The answer is 15! Because 5x3 is 15
Distance = 475 time = 9.5 hrs since distance and time varies directly therefore in 9.5 hrs train travels 475 miles => In 1 hr train travels 475 / 9.5 miles = 50 miles and in 4 hrs train travells 50*4 i.e 200 miles

Y=-3x+5
y=-8x+25
-3x+5=-8x+25
-20=-5x
x=4
y=-3(4)+5=-7

Step-by-step explanation:
<u>Triangles And Circles</u>
If a right triangle is inscribed in a circle (or the circle is circumscribed around the right triangle), then the hypotenuse of the triangle is the diameter of the circle.
The right triangle has both legs of known lengths, thus the hypotenuse (the diameter of the circle is):
Since 50=2*25:
Thus the radius of the circle is:
