Raven has a bag of 33 red and black marbles. The number of red marbles is 6 more than double the number of black marbles.

Letr represent the number of red marbles and b represent the number of black marbles. Which statements about the marbles

are true? Check all that apply.

The equation r+b-33 represents the total number of marbles.

The equation r - 26+6 can be used to find the number of red marbles.

The equation - 26+6 represents the total number of marbles.

The equation r+33 can be used to find the number of red marbles.

There are 9 red marbles in the bag.

There are 9 black marbles in the bag.

There are 24 black marbles in the bag.

There are 24 red marbles in the bag.

-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.

it should be a and d. lmk if i'm wrong xd

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
