Answer:
x = 17
Step-by-step explanation:
∠6 and ∠7 are vertically opposite angles and thus are congruent, hence
4x = 2x + 34 ( subtract 2x from both sides )
2x = 34 ( divide both sides by 2 )
x = 17
<ABC = 10 and BD is the angle bisector of <ABC
so AD = DC
Plug in
3y + 6 = 5y - 18
-2y = -24
y = 12
Answer
y = 12
PS. In case you need to find x
<ABC = 10 and BD is the angle bisector of <ABC
<ABD = <DBC
3x - 1 = 34 - 2x
5x = 35
x = 7
The reason why the sum of your probabilities equals 0.5 is because you're only considering half of the problem--i.e. the probabilities for only one gender. For example, the probability that there are only three children and all are boys is 1/8. But, remember, it could be the case that there are three children and all are girls. Thus, the probability that there are three children is 1/4--not 1/8. Thus, multiply your result for P(X=4) and P(X=5) by 2 and you should end up with the right answer...

Step-by-step explanation:
Answer:
f = 12(s - 35).
Step-by-step explanation:
The number of miles per hour he was over the limit = s - 35.
So his fine f is:
f = 12(s - 35).
