Speed = distance / time
Speed = 50 miles / 4 hours
Speed = 12.5 miles per hour
1. Add 5 to both sides. So x=5. That is a vertical line. The answer is undefined
2. 25- 5 7/8 + 6 1/2
Denominators have to be the same
Multiply 1/2 by 4/4
25-5 7/8 + 6 4/8
25 - 11 11/8
23 16/8- 11 11/8
12 5/8
7² + 10² = c² where c = hypotenuse
49 + 100 = c²
149 = c²
c = √149 feet
