Work Step by Step
Original expression: $1.1+(7d+0.1)$ Combine like terms. 1.1 and 0.1 are the only terms we can combine because there are no other like terms in the expression. $1.1+0.1=1.2$ The expression should now look like this: $1.2+7d$ It is impossible to simplify this further because all like terms have already been combined. So your final, simplified answer is $1.2+7d$.
