Answer:
As such, in first quadrant, both the coordinates (x and y) are positive and both are negative in third quadrant. In second quadrant, y is positive and x is negative, while in fourth quadrant x is positive and y is negative, As (-4, -2) has both x and y coordinates negative, it will be found in third quadrant
Step-by-step explanation:
Answer:
the first option is the right answer.
Answer:
Step-by-step explanation:
ppppppppppppppppppppppppppjjjjjyoooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
let x =the number
Step-by-step explanation:
81+x=3x-39
group like terms
81+39=3x-x
120=2x
120/2=2x/2
60=x
therefore x =60
Alright, lets get started.
3 feet = 1 yard
If we cube both sides of the equation, we will get the conversion into cubic yards
So,

27 cubic feet = 1 cubic yards
So, 1 cubic feet =
cubic yards
So, 360 cubic feet =
cubic yards
So, 360 cubic feet = 13.33 cubic yards
13.33 cubic yards of air can it circulate per minute. : Answer
Hope it will help :)
