Answer:
I think it will be combined and simplified
Ok so the first step would be to distribute 3 into 3x and -6. So 3 times 3x would be 9x. 3 times -6 is -18.
the equation now is
18 = 9x - 18
Now you would have to do inverse operation
18 = 9x - 18
+18 +18
36 = 9x
Now you would divide 9x into 36 to isolate the variable
36 / 9x = 4
x = 4
From the table, the speed of Corinne is given by

From the graph, the speed of Aretha is given by

The distance from the starting point of Corinne at any time t is given by D = 0.125t while the distance from the starting point of Aretha at any time t is given by D = 3.5 + 0.1t
Let t be the number of minutes after the start of the race when Corinne catchs Aretha, then
0.125t = 3.5 + 0.1t
0.025t = 3.5
t = 3.5 / 0.025 = 140
Therefore, the number of <span>minutes after the start of the race that Corinne will catch Aretha</span> is 140 minutes.
The ratio of yellow to total is 2 to 8, or 1:4 if you divide both by 2. So the answer is B.
