Answer:
The probability that the result of the spin is green and the coin lands tails up : 
Step-by-step explanation:
As
the spinner has following three colors:
Also
the coin has two sides which are:
As the sample space is:
{red - head; red - tail; green - head; green - tail; yellow - head; yellow - tail}
So different colors with coin sides can be combined in total
ways.
Therefore, the probability that the result of the spin is green and the coin lands tails up : 
<span>(b+3)/7=(b-3)/6
6(b+3) = 7 (b-3)....> cross multiply
6b + 18 = 7b -21 ...>distributive property
6b - 7b = -21 -18 ...>subtract 7b to both sides then simplify
-b = -39 ...> multiply -1 to both sides
b = 39</span>
Answer:
i think
Step-by-step explanation:
There are 8 black socks and 20 white socks. 5 socks times 4 = 20 white socks, and 2 socks times 4 = 8 black socks. So, Pa has 8 black socks.
.65x=39
x=39/.65=60 just solve it as algebra
