Answer:
-The equation r+b-33 represents the total number of marbles
-There 9 black marbles
-There are 24 red marbles
Step-by-step explanation:
The bag contains 33 red and black marbles. Let the number of black marbles be b and that of red marble to r
Total number of marbles will be
b+r = 33 i.e b+r-33 = 0... (1)
If the number of red marbles is 6 more than double the number of black marbles, this can be represented as;
r = 6+ 2b... (2)
Substituting 2 in eqn 1 we have;
b + 6+2b = 33
3b = 27
b = 9
r = 33-9
r = 24
This shows that there are 9 black marbles, 24 red marbles and the equation r+b-33 represents the total number of marbles in the bag.

Answer:
Your answer would be the 60th
Step-by-step explanation:
This is your solution due to the fact that when you find the multiples of 12 and 30 you will realize that that's the first number they meet at, let me show you.
Multiples of 12 - 12, 24, 36, 48, 60
Multiples of 30 - 30, 60, 90, 120, 150
So The Least Common Denominator is 60!
Thus that is how I know that the 60th customer at the movie theater would get both items for free.
Hope This Helped!
i think it would be your first choice
Answer:
r≈4.51yd
Step-by-step explanation:
The surface area of a sphere is given by the formula SA = 4r2, where r is the radius of the sphere. If the surface area of a sphere is 256 square yards, then the radius of the sphere is 4.51yd.
Formula: A=4πr^2
