Answer:
The answer to this is False, False, True.
Step-by-step explanation:
A is false because WAU is an obstute angle, which can't be 55 degree.
B is flase because YAU is actually the angle that is 55 degree, not 35 degree.
C is true because WAX is congruent to YAU and it is 55 degree.
To start, note that an hour is 60 minutes long. A 1/2 hour, or half hour, is then 60/2=30 minutes. Therefore, when we have 11 hours and 30 minutes, we have 11 and a half hours. Adding 3 and a half to that, we get 11.5+3.5=15 (a half can also be expressed as .5, although it's not typically done that way when expressing time - it just might be easier to visualize it this way). Therefore, we are 15 hours into the day. However, we can't just stop there - we have to account for AM and PM. Therefore, we subtract 12 hours from 15. If the number is positive, we are in PM - otherwise, we're in AM. Therefore, as 15-12=3, the time is in PM. The remaining number is the time, so Bill leaves at 3 PM. If we are left with a decimal (e.g. 3.25), we would keep the 3 and multiply the 0.25 (the decimal) by 60 to figure out how many minutes we have, so 3.25 would turn into 3+0.25*60=3:15.

Answer:
If:
(1)
And we have to rewrite the following expresion in terms of
:
(2)
Firstly we have to rearrange the right side of equation (2) in terms of
, factorizing by the common factor:
Then, we can substitute
by
:
And set it equal to zero:
>>>>This is the resulting equation
Now, each term of an algebraic expresion (like the equation above) is composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
In this case, the variable is
and the number that multiplies the variable (the coefficient) is
, whereas the constant (which is the term with no variable) is 
It's really just knowing how to use fractions.
Say you have 8 jelly beans in a baggie. 5 are yellow and 3 are green.
What is the likelihood of pulling a green one out? Not likely.
What is the likelihood of pulling out a white one out? Impossible.
