Answer:
Step-by-step explanation:
Set the equations equal to each other: 25x+45=15x+14
Solve for x: 10x = -31
Solve for x: x=-3.1
Plug the x value back into one of the equations to find the value of y:
y = 15 (-3.1) +14
y = -32.5

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
