We have ( 5x+16 + 8x + 4 - 4x -2 )/3 = (9x + 18) / 3 = 9( x + 2 ) / 3 = 3( x + 2 ) = 3x + 6;

Answer:

The answer is 3x+6

Step-by-step explanation:

Arithmetic mean of those three values can be found into 2 steps:

All values need to be added
Total value need to be divided to total number of values

$avg=((5x+16)+(8x+4)+(-4x-2))/3=(9x+18)/3=3x+6$

The answer is 3x+6

What dose this equal (8.5)x(-3)=a

Nana76 [90]

Answer:

-25.5

8x3=24

but we still have the .5 so we multiply that by 3 which equals to 1.5 add that to 24 which makes 25.5 and because only one of the numbers was negative it turns 25.5 into -25.5.

Write √ 3 x √ 6 in the form b √2 where b is an integer.

tigry1 [53]

Answer:

Step-by-step explanation:

The catch here is to break up sqrt(6) into 2 parts that use primes to define sqrt(6)

sqrt(3)* sqrt(6)

sqrt(6) can be broken up into sqrt(2*3) which equals sqrt(2)*sqrt(3)

sqrt(3)*sqrt(2)(sqrt(3)

sqrt(3)*sqrt(3)*sqrt(2)

3*sqrt(2)
