<span>D: a and b are odd that should be the answer </span>
Answer:
Step-by-step explanation:
So a diver went 25.65 ft BELOW so it's negative.
then he went 16.5 ft further down, so that's negative also.
he then rose 12.45 ft, so that's positive.
so the expression is: -25.65+-16.5+12.45, the answer is 23.7
The answer is <span>one halfn − 16
</span>
Let the number be n.
<span>One half of a number is (1/2n)
</span><span>decreased by 16 is (-16)
</span><span>one half of a number decreased by 16 is
1/2n - 16
Or </span><span>one halfn − 16</span>
