A restaurant offers a $12 dinner special that has 7 choices for an appetizer, choices for an entrée, and 3 choices for a dessert. How many different meals are available when you select an appetizer, an entrée, and a dessert?

21x,

where x = number of entrees

Step-by-step explanation:

appetizer choices: 7

choices for an entree: x

choice for dessert: 3

Total number of combinations:

7 * x * 3 = 21x

Since the number of choices of entrees is missing, the best answer you can get is 21x, where x is the number of entrees.

Replace x with the number of entrees to get your final answer.

answer: i think it is (1,-2)

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
