Answer:
56
Step-by-step explanation:
Hey There!
so this is a parallelogram so opposite angles are congruent
So basically what i am saying is that angle P is congruent to angle R
So we need to solve for x
We know that angle P and angle Q are supplements meaning that they will add up to 180 
so we setup the equation 

step 1 combine like terms

now we have 
180=11x-7
step 2 add 7 to each side 
180+7=187
-7+7 cancels out 
now we have 
187=11x
step 2 divide each side by 11
187/11=17
x=17
now we plug in 17 to (3x+5) to get the value of angle R
17x3=51
51+5=56
therefore m∠R = 56
 
        
             
        
        
        
Answer:
A repeating decimal is a decimal with no end, its constantly repeating itself
A terminating decimal is a decimal with an end
 
        
             
        
        
        
-3(x+5)=-9
-3x-15=-9
 +15 +15
-3x=6
-1x=2
1x=-2
x=-2
