Question

If (8 ÷ m) + 4 = 20 , what is the
value of m?

Answer 1

m = 1/2 = 0,5

Explanation:

`(8)/(m) +4=20`

`\Leftrightarrow (8)/(m) =20-4`

`\Leftrightarrow (8)/(m)= 16`

`\Leftrightarrow (8)/(m) * m= 16* m`

`\Leftrightarrow 16m = 8`

`\Leftrightarrow m = (8)/(16)`

`\Leftrightarrow m=(8 * 1)/(8 * 2)`

`\boxed{m=(1)/(2)}`
