Answer:

y= -2

Step-by-step explanation:

3y -15 =-21

add 15 to both sides

-15+ 15 =0 , -21+ 15 = -6

so we have

3y= -6

isolate y by dividing by 3 to each side and get

y=-2

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)

               = (- 21/7, - 42/7)

               = (- 3, - 6)

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

Answer:

75 miles/hour

Step-by-step explanation:

Cheetahs run 15 miles in 1/5 hours. To get it to be a full hour, you multiply 1/5 by 5. You will also have to multiply 15 by 5 to get the number of miles per hour, and you get 75. Cheetahs can run 75 miles in 1 hour.

Answer:

75 miles per hour

Step-by-step explanation:

ok wooo first question answered so don't trust me too much

so basically we need to find how many miles he runs in one hour and we have 1/5

so multiply 15 by 5

75

I don't know if your teacher wants you to do it in a different way so here's a little explanation on how teachers normally want you to do it

Solution:

The perimeter of the triangle is basically the sum of its sides.

[tex]\rightarrow P = (0.3x + 24) + (5x) + (0.2x - 15)[/tex]

Open the parenthesis:

[tex]\rightarrow P = 0.3x + 24 + 5x + 0.2x - 15[/tex]

Combine like terms:

[tex]\rightarrow P = x(0.3 + 0.2 + 5) + (24 - 15)[/tex]

Simplify the equation:

[tex]\rightarrow P = x(5.5) + (9)[/tex]

Further simplify:

[tex]\rightarrow P = 5.5x + 9[/tex]

Option D is correct.

Perimeter=Sum of three sides

Perimeter:-

Answer: 0.050

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%.

Step-by-step explanation:

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

————————————  =  ——————

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.
