Step-by-step explanation:
we can factor out z
so that'll be
z((1/m)-(1/n))=1
divide by the value in parentheses on both sides
z=1/((1/m)-(1/n))
I can't tell if there's more the problem wants you to do. I could rewrite the equation on paper more easily, but I don't have one on hand
 
        
                    
             
        
        
        
RM298
reason: multiply RM4 by 10 to get RM40 and add that to RM258 to get RM298
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
In general: 
Volume = (the area of the base of the figure) times (the figure's height)
Here, the area of the base is 4 square feet, the height is 2 1/2 foot = 5/2 foot
Our Volume is then:
4 square feet * 5/2 foot = 10 cubic feet
 
        
             
        
        
        
In logarithm, inverse operations are applied.
 
 
        
        
        
Answer:
It would be D, because you have 12 students who have tickets worth n amount, and all of them get a discount of $5.00 off. You would there have 12 times the number of tickets (n) minus $5.00 off from your discount
