Find the probability of picking a red marble. This would be 12 out of 20. The, take 1 away from the denominator because you already picked a marble. So then find the probability of picking white marble, which is 8 out of 19. The multiply them to get 84 out of 380

Juli2301 [7.4K]

Answer:

y= -3/5x + 12/5

Step-by-step explanation:

<u>Remember, the formula is y= mx + b</u>

#1 So we're gonna put it into that order by subtracting 3x from both sides:

3x + 5y= 12

-3x           -3x

We are left with this:

5y= -3x + 12

#2 Now we will divide 5 to both sides to isolate the variable

5y/5= -3x/5 + 12/5

#3 Now that the variable is isolated we are left with the answer:

y= -3/5x +12/5

Hope this helps :)
