4 0

Let the number = x.

So 2 times x subtracted from 11 is written as 11-2x

The result is 4 more than the number is written as 4 +x

Now you have 11-2x = 4 + x

We can now solve for x.

Add 2x to each side:

11 = 4 + 3x

Subtract 4 from each side:

7 = 3x

Divide both sides by 3:

x = 7/3

Ne4ueva [31]

55/(4+7) x 6+(15/3)= 35

  2. 5 x 6=30
  3. 30+(15/3)=35
  4. So in total it equals to 35.

<em>If a rectangular prism has a volume of 470.40 cm</em><span><em>³, and the length and width is equal to 6.4 and 9.8, we will find the height by using some inverse operations. We will use the variable h to represent height</em>

<em>Length x Width x Height = Volume</em>
<em>6.4 cm • 9.8 cm `• h = 470.40</em>

<em>470.40 ÷ (9.8 x 6.4)</em>
<em>     = 470.40 ÷ 62.72</em>
