Answer
8
Step-by-step explanation:
104 - 8, and then divide 96 by 12 equals 8
1/3= 5/15
2/5= 6/15
5/15 + 6/15 = 11/15
15/15 - 11/15 = 4/15
Part C= 4/15
Given:



To find:
The value of a and PQ.
Solution:
We have,

(CPCTC)
So,


Isolating variable terms, we get


Divide both sides by -2.


Now,




Therefore, the value of a is 8 and the value of PQ is 28.
3/5n+9/10=-1/5n-23/10
+1/5 +1/5
4/5n+9/10=-23/10
-9/10 -9/10
4/5n=-32/10
divide 4/5 on both sides
n=-4
