Answer:
y= 15
Step-by-step explanation:
Y= Kxz
y=6  x=1/2   z=6
15= K (1/2) (6)
15= K (3)
K= 5
SO 
y= (5) (1/2) (6)
Y= 15
 
        
                    
             
        
        
        
<span>The number sentence 4x7=(4x3)+(4x4) is an example of distributive property. 
The distributive property states the following:
</span><span>a × (b + c) = a × b + a × c
</span>Multiplying <span>a sum by a number is the same as </span>multiplying<span> each addend by the number and then adding the products. </span>
In our case, a=4 b+c=7, b=3, c=4
        
                    
             
        
        
        
Step-by-step explanation:
there is no diagram so I'm just going to guess this however
sin x = 6/9
sin x = 2/3
sin x = 0.67
x = sin inverse of 0.67
x = 42.1
 
        
             
        
        
        
3-8 equals to -5 because if you stele a number line and count 8 points from three it will equal -5
