6:12
Answer:
12
Step-by-step explanation:
sum the parts of the ratio, 2 + 4 = 6 parts
Divide total number of socks by 6 to find the value of one part of the ratio.
18 ÷ 6 = 3 ← value of 1 part of the ratio, thus
4 parts = 4 × 3 = 12 ← number of white socks

Answer:
sinθ = y/r sinθ = 
cosθ = x/r cosθ = 
tanθ = y/x tanθ = 
cscθ = r/y cscθ = 
secθ = r/x secθ = 
cotθ = x/y cotθ = 
explanation:
r = 
r = 10
x = 8
y = -6
r = 
r = 5
x = 4
y = 3

First sequence with common difference:
8-x=y-8
Second sequence:
20-y=y-x
Solving two simultaneous equations:
x=16-y
20-y=y-16+y
y=12
x=4
