Had to look for the missing details and here is my answer:
The inequality that is being referred here is this: <span>18x+12y<=250.
Now, based on this inequality, I can say that the ordered pair (4,3) represents </span><span>Kalila purchases 4 tickets, 3 of which are youth tickets. If we try to plug in the values, this is what we get:
18(4) + 12(3) <=250
72 + 36 <=250
108 <=250
And this is correct. 108 is less than or equal to 250. Hope this helps.</span>
Answer:
When ordering three or more fractions from least to greatest, compare two fractions at a time. It is helpful to write a number in a circle next to each fraction to compare them more easily.
Work: -4y+3=19
Subtract 3 on both sides.
-4y=16
Divide -4 by -4 on both sides
y= -4
