Justin is 2 years older than one third Marcella's age. Aimee is is four years younger than 2 times Justin's age. Define a variable and write an expression to represent Justin's age. Then find Justin's age and Aimee's age is Marcella is 63 years old.

M x 1/3 + 2. The variable is Marcella's age. If Marcella is 63, one third of her age is 21 so 21+2 = Justin is 23. Aimee is 23x2-4 so she is 62 years old.

Step-by-step explanation:

answer: option a.

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
