So as there are 9 reds, you know that the total number of counters is 100 (because red probability is 9/100)
so you can work out x by writing an equation.
9 + 3x + x - 5 + 2x = 100
from here you can add up all of the x's and the numbers (so you have 3x+x +2x = 6x)(and for numbers you have 9 and -5, 9 - 5 = 4) so putting these together you have 6x and 4 you get the following:
6x + 4 = 100
take away 4 from both sides
6x = 96
divide both sides by 6
x =96/6 = 16
green is x-5 so if you substitute the result we got for x...
16-5 = 11. so there are 11 greens
therefore the probability would be 11/100 as there are 100 counters overall.

Answer:
The 36 guests will be needing 15 liters of soda
Step-by-step explanation:
In this question, we are told we need 5 liters of soda for every 12 guests that are at a party. Now, we have 36 guests attending the party and we need to calculate the amount of soda in liters that we will be needing.
From the first statement, we need 5 liters for 12 guests, this means each of the guest would need 5/12 liters or let’s just say 5/12 liters/guest
Now, we have 36 guests, the amount in liters needed will be 5/12 * 36 = 15 liters
3(x-2)>-3
x-2>-1
x>-1+2
x>1
Hope my answer helped u :)
