Answer: 2x</h3>
Explanation:
Each person is x years old. Adding those unknown ages gets us x+x = 2x

Kristin jogs 48 miles in 50 minutes, so her unit rate is 48miles/50 minutes
Answer:
2 nd one
Step-by-step explanation:
Let v = number of video's she bought
Let c = number of CD's she bought
v+c=16
1495v+1688c=9355
Multiply both sides of (1) by 1495
and subtract (1) from (2)
-1495v-1495c=-8970
193c=386
c=2h
