I believe it's A but it's not exactly clear
Answer:
(a) 9 buildings
(b) 2^n -1
Step-by-step explanation:
The number of distinct non-empty subsets of b objects is 2^b -1. Since the subsets are distinct, each could represent a list of the buildings, from the set of b buildings, in which a student is taking courses.
(a) For 8 buildings, 2^8 -1 = 255 students could enroll. for 9 buildings, 2^9-1 = 511 students could enroll.
For 500 students, 9 buildings are required.
__
(b) The maximum number of students for n buildings is ...
2^n -1
Answer:
an organism killing another organism for food
Answer:
No Solution
Step-by-step explanation:
12x + 3 = 72x + 5
subtract 12x from both sides
end up with
3 = 72x - 12x + 5
subtract 12x to 72x
3 = 60x + 5
-5 from both sides
-8 = 60x
since x is a bigger number the answer would be NO SOLUTION
12x + 3 = 72x + 5
I do not understand lins logic
x + 6 = 7x + 10
subtract 6 from both sides
x = 7x + 4
move 7x to the other side
7x = 4
divide 7
x = 0.5
Also wrong because I get how lin got that answer
My way
12x + 3 = 72x + 5
-12 x from both sides
3 = 60x + 5
+5 to other side
8 = 60x
if the x was on the other side it would make sense
but it is not so the Answer is NO SOLUTION
Hope this Helped :)
