<h3>30 tiles need to buy for same cost in both store.</h3>
Step-by-step explanation:
Let x be the number of tiles to buy for same cost in both store.
18+0.69 · n = 1.29 · n,
1.29n -0.69n =18 or
0.6n =18
n =18/0.6=30

Answer:
The coast guard craft will get to the distressed boat the fastest.
Step-by-step explanation:
The coordinates of boat are (57,64).
The coordinates of rescue boat are (67,83).
The coordinates of coast guard craft are (65,46).
Both rescue crafts travel at the same rate. One of them will get to the distressed boat the faster, whose distance from the boat is least.
Distance formula:

The distance between boat and rescue boat is

The distance between boat and coast guard craft is

Since the distance between boat and coast guard craft is least, therefore coast guard craft will get to the distressed boat the fastest.
Well 66 is 66 and 2/3 is 66.6 repeating so 66 <span />
