5 days food for 150 students suggests there was 750 day rations
If there was 100 students this would last 750/100 = 7.5 days.
If it ran out after 4 days there were 750/4 = 187 students (187.5 not valid)
        
             
        
        
        
Answer:
Angle ADC = 58 degrees
Step-by-step explanation:
Since it is a right angle...
(-6x + 2) + (-4x + 38) = 90
-10x + 40 = 90
-10x = 50
x = -5 ---- > -4(-5) + 38 ---> 20+38 ---> 58
