Common Difference d = 3

The probability that Gina randomly selected two red marbles is 1/19
<u>Explanation:</u>
Total number of marbles = 7 + 5 + 8
= 20
The probability of getting two red marbles in the fraction form is given as:
P(first red marble) = number of red marbles / total number of marbles
P(first red marble) = 
P(second red marble) = number of red marbles after 1 white marble is removed / total number of marbles after 1 red marble is removed.
P(first red marble) = 
P(two red marbles) = P(first) X P(second)
= 
= 
Therefore, the probability that Gina randomly selected two red marbles is 1/19
If you are trying to solve for x, then
4x+5<=13
subtract both sides by 5
4x<=8
then divide both sides by 4
x<=2
230% in the simplest form is 2.3
