Zahra wants the equation below to have an infinite number of solutions when the missing number is placed in the box. _(x-3)+2x=-( x-5)+4 which number should she place in the box? 1.)–3 2.)–1 3.)1 4.)3

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
