The answer for the problem is the option C, which is: <span>C. Angle Bisector Theorem.
The explanation is shown below:
By definition, a bisector of a angle is the line that bisects an angle, or in other words, it is a line that passes through a vertex and cut it into two angles that have the same measure. Keeping this on mind, if a point is located on </span><span>the bisector of an angle, then this point is equidistant from the two sides of the angle, this means that the distance between the point and the two sides are equal.</span>
<span>1/5(2x-15) + (3/5)x = 4 1/4
</span><span>x*2/5 - 15/5 + x*3/5 = 4 1/4
</span><span>x*2/5 - 3 + x*3/5 = 4 1/4
</span><span>x*(2/5+3/5) - 3 = 4 1/4
</span><span>x*(5/5) - 3 = 4 1/4
</span>1*x - 3 = 4 1/4
<span>x= 4 1/4 + 3
</span><span>x= 7 1/4 </span>
The thing that can’t be together is the -3x
Answer:
117mph
Step-by-step explanation:
Given that
Total number of stations= 3
Total average time of journey of train = 65
total stop time at three stations = 3×2 =6 min
Total distance between stops = 115 miles
as we can see
Total time train was travelling = 65- 6 =59 min
so, average speed of train can be calculated as:
Average Speed = 
Average Speed = 
To convert this speed into miles per hour (mph) multiply the above speed by 60
Average speed = 60×1.95 =117 mph
So the average speed of train is 117mph.
You wont because 72 +21+15+36+69+81+9+27+42+63=435 and 435 is greater than 100
