Step-by-step explanation:
<em>We must simplify each option to see if they are equivalent to
.</em>
<em>Lets try A.</em>
can be simplified to
by dividing both the numerator and denominator by 3.
÷ 
A is correct!
<em>Lets try B</em>
simplifies to
. However, because this answer is not negative, it is not equivalent.
<em>Lets try C</em>
There is a negative in the numerator, making this fraction negative. So yes,
.
- Bonus Info: If there was a negative in both the numerator and denominator, the two negatives would cancel eachother out, making the fraction positive
C is correct!
<em>Lastly, Lets try D</em>

can be simplified by dividing by 3 to
.
÷3 = 
D is correct!

<u>y = 25</u>
Step-by-step explanation:
<u>=> 115 = y + 90 {exterior angle of triangle is equal to the sum of its opposite two interior angles}</u>
<u>=> 115 = y + 90 </u>
<u>=> 115-90 =y</u>
<u>=> 115 = y + 90</u>
<u>=> 115-90 =</u><u>y</u>
<u>=> y = 25</u>
