To simplify the expression (3/2r + 3r + 7), we need to combine like terms and then express the answer as a single fraction in simplest form.
First, let's combine the terms with 'r'. We have (3/2r + 3r). To add these terms, we need to find a common denominator. In this case, the common denominator is '2r'.
(3/2r + 3r) = (3/2r) + (3r * 2/2) = (3/2r) + (6r/2) = (3 + 6r)/(2r)
Now, let's add the final term '7' to the expression. Since it doesn't have any variables, we can write it as (7/1).
(3 + 6r)/(2r) + 7/1 = (3 + 6r)/(2r) + (7 * 2r)/(1 * 2r) = (3 + 6r + 14r)/(2r) = (20r + 3)/(2r)
Therefore, the simplified expression is (20r + 3)/(2r)
3/2r+3r+7
= (3/2)r + 3r + 7
= (3/2)r + (6/2)r + 14/27
= (9r + 14)/2
