The function <span>6x^3 - 5y^2 is a C. binomial because there are 2 terms, and the prefix "bi" means 2.</span>
What would make finding the answer a bit easier, is converting them into improper fractions. You would turn that first fraction to
and the second fraction to
. (You are dividing a negative by a negative, therefore, your answer would be a positive.
Let's follow the procedure of keeping, switching, and flipping. You keep the first improper fraction, switch the division sign to a multiplication sign, and flip the second fraction. That would make it :
×
.
You multiply the 9 and the 2, you get 18. You multiply the 3 and the 4, you get 12. That makes it
. This, converted to a mixed fraction, makes 1
., which is the same as 1
. Your answer is the
SECOND CHOICE.
Answer:
Number of ducks = 37
Number of pigs = 18
Step-by-step explanation:
Let,
x be the number of ducks
y be the number of pigs
According to given statement;
x+y=55 Eqn 1
2x+4y=146 Eqn 2 (As ducks will have 2 legs and pigs will have 4)
Multiplying Eqn 1 by 2
2(x+y=55)
2x+2y=110 Eqn 3
Subtracting Eqn 3 from Eqn 2
(2x+4y)-(2x+2y)=146-110
2x+4y-2x-2y=36
2y=36
Dividing both sides by 2
Putting y=18 in Eqn 1
x+18=55
x = 55-18
x = 37
Hence,
Number of ducks = 37
Number of pigs = 18
