An example of a linear equation with three variables, x, y, and z, is given by: ax + by + cz + d = 0, where a, b, c, and d are constants and a, b, and c are non-zero. Linear equations occur frequently in most subareas of mathematics and especially in applied mathematics.
One study has shown that tea tree oil is more active against the organisms associated with transient carriage than against commensal skin flora and thus may be useful in eliminating the transient flora while suppressing but maintaining commensal flora. 21 The rapid kill rate of Clone 88 compared with standard tea tree oil shown for most of the organisms tested in the present study is encouraging and suggests that further clinical studies should be carried out.
Tea tree oil is used for treating scabies because it is believed to contain antibacterial and anti-fungal properties, which help people to fight and rise against the evil of scabies using this method. The most common process of treating scabies with tea tree oil is by bathing in water containing a few drops of oil. About 10 ml of tea tree oil is sufficient for a bathtub half filled with warm water.
