Isolate the variable by subtracting 8x from both sides to get -4x = -1. multiply both sides by -1 to get 4x = 1. divide both sides by 4 to get x = 1/4.
Answer: can choose 1 of 3 entrees, 1 of 5 main courses and 1 of 2 desserts.
Step-by-step explanation:
She can choose entrees in 3 ways, the main course in 5 ways and dessert in 2 ways.
Now we just need to multiply these numbers so that we get all the possible combinations.
# of ways = 3 x 5 x 2 = 30
She can choose a three-course meal in 30 ways

Answer:
The area of circle A is 16 times the area of circle B.
Step-by-step explanation:
he area of circle A is three times the area of circle B.
It depends on the value of π.
It depends on the actual diameters of the circles.
The area of circle A is 16 times the area of circle
the circumference of a circle = 2 x pi x r
Let imagine that the radius of B is 2cm
then the circumference of B = 2 x 2 x pi = 4pi
If the circumference of a is 4 times that of B, it means the circumference is 16 and the radius is 8
Area of a circle is pi x r^2
Area of B = pi x 2^2 = 4pi
Area of A = pi x 8^2 = 64pi
64/4 = 16 pi
