Answer:
Elga is 42 years old
Step-by-step explanation:
55-13=42
The answer is C. 64 teachers.
14 x 64= 896
so 1 x 64= 64
The percentage of vehicles passing through this construction zone that are traveling at a speed of 50 and 57 miles per hour
X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)
