The second year, miles were completed. How many more of highway need to be completed Form We will let x = the number of of highway that need to be completed. We now translate the words of the problem into an equation. + + + Solve 2.46 + 4.95 + = 12.77 + x = 12.77 7.41 + x = = 12.77 = 7.41 x = State The number of miles of highway that need to be completed is Check Add: 2.46 + 4.95 /12.77 The result checks.

12.77

2.46

4.95

How many more?
12.77 - 2.46 - 4.95

5.36 ---> fourth answer

-----------------------------------------------------------

x = the number of "miles" of highway...

2.46 + 4.95 + x = 12.77

7.41 + x = 12.77

7.41 + x - 7.41 = 12.77 - 7.41

x = 5.36
