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

miv72 [106K]
They all have to have common denominators

The common denominator is 32

3/4= multiply by 8/8= 23/32

3/16= multiply by 2/2= 6/32

11/32. Is. 11/32

1/8 multiply by 4/4 =. 4/32

Smallest to greatest is 1/8. 3/16. 11/32. 3/4

Jimmy's cedar trunk is in the shape of a rectangular prism and has a volume of 3/4 cubic yard. How many cubic blocks with a side
gizmo_the_mogwai [7]

Answer: 6 blocks

Step-by-step explanation:

Given

Volume of the rectangular prism is V=\dfrac{3}{4}\ yd^3

Length of the cubic block is a=\dfrac{1}{2}\ yd

Volume of each cubic block is

\Rightarrow V_o=\left (\dfrac{1}{2}\right)^3\\\\\Rightarrow V_o=\dfrac{1}{8}\ yd^3

Suppose, n blocks are required to measure the volume of Prism

\Rightarrow V=nV_o\\\\\Rightarrow \dfrac{3}{4}=n\cdot \dfrac{1}{8}\\\\\Rightarrow n=\dfrac{3\times 8}{4}\\\\\Rightarrow n=6\ \text{blocks}

Thus, 6 blocks are required to measure the volume of prism.
