Answer:
A
Step-by-step explanation:
You should approach this problem by plugging the answer choices into the equation, since there are only four that you need to do. A works because 8-8 = -7(-1+1) which are both equal to 0

For each subset it can either contain or not contain an element. For each element, there are 2 possibilities. Multiplying these together we get 27 or 128 subsets. For generalisation the total number of subsets of a set containing n elements is 2 to the power n.
Answer: 16g - 25h
4 (-6g - 10h) + 3h - 4 (- 3h - 10g)
-24g - 40h +3h +12h +40g
16g - 25h
Step-by-step explanation:
if this is wrong im sorry
4,120 pounds ← error = 6 lbs
<span>4,100 pounds ← error = 26 lbs </span>
<span>4,200.34 pounds ← error = 74.34 lbs </span>
<span>4,500.765 pounds ← error = 374.765 lbs</span>
Answer:
red marbles
Step-by-step explanation:
Since the formula is;
Probability = number of required outcome
_______________________
number of possible outcome
3/8. = x/56
8x. = 168
x. 21 ( number of blue marbles)
Therefore if the total marbles = 56 and 21 of the marbles are blue then to get the red marbles
= 56 - 21
= 35
