Answer 2

Answer: The required simplified form is 3.5r - 7.

Step-by-step explanation: We are given to simplify the following expression :

`E=6.4r-7-2.9r~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

To simplify the given expression, we must combine the like terms, that is, the terms involving r.

From expression (i), we get

`E\\\\=6.4r-7-2.9r\\\\=(6.4-2.9)r-7\\\\=3.5r-7.`

Thus, the required simplified form is 3.5r - 7.
