Answer:
6 sets
Step-by-step explanation:
(“of”=multiply)
Step 1.
1/5 of 45 sets = 45 x 1/5 = 9 sets.
Step2.
2/3 of 9 sets = 9 x 2/3 = 6 sets
Final Answer:
6 sets
The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. The standard form of quadratic equation is ax2 + bx + c = 0. Upon substitution, we can easily determine the discriminant. If disc. is zero, the roots are equal; if <0, then the roots are positive and non-identical; if <0, the roots are negative and imaginary.
4d + 9 - d - 8 = (4d - d) + (9 - 8) = d(4 - 1) + 1 = 3d + 1
Answer:
The system cannot be solved by a unique cost for each soldier, because has infinite solutions
Step-by-step explanation:
Let
x-------> the cost of a legionary per day
y-------> the cost of an archer per day
we know that
------> equation A
------> equation B
Multiply equation B by 
both sides
------->
so
equation A and equation B is the same equation
therefore
This is a consistent dependent system
The system has infinite solutions
