First, change everything into minutes.
12 noon is 12 by 60 which = 720 minutes.
9am is 9 by 12 which = 540 minutes.
X is now your number of minutes before noon.So noon - x is the next step:
720 - x
20 minutes ago it was 720 - x - 20
720 - x - 20= 540 + 3x (3x because you're looking for 3 times as many minutes)
720 - 20 - 540=4x (you combine all the like numbers and variables)
160 = 4x
160/4= x
40 = x
Your answer is 40 minutes

Step-by-step explanation:
Answer:
2X^2+5/2X-3/2=0
Step-by-step explanation:
To identify the equation use the following method
(X-a)(X-b)=0
Put values
a=-4
b=3/2
(X+4)(X-3/2)=0
X^2+4X-3/2X-3/2=0
X^2+(8X-3X)/2-3/2=0
X^2+5/2X-3/2=0
