Answer:
27.86 or 27 wholes 6/7
Step-by-step explanation:
Let the number be x
140% of x = 39
140x/100 = 39
140x = 3900
x= 3900/140
x = 27 wholes 6/7 or 27.86
Answer:
Step-by-step explanation:
If the polynomial is a cubic (third-degree), then it is
f(x) = x³+4x²-27x+40
and the other root is 2+i.
However, if we need two additional roots, it implies that the polynomial is a quartic (fourth degree). In that case, we need additional information. Reread the original question and update post if necessary.
C= total $ cost
n= number of pizzas purchased
x= $ cost per pizza
C= x * n
C= xn
If you know the cost per pizza and the number of pizzas purchased, plug those numbers in the equation above to find the total cost.
EXAMPLE: If each pizza cost $10 and 5 were purchased, the equation would be: C= ($10)(5)= $50 total
ANSWER: C= xn
