Use proportions because we know that the triangles are similar.

Cross multiply.
20x=28×5
x=7
answer: 7
Answer:
Take an example, say :- 55.67
In this, first split the number into 2 parts - part before the decimal point & the part after the decimal point.
So,
55 is read as - fifty five
Decimal point is read as - point
67 is read as - six seven (not sixty seven)
So, 55.67 is read as - fifty five point six seven.

y=x+5 this the the answer
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
