1 serving of Roast beef and 2 servings of mashed potatoes.
The Answer to this question is X= -10
4.5(8-x)+36=102-2.5(3x+24)
36-4.5x+36=102-7.5x-60
72-4.5x=42-7.5x
-4.5+7.5x=42-72
8x=30
x=-10
Hope this Helps and There the Work that got you the answer
Answer:
39,916,800ways
Step-by-step explanation:
This arrangement is permutation. Since it is a circular arrangement, the formula for calculating arrangement of objects sitting in a circular path is (n-1)! where n is the number of objects. Applying this formula in the question, the 12 students will sit in a circle in (12-1)! ways.
(12-1)! = 11!
= 11×10×9×8×7×6×5×4×3×2×1
= 39,916,800ways
I think neither of these proportions are right... are you sure you wrote it down correctly?
Polynomials are classified according to their number of terms. 4x3 +3y + 3x2 has three terms, -12zy has 1 term, and 15 - x2 has two terms. As already mentioned, a polynomial with 1 term is a monomial. A polynomial with two terms is a binomial, and a polynomial with three terms is a trinomial.
