Answer:
First blank- 32000 ounces
Second blank- 2000 pounds
Yes the bridge can hold 1 ton. 
Step-by-step explanation:
The ratio of the scale of the model to the real bridge = 1:4
The test model shows the model can take 8000 ounces
The real bridge will therefore take 8000 x 4 = 32000 ounces
16 ounces = 1 pound
32000 ounces =  x pounds
==>  = 32000/16 = 2000 pounds
2000 pounds = 1 ton
therefore the bridge holds 1 ton 
 
        
                    
             
        
        
        
Answer:
24
Step-by-step explanation:
3x+6=30
Get the co-efficient by itself
3x +6=30
      -6.   -6
3x=24
Divide by 3 on both sides
24/3
x =8
