We can use a variable equation to solve this. Let A represent alan's age, B represent bob's age, and C represent Cindy's age. So Bob's age would be Alan's age - 5, or a -5 = B. Then Bob's age would be double Cindy's age, so that means 2 multiplied by Cindy's age = Bob's age, or 2C = B. Your two equations are:
A - 5 = B
2C = B
Also a third equation that helps is A + B + C = 20.
Finally, here are the ages.
Alan = 11 years old
Bob = 6 years old
Cindy = 3 years old.

Answer:
No units
Step-by-step explanation:
The cost function is given by;
To find the units manufactured at a cost of $5,560
We equate the C(x) to 5560 and solve for x.
The discriminant of this equation is negative.
That is,
Hence the equation has no real roots.
This means no units can be produced at $5,560
Answer:
Step-by-step explanation:
8/16 = 27/x
8x = 432
x = 54
There is a pattern of -2, -6, so the next number is 20.
