A number plus one is greater than negative five and less than three.

Answer:

The mean age of the frequency distribution for the ages of the residents of a town is 43 years.

Step-by-step explanation:

We are given with the following frequency distribution below;

    Age                      Frequency (f)               X                    

    0 - 9                            30                         4.5                   135

   10 - 19                           32                        14.5                  464

   20 - 29                         12                         24.5                 294

   30 - 39                         20                        34.5                 690

   40 - 49                         25                        44.5                1112.5

   50 - 59                         53                        54.5                2888.5

   60 - 69                         49                        64.5                3160.5

   70 - 79                          13                         74.5                968.5

   80 - 89                          8                          84.5                676        

   Total                            242                                              10389      

Now, the mean of the frequency distribution is given by the following formula;

                         Mean =  

                                    =    = 42.9 ≈ 43 approx.

Hence, the mean age of the frequency distribution for the ages of the residents of a town is 43 years

Hope this helps

plz mark brainliest

The midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).

A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.

The midpoint is calculated by using the formula:- ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2.

Given points are R(-3,3) and S(1,6). The midpoint of the given points are calculated as below:-

M = (-3+1 ) / 2 , ( 3 + 9 ) / 2

M = ( -1,4.5)

Therefore, the midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).

x=-1

x is equal to -1

Answer:

-3x = x + 4

umm yea! this is correct i checked it!

Answer:

x = 3

z = (-21)/2

x = 9

x = 1/7

Step-by-step explanation:

Solve for x:

6 x - 5 = 2 x + 7

Subtract 2 x from both sides:

(6 x - 2 x) - 5 = (2 x - 2 x) + 7

6 x - 2 x = 4 x:

4 x - 5 = (2 x - 2 x) + 7

2 x - 2 x = 0:

4 x - 5 = 7

Add 5 to both sides:

4 x + (5 - 5) = 5 + 7

5 - 5 = 0:

4 x = 7 + 5

7 + 5 = 12:

4 x = 12

Divide both sides of 4 x = 12 by 4:

(4 x)/4 = 12/4

4/4 = 1:

x = 12/4

The gcd of 12 and 4 is 4, so 12/4 = (4×3)/(4×1) = 4/4×3 = 3:

Answer: x = 3

____________________________________

Solve for z:

3 z - 2 = 5 z + 19

Subtract 5 z from both sides:

(3 z - 5 z) - 2 = (5 z - 5 z) + 19

3 z - 5 z = -2 z:

-2 z - 2 = (5 z - 5 z) + 19

5 z - 5 z = 0:

-2 z - 2 = 19

Add 2 to both sides:

(2 - 2) - 2 z = 2 + 19

2 - 2 = 0:

-2 z = 19 + 2

19 + 2 = 21:

-2 z = 21

Divide both sides of -2 z = 21 by -2:

(-2 z)/(-2) = 21/(-2)

(-2)/(-2) = 1:

z = 21/(-2)

Multiply numerator and denominator of 21/(-2) by -1:

Answer: z = (-21)/2

________________________________________

Solve for x:

5 x + 2 x - 15 = 4 x + 12

Grouping like terms, 5 x + 2 x - 15 = (5 x + 2 x) - 15:

(5 x + 2 x) - 15 = 4 x + 12

5 x + 2 x = 7 x:

7 x - 15 = 4 x + 12

Subtract 4 x from both sides:

(7 x - 4 x) - 15 = (4 x - 4 x) + 12

7 x - 4 x = 3 x:

3 x - 15 = (4 x - 4 x) + 12

4 x - 4 x = 0:

3 x - 15 = 12

Add 15 to both sides:

3 x + (15 - 15) = 15 + 12

15 - 15 = 0:

3 x = 12 + 15

12 + 15 = 27:

3 x = 27

Divide both sides of 3 x = 27 by 3:

(3 x)/3 = 27/3

3/3 = 1:

x = 27/3

The gcd of 27 and 3 is 3, so 27/3 = (3×9)/(3×1) = 3/3×9 = 9:

Answer: x = 9

__________________________________________

Solve for x:

35 x + 2 = 7

Subtract 2 from both sides:

35 x + (2 - 2) = 7 - 2

2 - 2 = 0:

35 x = 7 - 2

7 - 2 = 5:

35 x = 5

Divide both sides of 35 x = 5 by 35:

(35 x)/35 = 5/35

35/35 = 1:

x = 5/35

The gcd of 5 and 35 is 5, so 5/35 = (5×1)/(5×7) = 5/5×1/7 = 1/7:

Answer: x = 1/7

Answer:

x = -18

Step-by-step explanation:

Step 1: Define

w(x) = 5/6x - 3

w(x) = -18

Step 2: Substitute and Evaluate

-18 = 5/6x - 3

-15 = 5/6x

x = -18

Answer:

x = 31

Step-by-step explanation:

I will make the explanation easy for you to understand.

Step 1: Subtract 12x from both sides.

13x − 15 − 12x = 12x + 16 − 12x

x − 15 = 16

Step 2: Add 15 to both sides.

x − 15 + 15 = 16 + 15

x = 31

Answer:

156 miles

Step-by-step explanation:

155.79-16.95=138.84

138.84/0.89=156

We can tell that the whole L shaped angle is 90 degrees because it has the little box in the corner. Now, the 90 degree angle is split into two parts with that line coming from the box. Those two parts of the whole 90 degree angle add up to 90 degrees.

90 = 4v + 2 + 9v - 3

Now, let's solve for v. Combine like terms.

90 = 13v - 1

Add 1 to both sides.

91 = 13v

Divide both sides by 13

7 = v

Answer:

number is 5

Step-by-step explanation:

The reciprocal of a number n is [tex]\frac{1}{n}[/tex] , thus

n - [tex]\frac{1}{n}[/tex] = [tex]\frac{24}{5}[/tex]

Multiply through by 5n to clear the fractions

5n² - 5 = 24n ( subtract 24n from both sides )

5n² - 24n - 5 = 0 ← in standard form

(n - 5)(5n + 1) = 0 ← in factored form

Equate each factor to zero and solve for n

n - 5 = 0 ⇒ n = 5

5n + 1 = 0 ⇒ 5n = - 1 ⇒ n = - [tex]\frac{1}{5}[/tex]

However, n > 1 , thus n = 5

That is the number is 5

We can verify this value is true by substituting it back into the equations and as a result also solving for the working y value.

x = 2 -> y = 2(x) - 3

2(2) - 3 = 4 - 3 = 1

y = 1

x = 2 -> y = -(x) + 3

-(2) + 3 = -2 + 3 = 1

y = 1

What are sides of a pentagon with different sides ?

If the sides of a pentagon are not equal in measure, it is termed as an irregular pentagon. In this case, the perimeter of the pentagon can be calculated by using the basic formula, Perimeter = sum of its sides.

Given,

side 1 = 2x

side 2 = 10

side 3 = x+2

side 4 = 11

side 5 = 3x-2

Sum of all the sides of the pentagon,

2x+10+(x+2)+11+(3x-2)=63

2x+10+x+2+11+3x-2=63

6x+21=63

6x=63-21

6x=42

x=42/6

x=7
