Step-by-step explanation:
Answer:
3/12 or 1/4 after simplifying
Step-by-step explanation:
3 chances of getting green because there are 3 green and there is a total of 12 marbles so 3 out of 12, which is equal to one fourth.
To solve this, we combine like terms. Our equation becomes:
-2u + 13 = -5
Now to subtract both sides by 13 to find that:
-2u = -18
Finally, we divide both sides by the coefficient and find that:
u = 9
