Since each day 3 miles of the road is being added, we can simply multiply the number 33 by 3, getting 99. If the road started with 59 miles, we need to add 59 to 99, getting 158 miles.
5. the equation looks like: ((2x+1)+4)/((x)+4)= 5/3 then you do cross multiplication and get: 6x+3+12=5x+20 subtract 5x on each side. subrtract the 3 and 12 from the 20. and you get your answer 5=x
