Please help. -9x+12x=3(2-x)

Mathematics
1 answer:
Orlov [11]2 years ago
4 0

Answer: x = 1

Step-by-step explanation:

-9x+12x=3(2-x)

Multiply 3 by 2 and -x

-9x+12x=6-3x

Add 12x to -9x

3x=6-3x

Add 3x to both sides

6x=6

Divide 6 on both sides

Final Answer: x= 1

What is the surface area of a sphere with a circumference of 100T? Leave
mixer [17]

Answer:

10000π units²

Step-by-step explanation:

From the question given above, the following data were obtained:

Circumference (C) = 100π

Surface Area of sphere (SA) =?

Next, we shall determine the radius. This can be obtained as follow:

Circumference (C) = 100π

Radius (r) =?

C = 2πr

100π = 2πr

Divide both side by 2π

r = 100π / 2π

r = 50 units

Finally, we shall determine the surface area of the sphere. This can be obtained as follow:

Radius (r) = 50 units

Surface Area of sphere (SA) =?

SA = 4πr²

SA = 4 × π × 50²

SA = 4 × π × 2500

SA = 10000π units²

Therefore, the surface area of the sphere is 10000π units²
