Answer:
x = -9/2
Step-by-step explanation:
1. Divide 9 by -1/3:
÷ 
= · 
= -27
2. Divide both sides by 2:
2(x - 9) = -27
(x - 9) = 
3. Add 9 to both sides:
x = 
(or 4.5 if you need it in decimal form)

Problem A
Usually the number of bits in a byte is 8 or 16 or 32 and recently 64. You don't have to write a formula to restrict it to this number of bits. You are not asked to do so. The general formula is 2^n - 1 for the problem of Millie and her golden keys. Somehow the system can be made to choose the right number of bits. Apple IIe s for example, used 8 bits and there was a location that told the processor that fact.
2^n - 1 <<<<< Answer
Problem B
In this case n = 4
2^n - 1 = 2^4 - 1 = 16 - 1 = 15
Millie can collect 15 keys <<<<<< Answer
You have to divide negative fifty-six by eight to get the charge on each particle. So you do -56/8. Which gives you negative seven as the answer.
Answer = -7
Answer:
D. 29
Step-by-step explanation:
180 - 151 = 29
Answer: B. perpendicular lines because they intersect at a right angle, making them perpendicular.
