Let the number of red marbles be r. Now we can write the equation:
Rearranging the above equation and simplifying gives the quadratic:
which factorizes to:
(r - 4)(r + 3) = 0
Therefore r = 4. there are 4 RED marbles in the bag.
Answer:
We can just work backwards to find the value of x.
If 3 * x = 23,
then x = 23 / 3
and 23 / 3 = 7.6 reoccurring.
Step-by-step explanation:
Hope this helps:)
Here is the answer
