Answer:
-7/45
Step-by-step explanation:
First, find the lowest common denominator for 9 and 15. It's 45. Make both fractions over 45 by multiplying the top and bottom by the same number. 

 Since 15*3=45, multiply the top by 3 also.    Since 9*5=45, multiply the top by 5 also.
  Since 15*3=45, multiply the top by 3 also.    Since 9*5=45, multiply the top by 5 also.

Answer is QM = 18
You can find the length of QM by using Pythagorean theorem. See the attachment. 
It is a quadrilateral with 4 equal congruent sides. 
If SP = 30, so do the other 3 sides indicated by the tick marks on all 4 sides.
We will call side RQ = the hypotenuse 
or side “c” = 30
We know RM is leg “b” = 24
Side “a” is our unknown QM
Our formula is 
a^2 + b^2 = c^2 
a^2 + 24^2 = 30^2
a^2 + 576 = 900
a^2 = 900 - 576
a^2 = 324
Take square root of both sides to solve a
a = 18
QM = 18
 
        
        
        
Standard form: Ax + By = C
Equation: 12x + 15y = 120
