Copying the problem:

  5              4
--------- - ---------
3x^2y      6xy^3

1) Multiplying numerator and denominator of the first fraction by 2 results in:

   2(5)
----------  (Call this A)
6x^2*y

2) Mult. the numerator and denom of the 2nd fraction by x results in

      4x
-------------    (Call this B)
  6x^2y^3   and this denom. is almost the same as that of the 1st fract.

3) Mult. the num. and den. of fract. A by y^2 results in

  2(5)(y^2)
---------------  (Call this C)
6x^2*y^3

Now the denominators of the 2 fractions are identical, and so we can combine them:

   4x               10y^2          4x - 10y^2
------------  -  -------------- = ----------------  (answer)
6x^2*y^3      6x^2*y^3       6x^2*y^3

Ben is 140cm tall. Mike is 1090mm tall. Who is taller? how much taller?
Sati [7]
1 cm = 10 mm

Ben = 140 cm
Mike = 1090/10 = 109 cm

140 - 109 = 31
31 * 10 = 310

Ben is taller by 31 cm or 310 mm

1.
a. your answer is correct
b. 60 and  hndreths=60.08
c. 16 and 8 thousanths=16.008
d. 60 and 8 tenths=60.8
e. your answer is correct
f.  your answer is correct

2.  16.207, 6.9, 16.19, 16.26
so the greatest is obviously one of the 16's
compare
16.207, 16.190, 16.260
obviously, the order is 16.260,16.207,16.190
then the last one is 6.9 so the order is 16.26,16.207, 16.19, 6.9 and the numbers in order is 2,4,3,1

3. I can't see the puzzle that well, but 11.88 is more than 11.50 since 0.88 is more than 0.50


4.  can't see the puzzle that mmuch
hundreths is 0.0x x is the hundrreths since exg 1/100=1 hundreths=0.01


5. remember if the number is more than five round up and if less than 4 round down so
10.5, 10.6, 10.7 10.8 10.9 10.1 10.2 10.3 10.4 would work

6. tenth=0.8 so the numbers could be 17.81, 17.82 17,83

7.rembmber the decimal places and line them up so again
6.081, 6.082 6.083 and so on



8. 1/2=0.5 or 0.50000

9. the greatest decimal
first find the greatest whole number
60
then find all the 60's and read from left to right the numbers after the decimal, the biggest number to the left is bigger, if they are the same, move one place to the right and count again


10.  I can't seee the puzzzle very clearly but hte answer is pirates

Which of the following phrases can be written as the algebraic expression 76−(x+3) ?
lapo4ka [179]
The correct answer should be E, The sum of a number and three subtracted from seventy-six.

“A number” represented by x, is added to 3, and is therefore labeled a sum.
(x+3)
This sum is then subtracted from 76.
76-(x+3)

It’s B because you just rotate the triangle not the angles. Look at a regular and the opposite of the way it’s going is counterclockwise.
