Her niece sees 15 goats.
Step-by-step explanation:
Given,
Total animals on barn = 40
Total legs counted by May's niece = 110
A goat has 4 legs and chicken has 2 legs.
Let,
x represent the number of goats
y represent the number of chicken
x+y=40 Eqn 1
4x+2y=110 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 2
Putting y = 25 in Eqn 1
Her niece sees 15 goats.

Divide 357 by 40!?
It is written as 16-3 because it is 16 subtract 3 not 3 subtract 16 because that would come out to a negative integer.
Answer:
Step-by-step explanation:
Long division:
Step 1:
We divide '3x²' by 'x' to get the first term of quotient.
⇒
Now, we multiply '3x' to
⇒
Now, we subtract from the given numerator . This gives,
Step 2:
We divide the first term of the above result by 'x' again to get the second term of the quotient.
⇒
Now, we multiply '-5' to
⇒
Now, we subtract from the result obtained at the last of step 1 . This gives,
So, we stop division as we got a constant after subtraction. The constant is called the remainder and here the remainder is 0.
The quotient is our answer:
