Given:
95 pink rubber bands
90 brown rubber bands
185 rubber bands in all.
Probability of pink : 95/185 ⇒ 19/37
95 ÷ 5 = 19
185 ÷ 5 = 37
Probability of brown : 90/185 ⇒ 18/37
90 ÷ 5 = 18
185 ÷ 5 = 37
The answer is c because you need to isolate the x

Step-by-step explanation:
Answer: explanation below
Explanation: The triangle sum property states that a triangle’s angles always add up to 180 degrees. Whether or not the triangle is acute, obtuse, or right, all of its three angles always add up to 180 degrees.
Find the total distance between the two runners:
5.1 + 4.1 = 9.2 km apart.
We want to calculate the distance each runner does:
Runner A distance = X km, rate = 8.5 km/ hr.
Time = X / 8.5
Runner B distance = (9.2 - x) Total distance between the runners minus what runner A runs equals where they meet).
Rate = 7.4 km/hr.
Time = (9.2-x) / 7.4
Now to find where they meet set the two equations equal:
x / 8.5 = (9.2-x) / 7.4
Cross Multiply:
7.4x = 78.2 - 8.5x
Add 8.5x to both sides:
15.9x = 78.2
Divide both sides by 15.9:
x = 78.2 / 15.9
x = 4.918 = 4.9 km.
Since X is the distance runner A runs, subtract that from his distance from the flag pole:
5.1 - 4.9 = 0.2
The runners meet 0.2 km west of the flag pole.
