For 7A)
The sum of -4 can not be both positive as from the set of rules (+)(+) can only make postive and -4 is decleared as negative

The reasonable answer to this would be two different numbers
It could be negative and positive
Or positive and negative

<em><u>Answer:</u></em>
145.309
<em><u>Step-by-step explanation:</u></em>
So we want to find the midpoint of the two number: 145.809 and 144.809, what we want to do it to find the difference between the two numbers and then divide it by 2 so we can find the halfway point:
145.809 - 144.809 = 1
^ So from this, we just have to add half of 1 or 0.5 to the smaller number:
144.809 + 0.5 = 145.309
Answer:
-1/2
Step-by-step explanation:
Add 12 to both sides 8b=-4
Divide by 8 on both sides b=-4/8
Simplify b=-1/2
