Step-by-step explanation:
x+13÷2×2=4×2
x+13=8
x+13-13=8-13
x=8-13
x=-5
Answer:
the first step is wrong
it should be 4(x-4)/(x+1)(x-4) - (x+2)/(x-4)(x+1)
The answer is 3.4, you need to subtract 1.6 from 5.
P(black socks): 24/42 or 12/21
P(black socks without replacing): 23/41. As a result, the probability of randomly picking 2 black socks, without replacement, from the basket is 12/21×23/41=276/861 or 32%. Hope it help!
