Answer:
x = -5
Step-by-step explanation:
Start by adding the 5x to each side of the equation to the left to get...
-25 = 5x + 25 + 5x
Then you would add 25 to each side of the equation to get...
0 = 10x + 25 + 25
Adding on, you would simplify this step to get...
0 = 10x +50
You would now have to make the x variable on one side alone so you would subtract 50 from both sides of the equation again to get...
-50 = 10x
Finally you would divide both sides of the equation by 10 to get x alone...
-50/10 = 10x/10
And simplify that to get...
x = -5

Answer:
18 students are likely to be wearing red
Step-by-step explanation:
From the question, we know a student either wears red , or blue, with the probability of a student wearing red is 3 times more probable than wearing white.
So, let’s say out of the 24 students, x of them are wearing white. What this practically mean is that 3 * x = 3x of the students would be expected to be wearing red.
Now, adding the number of people wearing red and white together in terms of x, we have x + 3x = 4x
We equate this to 24; 4x = 24 and x = 24/4; x = 6
The number wearing red probably is 3 * x = 3 * 6 = 18 people
