eight times the reciprocal of a number equals 4 times the reciprocal of 2. find the number

Answers

Answer:

The number is 4

Step-by-step explanation:

Let the number  = 'x'

Reciprocal of 'x' = 1/x

Reciprocal of 2 = 1/2

8 times the reciprocal of 'x' = [tex]8*\frac{1}{x}\\[/tex]

[tex]8*\frac{1}{x}= 4* \frac{1}{2}\\\\8*\frac{1}{x}= 2\\[/tex]

Now multiply both sides by x

[tex]8*\frac{1}{x}*x = 2*x\\\\8 = 2x[/tex]

Now divide both sides by 2

[tex]\frac{8}{2}=\frac{2x}{2}\\\\4 = x[/tex]

x = 4

  5/2 = 2.5

Step-by-step explanation:

The slope is given by ...

  m = (y2 -y1)/(x2 -x1)

Using the first two lines in the table, this is ...

  m = (10 -5)/(2 -0) = 5/2

The slope of the line is 5/2.

Answer:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Step-by-step explanation:

-29= x + 8
what is x

Answers

Answer:

x=-37 (the answer should have a negative sign.)

Step-by-step explanation:

To solve this problem, isolate the value of x from one side of the equation.

First, switch sides.

-29=x+8

x+8=-29

Then, subtract by 8 from both sides.

x+8-8=-29-8

Solve.

-29-8=-37

x=-37

Therefore, the final answer is x=-37.

Answers

Answer:

H0 : σ² = 10

H1 : σ² ≠ 10

X² = 20.124

Pvalue = 0.064776

there is significant evidence to conclude that the rebound lengtb of rockfall down a slope is not 10m²

Step-by-step explanation:

Given the data:

10.94 13.71 11.38 7.26 17.83 11.92 11.87 5.44 13.35 4.90 5.85 5.10 6.77

Using a calculator ;

The sample variance, s² = 16.77

α = 0.10

The null and alternative hypothesis :

H0 : σ² = 10

H1 : σ² ≠ 10

The test statistic :

X² = [(n - 1)*s² ÷ σ²]

s² = 16.77

n = sample size = 13 ; s²

X² = [(13 -1)*16.77 ÷ 10

X² = (12 * 16.77) / 10

X² = 201.24 / 10

X² = 20.124

The Pvalue using a Pvalue calculator ; degree of freedom (df) = 13 - 1 = 12

Pvalue = 0.064776

Pvalue < α ; Hence we reject the null

Hence, there is significant evidence to conclude that the rebound lengtb of rockfall down a slope is not 10m²

If you can buy 48 plaintains for $24 then how many can you buy with $4 ?

Answers

Answer:

8 plantains

Step-by-step explanation:

48=$24

x=. $4

192=24x , x= 192÷24= 8

Answer:

8 plantains

Step-by-step explanation:

Cost and number of plantains are in proportion

Number of plantains that can be bought for $ 4 be 'x'

48 : 24 :: x : 4

Product of means = product of extremes

24 * x = 48*4

       [tex]x = \frac{48*4}{24}[/tex]

      x = 2 * 4

      x = 8

Answers

the answer is (-8) because x=4, y=-6, z=11

These consists of more than 1 equation with unknown variables. The value that is not a solution in (x,y, z)is -8

System of equations

These consists of more than 1 equation with unknown variables. Given the set of equations

x+y+z=9

x-y-z=-1

x-y+z= 21

Add 1 and 2

2x = 9 - 1

2x = 8

x = 4

Subtract 2 and 3

-2z = -22

z = 11

Determine the value of y

x +y + x = 9

4 + y + 11 = 9

y = 9 - 15

y = -6

Hence the value that is not a solution in (x,y, z)is -8

Answers

Answer:

x = 0 , 5

Step-by-step explanation:

[tex]\frac{2x}{x-3}=\frac{3x}{x-2}[/tex]

Cross multiply,

2x* ( x - 2) = 3x *(x - 3)

2x*x - 2*2x  = x*3x - 3*3x

2x² - 4x   = 3x² - 9x

subtract 2x² from both sides

-4x = 3x² - 2x² - 9x           {Combine like terms}

-4x = x² - 9x

Add 9x to both sides

-4x+ 9x = x²

x² = 5x

x² - 5x = 0
