Answer:
x = -4
Step-by-step explanation:
Six times a number plus 3 equals three times the same number minus
nine. This equation is 6x + 3 = 3x -9. Next, solve this equation and you get -4. Plug in -4 for x and you should get -21 on both sides.

Answer:
discrete
Step-by-step explanation:
"The number of (anything)" means the possible values are counting numbers. The random variable involved is necessarily discrete.
Step-by-step explanation:
9.2 + 7.8 = 17 > 2.1
7.8+2.1= 9.9> 9.2
9.2+2.1= 11.3 > 7.8
Since, sum of any two sides is greater than the third side, a triangle can have these lengths
11/66 = n/27
We're essentially just trying to get "n" by itself :)
Big numbers may scare you, so simply simplify 11/66 into 1/6 :)
So, our new question looks like this :
1/6 = n/27
Multiply both sides by 27 :)
1/6 × 27 = n
Simplify.
27/6 = n
Simplify.
n = 4 3/6
Simplify.
n = 4 1/2

The area of any circle is (pi) x (the radius squared).
If a circle's radius is 9, then the area is (pi) x (9 squared) = 81 pi .
81 pi is around 250. None of the choices listed is anywhere close to 250.
