Alright! To solve this one you first have to find out what 1cm is equal to in km, to do that you have to divide 18km by 3cm:
[18 ÷ 3] = 6.
Now we know that 1cm is 6km. To find how far apart they are on the map you simply divide 54km by 6km:
[54 ÷ 6] = 9.
They are 9cm apart on the map.
The pet store has 12 reptiles.
5/12 reptiles are turtles, so 5 reptiles are turtles
2/12 reptiles are snakes, so 2 reptiles are snakes
5 plus 2 is 7
12 minus 7 is 5
there are 5 lizards
5/12 of the reptiles are lizards
4[(3(-2) - 6] / (1 +(-2))
= 4(-12) / -1
= 48
answer
<span>B. 48 </span>
D. no solution
Because they never found each other, the point they cross on is the solution.
