Answer:
(3x + 10) / (2x + 5)(x - 5).
Step-by-step explanation:
(3/2x+5) + (5/x-5)
= [3(x - 5) + 5(2x + 5) ] / [ (2x + 5)(x - 5)]
= 3x - 15 + 10x + 25 / (2x + 5)(x - 5)
= 13x + 10 / (2x + 5)(x - 5).
660 ft/min equals 11 ft/sec

Answer:
72 km/h
Step-by-step explanation:
We need to convert units
so:
20 m ----- 1 km -------- 3600 s
1 s ----- 1000 m ----1 h
and solve ot
20 x 1 x 3600 s = 72000 we multiply numerators
1s x 1000 m x 1 h = 1000 we multiply denominators
we divide de results 72000/1000 = 72
