Answer:

x = 5.153846154

Step-by-step explanation:

Simplifying

6x + 31 = 19x + -36

Reorder the terms:

31 + 6x = 19x + -36

Reorder the terms:

31 + 6x = -36 + 19x

Solving

31 + 6x = -36 + 19x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-19x' to each side of the equation.

31 + 6x + -19x = -36 + 19x + -19x

Combine like terms: 6x + -19x = -13x

31 + -13x = -36 + 19x + -19x

Combine like terms: 19x + -19x = 0

31 + -13x = -36 + 0

31 + -13x = -36

Add '-31' to each side of the equation.

31 + -31 + -13x = -36 + -31

Combine like terms: 31 + -31 = 0

0 + -13x = -36 + -31

-13x = -36 + -31

Combine like terms: -36 + -31 = -67

-13x = -67

Divide each side by '-13'.

x = 5.153846154

Simplifying

x = 5.153846154

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.

Papessa [141]

Answer:

$\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}$

Step-by-step explanation:

Given dimensions of the box = 20cm × 6cm × 4cm .

Dimension of the cube = 2cm × 2cm × 2cm .

Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,

$\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}$

$\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }$

<h3>Hence the number of cubes that can be fitted in the box is 60 .</h3>
