Answer:
 b = 55 degrees
Step-by-step explanation:
The angles 30, a, b and 45 must sum up to 180 degrees
Subtracting (30 + 45) from both sides leaves us with a + b = 105 degrees.
But b = a + 5.  Substituting a + 5 in the equation above yields
a + a + 5 = 105 degrees, so that
2a = 100 degrees, and a = 50 degrees.  Then b = a + 5, or b = 55 degrees.
 
        
             
        
        
        
Answer: 0
 
Step-by-step explanation:
Since m is with x, you don't need to care about y
We would get 2x - 6x + 4x = mx
0x = mx
m is 0
 
        
             
        
        
        
Answer:
(p • 10) - (p • 2)
Step-by-step explanation:
To be doubly sure of your answer, do the actual mult.:
p(10-2) = 10p - 2p.  This is equivalent to (p • 10) - (p • 2) (Answer D).

3(x+5)=39
3 * x + 3 * 5 = 39
3x + 15 = 39
3x = 39 - 15
3x= 24
x = 8
