Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.
I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...
-2/30 + -5/30 = -7/30
 
        
             
        
        
        
Answer: 
Step 1: Multiply 1x5 Step 2: Multiply 2x3 Step 3: Add the two products 
d=v*t
d=distance 
v=velocity(speed)
t=time
distance is equal to the product of velocity and time, equation form;
d=vt

A straight line is 180°. So you can do:
(15x - 4) + (5x - 8) = 180  Simplify
20x - 12 = 180
20x = 192    Find the value of x
x = 9.6
m∠ABD = 15x - 4      Plug in x = 9.6
m∠ABD = 15(9.6) - 4 = 144 - 4 = 140°
m∠DBC = 5x - 8   Plug in 9.6
m∠DBC = 5(9.6) - 8 = 48 - 8 = 40°
