The difference between three times a number and five more than two times the number

Answer:

Rational: 0.51 and 0.52

Irrational: sqrt(.26) and sqrt(.27)

Answer:

Mean: 6

Median: 4.5

Mode: 4

Range: 13

Step-by-step explanation:

Answer:

mean = 6

median = 4.5

mode = 4

range = 13

Step-by-step explanation:

To find the mean, median, mode and range firstly place the numbers in ascending order.

2, 4, 7, 15, 7, 4, 5, 4

= 2, 4, 4, 4, 5, 7, 7, 15

(Mean is the average of all the data in a set.)

[tex] \\ \tt2, 4, 4, 4, 5, 7, 7, 15[/tex]

[tex] \\ \tt = \frac{2 + 4 + 4 + 4 + 5 + 7 + 7 + 15}{8} [/tex]

[tex] \\ \tt = \frac{48}{8} [/tex]

(Median is the middle number of the set.)

2, 4, 4, 4, 5, 7, 7, 15

median

= 4+5/2

= 9/2

= 4.5

(Mode is the number which appears multiple times.)

2, 4, 4, 4, 5, 7, 7, 15

mode = 4

(Range is the number which comes by subtracting the smallest number to the largest number.)

2, 4, 4, 4, 5, 7, 7, 15

Largest number = 15

Smallest number= 2

range

= 15-2

= 13

Step-by-step explanation:

2x + 3 = 6

The best next step would be to subtract 3 from both sides of the equation.

2x + 3 - 3 = 6 - 3

⇒ 2x = 3

Answer:

2y°+y+10°+50°=180°[by sum of angles of triangle is 180°]

3y + 60°=180°

3y=120°

y=120/3

y=40

option a.

Step-by-step explanation:

[tex] \frac{17}{6} = \frac{12 + 5}{6} = \frac{12}{6} + \frac{5}{6} = 2 + \frac{5}{6} = 2 \frac{5}{6} [/tex]

PRELIMINARY

Fractions are part of a whole. For example, if an object is divided into two equal parts, the value of each part is half or one-half of the total number of objects. Fractions can be expressed in the form: a/b

DISCUSSION

Fractions also have fractions in different forms but have the same value which are called equivalent fractions. Fractions can also be simplified. To find a fraction equal to a fraction, we can multiply (×) or divide (÷) the numerator and denominator of the fraction by the same number. And to simplify fractions, we can divide (÷) the numerator and denominator of the fraction with the same number.

**

There are various forms of fractions, including:

**

Now from the discussion above, it turns out that ordinary fractions still have two more types, namely =

➳ A pure fraction is a fraction whose numerator is smaller than the denominator.

➳ An impure fraction is a fraction whose numerator is greater than its denominator.

**

The arithmetic operations also apply to fractions, including:

Given that x° and 2x° are same-side interior angles, the value of x is: 60.

Recall:

x° and 2x° are same-side interior angles.

Therefore:

x° + 2x° = 180°

3x° = 180°

x = 180/3

x = 60

In summary, given that x° and 2x° are same-side interior angles, the value of x is: 60.

Answer:

First car consumed 25 gallons

Second car consumed 30 gallons

Step-by-step explanation:

Let x = first car gallons

     y = second car gallons

15x + 25y = 1125

x + y = 55

Let's use substitution method

Subtract both sides of the bottom equation by y

x + y = 55

  - y     - y

x = 55 - y

Plug in the new x into the top equation

15(55 - y) + 25y = 1125

825 - 15y + 25y = 1125

10y + 825 = 1125

Subtract 825 from both sides

10y + 825 = 1125

      - 825    - 825

10y = 300

Divide by sides by 10

10y/10 = 300/10

y = 30

The second car consumed 30 gallons

Plug in the new y into one of the original equations; let's use the bottom one

x + 30 = 55

  - 30   - 30

x = 25

The first car consumed 25 gallons

Answer:

Monday = 1,700

Tuesday = 1,900

Wednesday = 2,100

Step-by-step explanation:

i started by dividing the total (5700) by 3 (because there were 3 days)

5700 ÷ 3 = 1900

that gives us our middle number. from there, you subtract 200 to get the first day's number and add 200 to get the third day's number

1900 - 200 = 1700

1900 + 200 = 2100

Answer:

To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

Step-by-step explanation:

The approximate length of one side of the piece of cheese is 3.16 inches so option (C) will be correct.

A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.

Area of square = Side²

The perimeter of the square = 4× side

Length of diagonal of square = √(2) × side

Let's say the length of the side of the piece is x

Then,

Area = x²

Since it covers 10 inches² so it means it has an area of  10 inches²

So,

x² = 10 ⇒ x = 3.16 inches.

Hence "The approximate length of one side of the piece of cheese is 3.16 inches".

Hope this helps you. I apologize if it’s incorrect.  

The answer is (x+4)² + y² = 16

x² + y² - 8x = 0

[reorder the terms]

x² - 8x + y² = 0

[to complete the square, add 16 to both sides]

x² - 8x + 16 + y² = 16

[write the expression as a product and 16 as an exponent]

x² - 2 × x × 4 + 4² + y² = 16

[using a² + 2ab + b² = (a + b)², factor the expression]

(x + 4)² + y² = 16

Since this equation can be written as

(x + p)² + (y - q)² = r², it represents a circle.
