1. A in some part is correct, but the triangles are indeed correct, and the argument is for HL, so the answer is C
2. Are congruent by SSS (both shares a side).
X=205
y=41
You come across these answers by making an equation or system of equations based on the word problem given. 1. x+y=246 and 2. x÷y=5 . The you would multiply by y on both sides and get x=5y . Then you would substitute for x in the first equation and get (5y)+y=246 . Then you would get 6y=246 . Them you would divide by 6 on both sides and get y=246÷6 . Then you would get y=41. Then you would plug the y value into the first equation. You would get that x+(41)= 246, subtract on both sides and get x=246-41, then you would get an answer of x=205.
C
Step-by-step explanation:
Just got it right
Answer:
Right answer is B) x>-10 and x<10
While going to the ice
skating rink,
Rosario drives a distance of 55 miles in = 1 hour
Then
While going to the
ice skating rink,
Rosario
drives a distance of
120 miles in = (1/55) * 120
<span> = 2.18 hours</span>
The number of miles
per hour Rosario averages while coming back home = x
Total up and down
time taken by Rosario = 2.75 hours
Then time taken by
Rosario to come
back
home from ice
skating rink = (2.75 – 2.18) hours
<span> =
0.57 hours</span>
Then we can write
the equation as
x = 120/0.57
miles/hour
<span>
= 210.53 miles/hour</span>
<span>So the average speed
of Rosario while coming back home from ice skating rink is 210.53 miles per
hour.</span>
