Answer:
Step-by-step explanation:
Let the width of the rectangle be 'w' inches
Length of the rectangle= (2w-7) inches
Area of the rectangle=
Area of the rectangle= Length*Width
Making the factors of the equation:
Taking common from the equation;
OR
As the width of the rectangle cannot be negative, so,
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:
we know that,
sum of all angles in a triangle measures 180°
Then,
x+y+60°=180°
x+y=180-60
=120°
x= 60°
y=60°
