Simplify   1/k

2.1   Subtracting a whole from a fraction

     2     2 • k

  2 =  —  =  —————

       1       k  

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

1 - (2 • k)     1 - 2k

———————————  =  ——————

    k            k  

Simplify  2/k

3     2        (1-2k)

Simplify 3/k

 3     2        (1-2k)

(((—+2)-(—•k))-4)-——————  = 0

   k     k          k  

5.1   Adding a whole to a fraction

3                      (1 - 2k)

(((— +  2) -  2) -  4) -  ————————  = 0

   k                         k    

6.1   Subtracting a whole from a fraction

       2     2 • k

  2 =  —  =  —————

       1       k  

7.1   Subtracting a whole from a fraction

3 + 2 • k     2k + 3

—————————  =  ——————

   k           k  

8.1       Adding fractions which have a common denominator

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

       2     2 • k

  2 =  —  =  —————

       1       k  

9.1     Pull out like factors :

 2 - 2k  =   -2 • (k - 1)

10.1    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:

-2•(k-1)

———————— • k = 0 • k

   k    

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

The equation now takes the shape :

 -2  •  (k-1)  = 0

Equations which are never true:

10.2      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

10.3      Solve  :    k-1 = 0

Add  1  to both sides of the equation :

                    k = 1

Step-by-step explanation:

Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1

Given the equation expressed as

5−k+12=16

We need to find the value of "k" that will make the equation equal

Given

5−k+12=16

Collect the like terms

17 - k = 16

Subtract 17 from both sides

17 - k - 17 = 16 - 17
k = 16 - 17
k = -1

Hence the value of k that will make the equation true is -1

Answer:

2. 4a+2c = 5000

4. a + c = 1600

Step-by-step explanation:

Answer:

2.) 4a+2c=5,000

4.) a+c=1,600

Step-by-step explanation:

4 times a(adults) plus 2 times c(children)=5,000

4 is from $4 per adult(a) and 2 is from $2 per children(c).

a+c=1,600

You can add the number of adults and children to find the answer.

Answer:

528  dollars

Step-by-step explanation:

The starting price is $600. And it goes down by 20% then comes back up 10% so steps are:

First we got 20% off so I did 100 - 20 and got 80%

1: 80%  * 600 = 80/100 * 600 = 480

Then we get an increase of 10% so I multiplied 110% with 480 which was our new price

2. 110/100 * 480 = 11 * 48(simplifying)

=  528

Answer:

question 5 = 167.5ft^3 so yeah correct

question 6 = the 4th answer = 2388ft^3

Volume  using full pi = ; 2389.2ft^3 or 2389 ft^3 to 4sf.

Step-by-step explanation:

question 6 =

We have 13 Diameter. Which is 6.5 radius

D = 13

R = 6.5

H = 18

Surface area a of cylinder pi x 6.5^2 =  132.73229

or 42.25pi

Then we just multiply by the height to get the volume.

42.25x 18 = 760.18 pi

or 132.73229 x 18 =2389.18122

Volume = 2389.2ft^3 or 2389 ft^3 to 4sf.

As the answer given is 2388ft^3 then show your pi workings as 3.14 or 3.1459

Answer:

nice question but I don't know the answer

Answer:

this is irregular shape it has four vertix and two faces

The number of vertices and faces this shape have is 4 and 4.

Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).

Vertices are points of intersections of different edges.

We are given that;

The figure

Now,

Number of vertices= 3+1

=4

Number of faces= 3+1

=4

Therefore, by vertices the answer will be 4 and 4.
