First set up your two equations:
x + y = 90
x = 2y - 30
Then substitute what x equals in the second equation into the first equation:
(2y -30) + y = 90
Now solve for y:
3y -30 = 90
3y = 120
y = 40
Then use y = 40 and substitute the value for y into one of your original equations and solve for x. I'll choose the first one, but either one will work.
x+ 40 = 90
x = 50
So your solution is x = 50 and y = 40
The expression representing the distance is

Answer:
11
Step-by-step explanation:
I just assumed D is the midpoint; and if D is the midpoint,
GD=DH, GD+DH=GH
5.5+5.5=11

Answer:
The probability that he or she is a male or a civilian employee is 1.037068
Step-by-step explanation:
Probability of sworn officers = 0.696
Probability of civilians = 1 - 0.696 = 0.304
Probability of male sworn officers = 0.882*0.696 = 0.6139
Probability of male civilian = (0.304*(1-0.608)) = 0.1192
Hence probability that he or she is a male or civilian employee is
0.6139 + 0.1192 + 0.304 = 1.037068
