1

Answer:

length is 17 in, width is 20

Step-by-step explanation:

let's shape this as an algebraic equation, where x= the length of one side.

since the width is 3 inches longer than the length, x will be the length and x+3 will be the width.

the perimeter is 74 in, and the perimeter is the added length of all sides. in a rectangle, 2 sides are the length and 2 sides are the width, so:

74 = 2x + 2(x + 3)

let's distribute the 2.

74 = 2x + 2x + 6

now, we combine the x's.

74 = 4x + 6

after this step, subtract 6 from the right to add it to the left side.

68 = 4x

finally, divide both sides by 4.

17 = x

perfect! now that we know the length, we just have to add 3 to find the width.

17 + 3 = 20

Milan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $48 and costs an additional $0.20 per mile driven. The
second plan has an initial fee of $57 and costs an additional $0.15 per mile driven.
For what amount of driving do the two plans cost the same?
What is the cost when the two plans cost the same?
If you do not have both of the answers do not bother to reply.

Answers

Answer:

For 180 miles of driving the two plans will cost the same, at a price of $84.

Step-by-step explanation:

1 - Set up the system of equations

Let x represent the miles driven

Let y represent the cost

First Plan:

y = $48 + $0.20x

Second plan:

y = $57 + $0.15x

Note that both are set equal to y, that means we can substitute y in one equation with the other equation because y = y

2 - Substitute

$57 + $0.15x = y = $48 + $0.20x

$57 + $0.15x = $48 + $0.20x

3 - Get the variables on one side and the constants on the other and then get x alone

 $57 + $0.15x = $48 + $0.20x

- $48                 - $48

   $9 + $0.15x = $0.20x

         - $0.15x  - $0.15x

                  $9 =  $0.05x

           $9/0.05 = $0.05x/0.05

                    x = 180 Miles

"For what amount of driving do the two plans cost the same?

For 180 miles of driving the two plans will cost the same.

4 - Plug 180 in for x in either equation and solve to find the cost at which they equal

y = $48 + $0.20x

y = $48 + $0.20(180)

y = $48 + $36

y = $84

"What is the cost when the two plans cost the same?"

$84 is the cost when the two plans cost the same

Step-by-step explanation:

The commutativity property is used to get

-12×13×1/3 = -12×1/3×13

What is Commutative property?

According to mathematics, an arithmetic operation is commutative if switching the operands' positions has no effect on the computation's outcome.

When two numbers A and B are provided, the commutative property of the numbers formula is as follows:

A+B=B+A

A×B=B×A

A-B≠B-A

A÷B≠B÷A

According to the commutative property formula, the outcome is unaffected by the sequence in which two integers are added or multiplied. However, the order of the integers matters for subtracting and dividing any two real numbers, thus it cannot be altered.

How to solve?

The commutativity property is used to get

-12×13×1/3 = -12×1/3×13

such that the evaluation becomes easier, which is to get 12×1/3=4.

The commutativity property is used as follows:

-12×(13×1/3)=-12×(1/3×13)

If the marginal revenue (in dollars per unit) for a month is given by MR = −0.5x + 400, what is the total revenue from the production and sale of 30 units?

Answers

Given:

Marginal revenue (in dollars per unit) for a month is

[tex]MR=-0.5x+400[/tex]

To find:

The total revenue from the production and sale of 30 units.

Solution:

We know that, total revenue is integration of marginal revenue with respect to quantity.

[tex]TR=\int MR dx[/tex]

[tex]TR=\int (-0.5x+400) dx[/tex]

[tex]TR=-0.5\int x dx+400\int 1 dx[/tex]

[tex]TR=-0.5\times \dfrac{x^2}{2}+400x[/tex]

Now, substitute x=30 in the equation of Total Revenue (TR).

[tex]TR=-0.5\times \dfrac{30^2}{2}+400(30)[/tex]

[tex]TR=-0.5\times \dfrac{900}{2}+12000[/tex]

[tex]TR=-225+12000[/tex]

[tex]TR=11775[/tex]

Therefore, the total revenue from the production and sale of 30 units is $11,775.

2 x + 3 = x - 4

Answers

Answer:

-7

Step-by-step explanation:

2x + 3 = x - 4

so you first add four to both sides of the equal sign:

2x + 3 = x - 4

    + 4       + 4

making the equation:

2x + 7 = x

you now subtract 2x from both sides:

2x + 7 = x

-2x       - 2x

to get:

7 = -1x

you then divide both sides by -1:

7/-1 = -1x/-1

to get:

-7 equals x or x = -7
