Answer:

8r.

Step-by-step explanation:

If we substitute 3 into all of these equations, we get

8(3) which equals 24

6(3) which equals 18

9(3) which equals 27

7(3) which equals 21

8r is the one that equals 24 when 3 is substituted.

Answer:

Step-by-step explanation:

Put the equation in the form ax+by+c=0:

y\sqrt{3} =8x+\sqrt{3} \\=>8x-\sqrt{3} y+\sqrt{3} =0

Check the solutions:

(0,-1):

8(0)-\sqrt{3} (-1)+\sqrt{3} =2\sqrt{3}

So this is not a solution.

((\sqrt{3} ,9):

8\sqrt{3} -9\sqrt{3} +\sqrt{3} =0

So this is a solution

Radda [10]
To make this situation easier to understand, you must simplify these fractions.  3/6 is equal to 0.5
6/6 is equal to 1
4/6 is equal to 0.3333 repeating.

With this info we can tell that Gina's sailboat went to longest distant in the fifteen minutes.

Hope this helps! :)
