Answer:

X=8

Step-by-step explanation:

3x+5=5x-11

-3x   = -3x      Subtract the 3x from both sides

5      = 2x-11    You will end up with 5 on the left and 2x-11 on the right

+11     = +11      Add 11 to both sides to get rid of 11 on the right

16     =2x       you will end up with 16=2x

16/2=2/2       Lastly divide 2 on both sides

8=x                You will end up with the answer as x=8

What is the greatest common factor of 8m, 36m3, and 12?<br><br> 4<br> 8<br> 4m<br> 8m
lidiya [134]

The greatest common factor is exactly as it sounds: the greatest factors of two or more expressions.

Factorize the numbers and identify all common factors. To get the GCF multiply all common factors:

8m=2\cdot 2\cdot 2\cdot m,\\36m^3=2\cdot 2\cdot 3\cdot 3\cdot m\cdot m\cdot m,\\ 12=2\cdot 2\cdot 3.

Common factors are: 2 and 2, their product is 2·2=4, then the greatest common factor is 4.

olasank [31]

Answer:

Conjecture :  2xy / ( x + y ) ≤  √xy

Step-by-step explanation:

Harmonic mean of  x and y = 2xy/( x + y )

<u>Formulate a conjecture about their relative sizes </u>

we will achieve this by computing harmonic and geometric means

Geometric mean = √xy

harmonic mean = 2xy/( x + y )

Conjecture :  2xy / ( x + y ) ≤  √xy

attached below is the proof
