Agricultural

Last year, the Agro agricultural company sowed wheat on a total area of 29 ha and rye on a total area of 18 ha. From all these fields, it harvested a combined total of 137.4 tonnes of grain. The sum of the average yields per hectare of wheat and rye was 5.8 tonnes. How many tonnes of wheat and how many tonnes of rye did the Agro company produce in total?

Final Answer:

a =  87 t
b =  50.4 t

Step-by-step explanation:

m=137.4 t S1=29 ha S2=18 ha p=5.8 t/ha  a+b=m a/S1+b/S2=p a+b=137.4 a/29+b/18=5.8  a+b=137.4 18a+29b=3027.6  Pivot:Row1Row2  Row2181 Row1Row2 0.61b=30.8  b=0.6111111130.8=50.4 a=183027.629b=183027.629 50.4=87=87 t  a=87 b=5252=50.4
