It is the Identity Property of Addition
The identity property of addition is that the sum of any number and its identity value gives the same number as the result. Also, 0 is the identity element.
Answer:
p(picking red)= 4/12 (4 over 12) which can get simplified to 1/3 (1 over 3)
Company A: y = 50x + 15
Company B: y = 130x + 55
Set the equations equal to each other and solve for x (number of weeks).
50x + 15 = 130x + 55
Subtract 50x from both sides:
15 = 80x + 55
Subtract 55 from both sides:
-40 = 80x
Did you have a typo? The companies will never have the same cost because company B costs so much more and weeks cannot be negative.

Answer:
Step-by-step explanation:
Total Students = 28
Brown Hair = 22
NOT Brown Hair = 28 - 22 = 6
The probability of an event is the number of that event divided by total number.
So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:
P(NOT BROWN) = 6/28
Reducing, we get:
P(NOT BROWN) = 3/14
