x-10=x/2

Simplify both sides of the equation.

x−10 = x /2

x+-10 = 1/2 x

x-10 = 1/2 x

Subtract 1/2 x from both sides.

x-10-1/2 x = 1/2 x - 1/2 x

1/2 x-10 = 0

Add 10 to both sides.

1/2 x-10+10 = 0+10

1/2 x = 10

Multiply both sides by 2.

2*(1/2 x) = (2)*(10)

Your answer should be: x = 20

Use the image below to describe at least three different ratios, written in simplest form. Include at least one part-to-part rat
9966 [12]

The different ratios are 2 : 7, 2 : 9 and 7 : 9

<h3>How to determine the ratio?</h3>

The statement is given as:

8 out of 36 squares unfilled

This means that:

  • There are 36 squares
  • 8 are unfilled
  • 28 are filled

The part-to-part ratio is represented as:

Ratio = Unfilled : Filled

This gives

Unfilled : Filled = 8 : 28

Simplify

Unfilled : Filled = 2 : 7

The part-to-whole ratios are represented as:

Ratio = Unfilled : Total

Ratio = Filled : Total

So, we have:

Unfilled : Total = 8 : 36

Filled : Total = 28 : 36

Simplify

Unfilled : Total = 2 : 9

Filled : Total = 7 : 9

Hence, the different ratios are 2 : 7, 2 : 9 and 7 : 9
