Just subtract the top from the other equation like the 3rd one 9/3-1/6=8/3 <span />
X - the number of loads by land carriers,
y - the number of loads by air carriers;
The system of inequalities:
x + y ≤ 150
2,000 x + 1,250 y ≤ 180,000
Answer:
93.75 Kg
Step-by-step explanation:
Farmer spreads 25 kg fertilizer over an area of 4000 m square .
So, Over 1 m square ,
kg of fertilizer will be needed
As we know , 1 hectare = 10,000 m square.
So, 1.5 hectare equals 15,000 m square.
So, for 15,000 m square , Fertilizer needed will be equal to
×15,000 = 93.75 Kg
So, 93.75 Kg of fertilizer is needed for 1.5 ha of land.
The nearest thousand is 547,000
