20 and 28 can be divided by 4, so just take the 4 out so the answer should be 4(5x - 7)
        
                    
             
        
        
        
Answer:
67
Step-by-step explanation:
A linear pair is two angles which form a straight angle when combined (or 180 degrees). Thus do 180 - 113 to get 67 degrees for Angle 2
 
        
             
        
        
        
Answer:
   Erie to Rochester is 145 miles
Step-by-step explanation:
If we designate the points of interest as C, E, and R, we are told that ...
   CE + ER = CR . . . . . the various distances are segments of a straight line
For CE = 94 and CR = 239, we can fill in the given information and solve for ER.
   94 + ER = 239
   ER = 239 -94 . . . . . . subtract 94 from both sides of the equation
   ER = 145
The distance from Erie to Rochester is 145 miles.
 
        
             
        
        
        
The answer is 3 square units
        
             
        
        
        
3y  = 5x + 30
y + 5x = 50 .......(1)
3y - 5x = 30 .....(2)        - rearranging the first equation.
Add (1) and (2):-
4y = 80
y = 20  
Now plug y = 20 into equation (1):-
20 + 5x = 50
5x = 30 
x = 6
The 2 numbers are 6 and 20.
