If your math homework includes equations, inequalities, functions, polynomials, matrices this is the right trial account. Include everything above plus finding limits (lim), sums, matrices.
Solve all type of trigonometric (sin, cos, tan, sec, scs, cot) expressions, equations, inequalities. Solve integral problems - definite, indefinite integrals.
How many hectares a day would one tractor plough then?
Solution: If each of $6$ tractors ploughed $120$ hectares a day and they finished the work in $4$ days, then the whole field is: $120\cdot 6 \cdot 4 = 720 \cdot 4 = 2880$ hectares.
You can simplify and evaluate expressions, factor/multiply polynomials, combine expressions.
You can solve all problems from the basic math section plus solving simple equations, inequalities and coordinate plane problems.
When 6 tractors work together, each of them ploughs 120 hectares a day.
If two of the tractors were moved to another field, then the remaining 4 tractors could plough the same field in 5 days.
So 00 \frac\cdot x \frac \cdot (8100 - x) = 9100$ Therefore 00 \fracx \frac(8100 - x) = 9100$$\fracx = 190$$x = 3800$Therefore, the cows produced 38 litres of milk the first year, and 70$ and 30$ litres of milk the second year, respectively.
