Answer:
x=0
Step-by-step explanation:
−6+5x+14=8
(5x)+(−6+14)=8(Combine Like Terms)
5x+8=8
5x+8=8
Step 2: Subtract 8 from both sides.
5x+8−8=8−8
5x=0
Step 3: Divide both sides by 5.
5x
5
=
0
5
solution:
You have only two qualitatively different outcomes possible. Count
the number of ways to get each of the two.
There are just two possible outcomes here: the two missing socks
make a pair (the best case) and the two missing stocks do not make a
pair (the worst case). The total number of different outcomes (the ways
to choose the missing socks) is 10 C 2 = 45.
The number of best-case ones is 5; hence its probability is 5 /45 = 1/9
The number of worst-case ones is 45 − 5 = 40; hence its probability is 40/45 = 8/9.
On average, you should expect 4 • 1/ 9 + 3 • 8 /9 = 28/ 9 = 3 1/ 9 matching pairs.
