Answer:
.0075 (hope this help; let me know if not)
Step-by-step explanation:
The operation is + and the signs of the numbers are opposite so we have to subtract. The bigger number has positive sign in front if so we do 1.2-1.125=1.200-1.125
I'm going to line up
 1.200
-1.125
---------
If you have 200 and you take about 125... 75 should beleft
so
 1.200
-1.125
---------
0.075
 
        
             
        
        
        
Step-by-step explanation:
The Base of the triangle= 3+6=9 units
Altitude of the triangle=6-2=4 units
Hence, Area of a triangle= Base×Altitude ×1/2
Hence, Area of the abc = 9×4×1/2=18 unit^2
 
        
             
        
        
        
Answer:
x=16
Step-by-step explanation:

40-8=32
32/2=16
x=16
 
        
                    
             
        
        
        
Answer:
The answer to your question is He must get 80%
Step-by-step explanation:
Data
Scores 55%, 78%, 84%, 93% and X
Average 80%
Process
1.- Write a equation to solve this problem
- There are five scores
Score 1 = S1 = 55
Score 2 = S2 =  78
Score 3 = S3 = 84
Score 4 = S4 = 93
Score 5 = S5 = X
Equation
                Average = (S1 + S2 + S3 + S4 + S5) / 5
- Solve for S5
                5 Average = S1 + S2 + S3 + S4 + S5
                S5 = 5 Average - S1 - S2 - S3 - S4
- Substitution
                S5 = 5(80) - 55 - 78 - 84 - 93
- Simplification
                S5 = 400 - 310
- Result
                S5 = 90
 
        
             
        
        
        
Answer:
x=8
Step-by-step explanation:
First multiply 30 and 16 to find out how many ounces are in the 30 lb. bag of dog food.
30 x 16=480
Since the 3 dogs eat 20 ounces of food, we can make a equation.
3(20x)=480
20 x 3=60
60x=480
x=8
