If last year Deon biked b miles and this year he biked 580 miles, then the total number of miles he biked over the two years is the sum of the miles from each year. Therefore, the expression for the total number of miles Deon biked is:
\( b + 580 \) miles
This expression simply adds the unspecified number of miles biked last year (b) to the 580 miles biked this year to get the total.
last year, deon biked b miles. this year he biked 580 miles. using b write an expression for the total number of miles he biked
