Answer:
30 miles
Step-by-step explanation:
Let d represent the distance to the island. The relation between time, speed, and distance is ...
time = distance/speed
so the total time for the round trip is ...
d/15 +d/10 = 5
Multiplying by 30, we get
2d +3d = 150
d = 150/5 = 30
The island was 30 miles from the harbor.
The answer would be C) y</=x-14
The steps to get this are:
1) Add 5y to both sides to remove the negative 5y
2) Subtract 70 from both sides to isolate 5y
3) Divide everything by 5 to simplify
That's how to get the answer. Hope this helps
.5 because first you add 1 on each side, that gets rid of the 1 on the left. then divide by 4
