Value of a = 3
Value of a + b = 3 + (-2/3)
Value of a + b = 2 1/3
Difference = 3 - 2 1/3
Difference = 2/3
-------------------------------------------------
Answer: They are 2/3 unit apart
--------------------------------------------------
Supplementary angles - Sum = 180°
X + Y = 180°
x = larger angle
y = smaller angle
x = 2y - 60
x + y = 180
x = 180 - y
2y - 60 = 180 - y
2y - 60 -180 + y
3y = 240
y = 80°
x+y = 180
x+80° = 180°
x = 100°

The question is incomplete, the complete question is;
If in 0.5 min the tank gets 0.8 gallons of the water then
how many gallons will be in 1 min ?
how many gallons will be in 3 min?
and how long it takes for 40 gallons?
Answer:
1.6 gallons
4.8 gallons
25 mins
Step-by-step explanation:
This question has to do with proportion.
If it takes 0.5 mins for the tank to get 0.8 gallons
in 1 minute the tank will get 0.8 * 1/0.5 = 1.6 gallons
In 3 minutes the tank will get 3 * 1.6 gallons = 4.8 gallons
if it takes 1 min to get 1.6 gallons
it will take x mins to get 40 gallons
x = 1 * 40/1.6 = 25 mins
Parallel never cross
perpendicular is a 90 degree angle
its neither if its not 90 degree or never crossing
