Answer:

x=−20

Step-by-step explanation:

Step by Step Solution:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

         -4     -4 • 5

   -4 =  ——  =  ——————

         1        5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (-4 • 5)     x + 20

————————————  =  ——————

     5             5  

Equation at the end of step

:

 x + 20

When a fraction equals zero

3.1    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:

 x+20

 ———— • 5 = 0 • 5

  5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x+20  = 0

Solving a Single Variable Equation:

3.2      Solve  :    x+20 = 0

Subtract  20  from both sides of the equation :

                     x = -20

One solution was found :

x = -20

Answer:

x=-4.5 or -9/2

Step-by-step explanation:

The first step is to isolate x to do this you add 5 to both sides which then gives you -2x=9 the next step is to divide by negative 2 which would give you -9/2 which simplifies to -4.5.

Step-by-step explanation:

the question should be : "which describes a POSSIBLE domain and range definition of the function and is inverse ?"

because this is just a matter of definition. the function itself would not suggest any limits.

and in that regard the function definition is basically irrelevant.

the domain of any basic function is the range of the inverse, and the range of the basic function is the domain of the inverse.

so, the second set of definitions is not possible, if we are really trying to define the inverse function.

Answer:

$883.26

Step-by-step explanation:

Multiply the regular price ($1,049) by the Percent Discount (20%). To do this, multiply 1,049 by 0.2 :

1,049(0.2)=$209.8

After multiplying, you get the amount taken off by the discount. So you subtract the amount you got ($209.8) from the original amount ($1049) :

$1049-$209.8=$839.2

Now that you've calculated the discount price, you can calculate the sales tax. Make sure you do this part second, because it says to do so in the problem.

To calculate the sales tax, you do the same as above. Multiply your NEW cost ($839.2) by the sales tax (5.25%). The equation is:

$839.2(5.25%)=$44.058

Round $44.058 to $44.06. Since this is a Sales Tax, you add this on to your previous amount of $839.2

$839.2+$44.06=$883.26

The final cost of the computer is $883.26

3y= -6

isolate y by dividing by 3 to each side and get

y=-2

If they were positive it would be square root of 50 but its a larger negative njmber

So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.

Hope it helped :)

The original price was $15.00

The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:

18 = x × (1 + 20%)

18 = x × 1.20

18 = 1.20x

x = 18 / 1.20

x = $15.00

In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.

Step-by-step explanation:

If the angle measures x, then the supplement measures 180-x.

This means x-132.6=180-x, and thus x=156.3

This means the angles measure 156.3 and 23.7 degrees.

Answer:

r = 1.7389 in

Step-by-step explanation:

(A) Volume of hollow block = 540 in^3

(B) volume of block without Hollows = b×d×h

= 6 ×16 ×8

= 768 in^3

(C) volume of 3 hollows = 3 ×( pi ×r^2 h)

= 3 ×( pi ×r^2 ×8)

= 24 ×pi ×r^2

solve,

A = B - C

540 = 768- (24 ×pi ×r^2)

r^2 = (768- 540) / 24 pi

r = root(3.023943919)

r = 1.7389 in

Answer:

(-3, -6)

Step-by-step explanation:

The coordinate of point P is, (- 3, - 6)

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

We have to given that;

Point P partitions directed line segment AB in the ratio of 3 to 4.

And, A (-9, -9) and B (5,-2).

Now, The coordinate of Point P is find as;

⇒ P (x, y) = (3×5 + 4×- 9/ (3+ 4) , 3×-2 + 4×- 9 / (3 + 4) )

               = (15 - 36/7 , - 6 - 36/7)

I just did it and I got it right.

The probability of selecting a class that runs between 51.0 and 52.5 minutes is 0.3 or 30%.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

Since the lengths of the classes are uniformly distributed between 49.0 and 54.0 minutes, the probability of a class running between any two values within this range is proportional to the length of the interval between these two values.

The total length of the possible class periods is:

54.0 minutes - 49.0 minutes

= 5.0 minutes

So, the probability of a randomly selected class running between 50.75 and 51.75 minutes can be calculated as follows:

Length of the interval

= 51.75 minutes - 50.75 minutes

= 1.0 minute

Probability = (Length of the interval) / (Total length of possible class periods)

Probability = 1.0 minute / 5.0 minutes

Probability = 0.2

Therefore, the probability of a given class period running between 50.75 and 51.75 minutes is 0.2 or 20%.

Similarly, the probability of selecting a class that runs between a and b minutes, where a and b are between 49.0 and 54.0 minutes and a < b, is given by:

Probability = (Length of the interval between a and b) / (Total length of possible class periods)

Probability = (b - a) / 5.0

For example, if we want to the probability of selecting a class that runs between 51.0 and 52.5 minutes, we would have:

Probability = (52.5 - 51.0) / 5.0

Probability = 0.3 or 30%

Thus,

The probability of selecting a class that runs between 51.0 and 52.5 minutes is 0.3 or 30%.
