The absolute value of x is simply x and followed by the expression.
X + 1 + x + 1 <_ 2
2x + 2 <_ 2
2x <_ 0
X <_ 0
Basically all values that follow this inequality will most likely hold true.
For instance. -1.
-1 + 1 = 0
Absolute value of -2 = 2.
2 is equal to 2. This expression holds true.
3 1/2= 3.5 inches and 4 2/3 feet is 56 inches. Now put 3.5/56=0.0625
Nathan= 1/10 of the job per day
Matt= 1/15 of the job per day
3/30 + 2/30. =5/30
1/(5/30) = 30/5. Or 6 days for both working together.
