Final answer:
To evaluate the expression -|a+b|/2-c when a=1 2/3 , b=-1 , and c=-3, we substitute the given values into the equation and simplify step by step. The final answer is 17/6.
Step-by-step explanation:
To evaluate the expression -|a+b|/2-c when a=1 2/3 , b=-1 , and c=-3, we substitute the given values into the equation:
-|1 2/3 + (-1)|/2 - (-3)
First, we simplify the expression inside the absolute value:
-|4/3 - 1|/2 - (-3)
Next, we subtract the fractions:
-|1/3|/2 + 3
Since the absolute value of 1/3 is 1/3, the expression becomes:
-1/3/2 + 3
Finally, we divide 1/3 by 2, which gives us:
-1/6 + 3
Combining the fractions, we have:
-1/6 + 3 = 17/6
So, the value of -|a+b|/2-c is 17/6.
