system : 8L+ 4S = 120

L + S = 20

There are 10 small packs and 10 large packs

step by step answer :

to form the two systems, we have to determine the catagories of the 2 equations : one for money and one for the no of packs

after forming the two equations we simply put the numbers in the same order put above on the calculator ( mode 5:1) and the calaculator will answer it in seconds . 10 small packs and 10 large packs.

To check your answer , substitute the letters with their values and if both equations gave you the same value at the end then your answer is correct!

Determine, to one decimal place, the length, width & height of the rectangular prism that would have the greatest volume, wi

Leya [2.2K]

Answer:

The length = The width = The height ≈ 5.8 cm

Step-by-step explanation:

The volume of a rectangular pyramid, V = l × w × h

The surface area of the pyramid = 2 × l × h + 2 × w × h + 2 × l × w = 200

∴ l × h + w × h + l × w = 200/2 = 100

We have that the maximum volume is given when the length, width, and height are equal and one length is not a fraction of the other. Therefore, we get;

At maximum volume, l = w = h

∴ l × h + w × h + l × w = 3·l² = 100

l² = 100/3

l = 10/√3

Therefore, the volume, v = l³ = (10/√3)³

The length = The width = The height = 10/√3 cm ≈ 5.8 cm

Lapatulllka [165]

Answer:

Max is currently 12 years old.

Step-by-step explanation:

Zeke's current age = 8 years

Lets take Max's current age as $x$ years.

Then Max's age 3 years ago = $x-3$

Double Max's age 3 years ago = $2*(x-3)$

Double Max's age 3 years ago + Zee's current age = 26

⇒ $2*(x-3)$ + $8$ = $26$

= $2*(x-3)+8=26$

= $2x-6+8=26$ (Simplifying the brackets)

= $2x+2=26$

= $2x+2-2=26-2$ $2x=24=$ $x=12$

So Max's current age is 12 years.
