Solve -2x-14=7X+6 for x. Round your answer to the nearest tenth.​

Answer:

4.78125

Step-by-step explanation:

Step 1

Find the mean

Mean = Sum of Terms/Number of Terms

Mean = 7+5+ 16+20+ 17+ 9+ 18+ 15/8

= 107/8

= 13.375

Step 2

Find the Mean Absolute Deviation

Mean Absolute Deviation formula = |x - Mean|/n

Mean Absolute Deviation =[ |7 - 13.375| +| 5 -13.375|+ |16 - 13.375| + |20 - 13.375| +| 17 - 13.375| + |9 - 13.375 | +| 18 -13.375|+|15 - 13.375|] /8

Mean Absolute Deviation = 4.78125

Therefore, the Mean Absolute Deviation (M.A.D.) for these students = 4.78125

Answer:

[tex]y = \frac{1}{5}x[/tex]

Step-by-step explanation:

Given

Yearly Cost for members; [tex]y = \frac{1}{10}x + 6[/tex]

Required

Determine the yearly cost for non members

From the question, we understand that:

A non member pays $0.20 for each game;

Yearly cost is then calculated as thus;

y = Amount * Number of Games

Where:

Amount = $0.2 and Number of Games = x

[tex]y = 0.20 * x[/tex]

Convert 0.2 to fraction

[tex]y = \frac{2}{10} * x[/tex]

Divide the numerator and the denominator by 2

[tex]y = \frac{1}{5} * x[/tex]

[tex]y = \frac{1}{5}x[/tex]

Hence, the yearly cost for non members is

[tex]y = \frac{1}{5}x[/tex]

Answer:

y = y equals 1 Over 5 x. x

Best regards!

The mixed number  [tex]2\frac{7}{12}[/tex]  as a decimal is approximately 2.58333 as per th rule of simplification.

To simplify [tex]2\frac{7}{12}[/tex] as a decimal form, we need to convert the mixed number to an improper fraction and then perform the division.

First, multiply the whole number (2) by the denominator of the fraction (12), and add the numerator (7). This gives us 2 x 12 + 7 = 24 + 7 = 31.

Now, the numerator of the improper fraction is 31, and the denominator remains the same (12). Therefore, the improper fraction is 31/12.

To convert this improper fraction to decimal form, divide the numerator (31) by the denominator (12):

31 ÷ 12 = 2.58333 (rounded to five decimal places)

Hence,  [tex]2\frac{7}{12}[/tex]  as a decimal is approximately 2.58333.

It's important to note that the decimal form is an approximation because fractions can have repeating decimal representations. In this case,  [tex]2\frac{7}{12}[/tex]  can be expressed exactly as a fraction but has a repeating decimal approximation when converted to decimal form.

The complete question:

Simplify 2 7/12 as a decimal form.

Answer:

14 years

Step-by-step explanation:

To find the answer, you have to use the formula to calculate the time period:

t=(1/r)*(A/P-1), where:

t= time period

r= rate of interest=5%

A= accrued amount=$8,500

P= principal amount=$5,000

Now, you can replace the values in the formula:

t=(1/0.05)*(8,500/5,000-1)

t=20*0.7

t=14

According to this, the answer is that the money has been 14 years in the account.

Answer:

Step-by-step explanation:

Let the amount of correct answer gotten be x and that of wrong answer be y. The sum of Jay score = 5x+ (-2)y [since(+5)marks are give for every correct answer and (-2)marks for every incorrect answer]

If Jay answered all questions and scored (-12)m, then 5x - 2y = -12

If Jay got four answers correctly, the number of correct answers x = 4

Substituting x = 4 into the equation 5x - 2y = -12 to get the value of y, we will have;

5(4) - 2y = -12

20 - 2y = -12

-2y = -12-20

-2y = -32

y = 16

This means that Jay attempted 16 incorrect answers.

[tex]\Large \boxed{\mathrm{E}}[/tex]

Step-by-step explanation:

The x-intercept is when y = 0.

[tex]y = 3x + 1[/tex]

Let y = 0.

[tex]0=3x+1[/tex]

Subtracting 1 from both sides.

[tex]-1=3x[/tex]

Dividing both sides by 3.

[tex]\frac{-1}{3} =x[/tex]

The x-intercept is negative.

First, find the cost of how much fence Mary needs per side.

10 * 5 = 50

10 * 5 = 50

6 * 5 = 30

6 * 5 = 30

Second, add all together.

50 + 50 + 30 + 30 = 160

Therefore, the total cost of the fence will be $160.

When a fraction equals zero

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 y-18x-12

 ———————— • 6 = 0 • 6

    6    

Now, on the left hand side, the  6  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  y-18x-12  = 0

Equation of a Straight Line

4.2     Solve   y-18x-12  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-18x-12  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 12/1 so this line "cuts" the y axis at y=12.00000

 y-intercept = 12/1  = 12.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 2/-3 Our line therefore "cuts" the x axis at x=-0.66667

 x-intercept = 12/-18 = 2/-3  = -0.66667  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 12.000 and for x=2.000, the value of y is 48.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 48.000 - 12.000 = 36.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = 36.000/2.000 = 18.000  

Geometric figure: Straight Line

 Slope = 36.000/2.000 = 18.000

 x-intercept = 12/-18 = 2/-3 = -0.66667

 y-intercept = 12/1 = 12.00000
