-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.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
