Thanks, Rom.....

Here's another proceedure that always works, BUT....it may NOT produce a fraction in "reduced" form....however...if you are good at reducing "final" fractions....it relieves you of the task of finding the "common denominator"

Note....suppose that we have

  a    -    c

__        __

 b          d

Reduce any fractions that we can, first

Ctross multiply  in this order    ⇒   ad    and  bc    

Seperate these with the same sign as we have between the fractions

So we have   ad  -  bc

Put this over the product of the denominators  =  bd

So..we have

ad  -  bc

______

   bd

So...in your problem, we have

2       -       3

__           ___

5               3y

Note that the second fraction can be reduced first... so we have

2     -       1

__         ___

5             y   

Cross-multiply in the specified order

2*y  - 5*1     =      2y - 5

Product of the denominators  

5 * y    =   5y

So  we have

2y - 5

______       [ which is the same thing as Rom's 4th step  !! ]

   5y

Ah....you shoulda' stayed on that cruise, Sincerelyrose....sounds WAY more exciting than this math stuff!!!

1+5=18

2+10=36

3+15=54

4+20= ?

Notice.....here's one possibility.....

1(13) + 5  =  18

2(13) + 10 =  36

3(13) + 15  = 54

4(13) + 20 = 72

Need to see a pic, bambam.....  

No prob !!!

In 3 seconds, the distance that the unicycle travels =

2 revs * distance traveled per rev  =

2   * 2pi (9)  =  36 pi   inches

So...in 1 second  it travels  1/3 of this =    36 pi / 3    =   12 pi inches / sec ≈ 37.7 inches / sec

Thanks, EP.....

It might look like this :

Good, Synth....and you  ???

Can' t say.....maybe someone else on here has some experience with it....

Yep.....we've done whole homework assignments on here....[ but we may ignore them, too ]

LOL!!!.....you are definitely NOT the first....!!!

First one

Hyp = sqrt ( 9^2 + 6^2)  = sqrt ( 81 + 36)  =  sqrt ( 117) = sqrt ( 13 * 9) = 3sqrt (13) cm

Second

Leg  =  sqrt (29^2  - 21^2 )  = sqrt ( 841 - 441)  = sqrt (400)  =  20 ft
