The difference of a number divided by 3 and 9 is equal to 8 .

1 answer:

8 0

<span>two divided by the difference of a number and 3 minus 4 divided by a number plus 3, equals 8 times the reciprocal of the difference of the number squared and 9.

let x=number
2/(x-3)-4/(x+3)=8/(x^2-9)=8/(x+3)(x-3)

LCD: (x+3)(x-3)
2(x+3)-4(x-3)=8
2x+6-4x+12=8
-2x+18=8
-2x=-10
x=5</span>

Who knows what pi(3.14)x-99.29?

MrMuchimi

Answer:

Pi also appears in the calculations to determine the area of an ellipse and in finding the radius, surface area, and volume of a sphere.

Step-by-step explanation:

The number represented by pi (π) is used in calculations whenever something round (or nearly so) is involved, such as for circles, spheres, cylinders, cones, and ellipses. Its value is necessary to compute many important quantities about these shapes, such as understanding the relationship between a circle’s radius and its circumference and area (circumference=2πr; area=πr²).

Our world contains many round and near-round objects; finding the exact value of pi helps us build, manufacture, and work with them more accurately.
