The 3 inside angles of a triangle equal 180.
Add the 3 angles together to equal 180:
X + (5x-20) + 4x = 180
Simplify the left side by adding like terms:
10x-20 = 180
Add 20 to each side:
10x = 200
Divide both sides by 10:
x = 20
Angle A = x = 20
Angle B = 4X = 4(20) = 80
Angle C = 5x-20 = 5(20) -20 = 100-20 = 80
Billion gallons per day, because the independent quantity is volume of water in billion gallons and dependent quantity is time in days.
oh shi sorry I wish I could help but I'm stupid
Answer is 285
Reason
When you divide by a fraction, you flip the fraction and multiply
So 190 divided by 2/3 becomes 190 x 3/2
Factor 190 x 3/2, multiply across
190 x 3 = 570 then
570 divided by 2 = 285
From the intervals from (-2,0) and (4,7) I am not sure if you are required to use (,) or [,] but I will change my answer if needed.
Thank you!
