Answer:
x = 27
Step-by-step explanation:
this problem is similar to a scale drawing where we can set up a proportion:
'x' is to 5 as 162 is to 30
x/5 = 162/30
cross-multiply:
30x = 810
x = 810/30
x = 27

Answer:</h3>
Your selection is correct: 180 hours
<h3>
Step-by-step explanation:</h3>
The pool is apparently 18000 gallons (= 60 gal/h × 300 h). The combined flow from the two hoses is ...
... (40 gal/h) + (60 gal/h) = 100 gal/h
So, the time required with the two hoses is ...
... 18000 gal/(100 gal/h) = 180 h
