Answer:

-2y + 2

Step-by-step explanation:

Let's first remove the parentheses.  (x - y + 1) becomes x - y + 1 and -(x + y - 1) becomes -x -y + 1.   Combine like terms:

x - y + 1 - x - y + 1 = -2y + 2

Jake walks a mile to work. If Jake has already walked two-fifths of a mile, how many more feet must he walk to get to work?
Alexxx [7]
1 mile is equal to 5280 feet.

5/5 - 2/5 = 3/5 of a mile left to walk

3/5m * 5280 ft/1m = (3m*5280ft)/(5*1m) = 15840ft/5 = 3158 feet left to walk to get to work. 

Or
5280 feet / 5 = 1056 ft * 2 = 2112 ft walked to get to work
5280 - 2112 = 3168 feet left to walk to get to work.
