Aakesh has two bags of marbles. The first bag contains 6 red marbles, 4 blue
Orlov [11]

The answer for the 1st bag is option B = 1/3

The answer for the 2nd bag is option C = 5/9

Number of marbles in 1st bag - 15 (6 red, 4 blue & 5 green)

Number of marbles in 2nd bag - 9 (3 red, 1 blue & 5 green)

The formula of probability = Total number of events in the outcome /total number of outcomes.

Now the probability that Aakesh will select a green marble from the 1st bag is 5(green marbles)/15(total number of marbles in 1st bag)

That is 5/15=1/3

Now the probability that Aakesh will select a green marble from the 2nd bag is 5(green marbles)/9(total number of marbles in 1st bag)

That is 5/9

What would be the equation and how can I solve it
Blababa [14]
If alonzo is x then the equation is

x + (x +3) + 2(x + 3) = 57

Which equals

x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12

This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old

Answer = 15 years old

Answer:

Not enough info

Step-by-step explanation:

Find the length from the school to the community center (this is the shortest route).

2^2+7^2 = c^2

c = sqrt(53)

The amount of time the trip takes depends on how long it takes Miguel to walk one city block.

sqrt(53)*lengthOfTimeForOneCityBlockInMinutes = the minimum time.
