There are different ways to express an algebraic expression equivalently, but here are three possible options:
(3a + 30)/5: This expression is obtained by factoring out a common factor of 3 from both terms in the original expression and then dividing by 5.
3/5(a + 10): This expression is obtained by distributing the factor of 3/5 over the sum of a and 10.
6/10a + 12: This expression is obtained by simplifying the fraction 3/5 to 6/10 and then factoring out a common factor of 2 from both terms in the resulting expression.
