PART A :OK so here is the table for the health inspector; all you are really doing is 7+7+7, and so on:
PART A: health inspector: 7,14,21,28,35,42,49,56,63,70,77,84..........
PART A:same thing for the fire inspector, except this time your adding 12+12+12, and so on:
PART A: fire inspector: 12,24,36,48,60,72,84,96.......
PART B: and to figure out what day they will both come is you have to find the LCM (least common multiple)
PART B: which in this case is Day 84
hopes this helps!!!!!
        
             
        
        
        
Answer:
1. 208 in^2
Step-by-step explanation:
1. We can break the shape up into a rectangle in the middle and 2 triangles on either side of said rectangle.
The dimensions of the rectangle are 8 in by 20 in, and we only know one leg of the triangle as well as the hypotenuse.
If we know one leg and the hypotenuse we can use the pythagorean theormed to sovle for the other side and get 6 in. 
So we have
(8 * 20) + 2((1/2)(6)(8))
160 + 48
208 in^2
 
        
             
        
        
        
Answer:
-5
Step-by-step explanation:
You can work backwards with this problem if that helps you.  
so, what times 3 = -15
-5 times 3 = -15 so that would be the answer
 
        
                    
             
        
        
        
Answer:
Week 4
Step-by-step explanation:
Ben has $250 in the beginning.  He saves $150 per week.
y = 150x + 250
Tim has $1,650 in the beginning.  He spends $200 per week.
y = 1650 - 200x
We are trying to find which x-value produces the same y-value for both equations.  You can do this by setting both equations equal to each other.
150x + 250 = 1650 - 200x
(150x + 250) + 200x = (1650 - 200x) + 200x
350x + 250 = 1650
(350x + 250) - 250 = (1650) - 250
350x = 1400
(350x)/350 = (1400)/350
x = 4
By week 4, they will have the same amount of money.
