Step-by-step explanation:
There are 21 socks in total. Only 7 of them are white.
When you pick your 1st sock, you have a 7/21 chance to get white.
When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.
So the probability to get a pair of white socks is 2/21.

Answer:
50 ° corresponds to 10cm
so
360° corresponds to 10/50 x 360
= 72 cm
Answer:
2.25, 2, 4.75 I am not sure if it is correct tho
Step-by-step explanation:
the frist row shows 5 6 so basically it would be r = y + 1 (red paint being r and yellow paint being y)
1.25 + 1 + 2.25
3 - 1 = 2
3.75 + 1 = 4.75
and for part be may I know the options?
Answer:
∠ 3 = 55°
Step-by-step explanation:
∠ 2 and ∠ 7 are corresponding angles and are congruent, then
5x - 60 = 3x + 14 ( subtract 3x from both sides )
2x - 60 = 14 ( add 60 to both sides )
2x = 74 ( divide both sides by 2 )
x = 37
∠ 2 = 3x + 14 = 3(37) + 14 = 111 + 14 = 125°
∠ 2 and ∠ 3 are adjacent angles on a straight line and sum to 180° , so
125° + ∠ 3 = 180° ( subtract 125° from both sides )
∠ 3 = 55°
