Answer 2

Let's solve the equation step by step to find the value of "y."

The equation is: 3 1/4 + 1/2y + 1 1/3 + 5/6y = 5 11/12

First, let's convert the mixed numbers into improper fractions: 3 1/4 = (43 + 1)/4 = 13/4 1 1/3 = (31 + 1)/3 = 4/3

Now, the equation becomes: 13/4 + 1/2y + 4/3 + 5/6y = 5 11/12

Next, we need to combine like terms: 1/2y + 5/6y = (1/2 + 5/6)y = (3/6 + 5/6)y = 8/6y = 4/3y

So the equation now becomes: 13/4 + 4/3y + 4/3 = 5 11/12

Now, let's get rid of the fractions by multiplying all terms by 12 (the least common multiple of 4, 3, and 6):

12 * (13/4) + 12 * (4/3y) + 12 * (4/3) = 12 * (5 11/12)

This simplifies to: 39 + 4y + 16 = 71

Now, let's solve for "y": 4y + 55 = 71 4y = 71 - 55 4y = 16 y = 16 / 4 y = 4

So, the value of "y" that satisfies the equation is y = 4.

Now, let's address the second part of your message. It seems you mentioned "40 points" without specifying what it pertains to. If you could provide more context or clarify, I'd be happy to assist further!
