Answer:

3, 4, 5

Step-by-step explanation:

so, we need to find all integers for which

23 <= 7x + 2 <= 37

=>

21 <= 7x <= 35

3 <= x <= 5

so, that is correct for x = 3, x = 4 and x = 5.

Riley and Francesca both commute to work. Riley's commute on the train takes 12 minutes more than one half as many minutes as Francesca's commute by car. It takes Riley 36 minutes to get to work. Write an equation to determine how many minutes it takes Francesca to get to work.

36 = one halfx − 12
36 = 2x − 12
36 = 2x + 12
36 = one halfx + 12

Answers

Answer:

36 = one half x + 12

Step-by-step explanation:

let : Francesca's times = x

according to the text, we can make the equation :

12 + (one half) x = 36

or 36 = one half x + 12

The equation for the given situation is 36=1/2 x+12. Therefore, option D is the correct answer.

Given that, Riley's commute on the train takes 12 minutes more than one-half as many minutes as Francesca's commute by car. It takes Riley 36 minutes to get to work.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the time taken by  Francesca's commute by car be x.

Now, 12 minutes more than one-half=1/2 x+12

According to the question, 36=1/2 x+12

The equation for the given situation is 36=1/2 x+12. Therefore, option D is the correct answer.

the sum of three numbers is 66.the second number is twice the first number and the third number is 3x the first number

what is the first and second number?​

Answers

Answer:

The first number: 11;

The second number: 22;

The third number: 33

Step-by-step explanation:

The first number: 11

The second number: 11 x 2 = 22

The third number: 11 x 3 = 33

11 + 22 + 33 = 66

Answer:

11 and 22

Step-by-step explanation:

let the first number ne x then second is 2x and third is 3x and sum is

x + 2x + 3x = 66 , that is

6x = 66 ( divide both sides by 6 )

x = 11

2x = 2 × 11 = 22

first number is 11 and second number is 22

A crew of highway workers paved 1/5 mile in 1/8 hour. If they work at the same rate, how much will they
pave in one hour?

A. 1 and 3/5 miles
B. 1 and 4/5 miles
C. 2 miles
D. 2 and 1/5 miles

Answers

Answer:

The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.

215 of a mile, in 20 minutes, how much in 60 minutes?#

They will pave 3 times more.

215×31=615 of a mile

615=25 of a mile

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.

Look at what happens:

215÷20×60

=215×120×603

=215×3 ← exactly the same maths.

=25

theta=45 degrees to write 2x^2+2xy+5y^2+6x-4y=40 in the x'y'-plane. Then identify the conic.

Answers

Answer:

Step-by-step explanation:

If the section is created by slicing the equation 2x² + 2xy + 5y² + 6x - 4y = 40 at 45°. Then the conic will be an ellipse.

What is a conic section?

A figure made up of a surface and a round cone intersecting. A conic section can be a circle, an ellipse, a parabola, or a hyperbola, based on the direction of the plane with regard to the cone.

The angle θ is 45° and the equation is 2x² + 2xy + 5y² + 6x - 4y = 40.

Then x will be

[tex]\rm x = x' \cos \theta - y' \sin \theta\\\\x = x' \cos 45- y' \sin 45\\\\x = \dfrac{x' - y'}{\sqrt2}[/tex]

Then y will be

[tex]\rm y = x' \sin \theta + y' \cos \theta\\\\y= x' \sin 45 + y' \cos 45\\\\y = \dfrac{x' + y'}{\sqrt2}[/tex]

Put these in the equation we have

[tex]\rm 2\left ( \dfrac{x' - y'}{\sqrt2} \right )^2 + 2\left ( \dfrac{x' - y'}{\sqrt2} \right )\left ( \dfrac{x' + y'}{\sqrt2} \right ) + 5 \left ( \dfrac{x' + y'}{\sqrt2} \right )^2+ 6\left ( \dfrac{x' - y'}{\sqrt2} \right ) - 4\left ( \dfrac{x' + y'}{\sqrt2} \right ) = 40[/tex]

On simplifying, we have

[tex]\rm 9x'^2 + 6x'y' + 5y'^2 + 10\sqrt2x' - 10 \sqrt2 y' - 80=0[/tex]

Then the value of a, b, and c will be

a = 2, b = 2, and c = 5

Then we have

[tex]\rm b^2 - 4ac = 2^2 - 4\times 2 \times 5 = 4 - 20 = -16[/tex]

Then b² - 4ac < 0, then the conic is ellipse.
