Answer:

Step-by-step explanation:
Given: 
To solve for y, let us first isolate y on one side of the equation. We can do this by subtracting
from the left and move it to the right. We then get:

Now, we have y isolated. We now have to remove the 4 from the y. The only way to do this is divide both sides by 4. We then get our final answer:

We can clean this up by putting it in a common form, slope-intercept form:

2 3/8 - 1 7/8
Change to improper fractions
19/8 - 15/8 = 4/8 = 1/2
the probability that more than 87 students will pass their college placement exam is 0.9616.
5/12
we use pythag to find the missing side length
hope this helps :D
