What is the probability that a randomly thrown dart that lands within the rectangle lands within a shaded region? all of the circles are congruent, and the diameter of each circle is 100 cm. a. 39/200 b. 49/250 c. 98/125 d. 157/200

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

wouldn't that be a) 1

4=4x then divide 4 on both sides and you get x=1
