Answer:
a) Micheal's present age = 8 years old
b) The sum of their ages in 6 years time = 63 years.
Step-by-step explanation:
From the above question, we know that 
Rui feng is 3 years old 
We are told that 
• Michael is 5 years old than Rui feng 
Micheal's present age is calculated as:
= 5 + Rui feng's age
= 5 + 3 = 8 years
• Vishal is thrice as old as Micheal
Vishal's present age is calculated as
= 3(Micheal age)
 = 3(8)
= 24 years.
The sum of their ages in six years time 
= ( 3 + 6) +( 8 + 6) + ( 24 + 6)
= 18 + 15 + 30
= 63 years 
Therefore, a) Micheal's present age = 8 years old
b) The sum of their ages in 6 years time = 63 years.
 
        
             
        
        
        
Answer:
Damian swam, ran, and raced his bike for a grand total of 35.30 miles
Step-by-step explanation:
15.01+12.4= 27.41 miles
27.41+7.89= 35.30 miles
 
        
             
        
        
        
Cross multiply
2x(3x-4) = 3(x+2)
5x - 8x = 3x + 6 
-3x= 3x+6
x = 6

Answer:
y = -1/2 - 12
Step-by-step explanation:
The inverse function of y= 2x -12 would be y = -1/2x-12
So if its positive ex(5) and it ask for the inverse that would be - 1/5 
You put a 1 on top and make it negative
