Answer:
x = 13
Step-by-step explanation:
y=50
50 = 5x - 15
50 + 15 = 5x
65 = 5x
65/5 = 5x/5
13 = x

12.24
68+12.24=$80.24
Answer:
160 miles
Step-by-step explanation:
Distance = speed × time
Speed 1 = 40miles/hr , speed 2 = 50 miles/hr
Time 1 = 3 hrs, time 2 = 4 hrs
Distance 1 = speed 1 × time 1
= 40× 3 = 120 miles
Distance 2 = speed 2 × time 2
= 50 × 4 = 200 miles
Average distance = (distance 1+distance 2 ) ÷ 2
Distance = (200+120) ÷ 2 = 320 ÷2
= 160 miles

Answer:
4 mi/h
Step-by-step explanation:
The distance between the cyclists is the hypotenuse of an isosceles right triangle. The hypotenuse is √2 times the length of the legs in such a triangle, so each cyclist must have ridden 8 miles in 2 hours.
Their speed is (8 mi)/(2 h) = 4 mi/h.
_____
<em>Additional comment</em>
Consider an isosceles right triangle with leg lengths 1. Then the Pythagorean theorem tells us the length of the hypotenuse is ...
c² = a² +b² . . . square of hypotenuse is sum of squares of legs
c² = 1² +1² . . . . both legs are 1 in our example triangle
c² = 2
c = √2
That is, the hypotenuse is √2 times the leg length.
