Answer:
10.6 kg
Step-by-step explanation:
first convert 4 4/10 to kg
4/10 is equal to .4
so 4.4kg were rotten
subtract from total
15-4.4=10.6 kg
 
        
             
        
        
        
Substitute the first equation into the second equation. You will get:
4x - (2x - 5) = 7
Distribute the negative sign into the parenthesis:
4x - 2x + 5 = 7
Simplify
2x + 5 = 7
Subtract 5 on both sides
2x = 2
x = 1
Now, substitute x = 1 into the first equation:
y = 2(1) - 5
y = 2 - 5
y = -3
The solution to the system of equations is (1, -3).
