Sam is 5 years old...his older brother Tom is 3 times as old as Sam...when Sam is 20...how old will Tom be?

Let m be Marian's age, d Diana's age and c Carlos age.

• sum of ages is 17: m+d+c=17
• two years from now Marian will be twice as old as Diana: m+2=2*(d+2) so m+2=2d+4 so 2d=m-2 or d=(m-2)/2=m/2-1
  
• Carlos will be half as old as Marian 4 years from now: c+4=1/2(m+4) or c+4=m/2+2 or c=m/2-2
  
• now: m+d+c=m+m/2-1+m/2-2=17
• 2m=17+3=20
• m=20/2=10 years
• d=m/2-1=5-1=4 years
• c=m/2-2=5-2=3 years

Marian is 10 years old, Diana 4 years old and Carlos is 3 years old.

I hope I helped :)

Todd is 4 years old.

Let Tom's age = X
Let Todd's age = Y

From the given facts:

X = 5Y

and

X + 7 + 6 = 3 ( Y + 7 )
X+13 = 3Y + 21
X = 3Y + 8

So if:
X=5Y
and
X=3Y+8

Then:
5Y=3Y+8
2Y=8
Y=4

I hope that helps.

5 - 6 years difference is ok, once both parties are about 26 and 21. But a 20 year old dating a 14 year old is not to cool. Ether way, older boy or girl, there is a since that the older one can't communicate on their own level. If the younger of the two is far more mature for their age they will miss things that happen when dating a person of their own age. The mom and dad of the younger of the couple will loose some control; being the older one will feel as they can handle things on an adult level. It will be hard to set boundaries that the older one will stick with, but the younger should live by. Such as in by a set time, homework, projects for school. The older of the couple will push for their time "alone" which will take from the younger of the two tending to their duties. Sorry, put your foot down and save a lot of drama in your future, just say "NO, NO, NO".

Let the brother's age be x:
16years for Mary = 4x years for Brother

From equation: 4x = 16
x = 4
Therefore, the brother is 4 years old.

Mary Brother
16 4
After 4 years + 4 4
20 8
After the next 4 years + 4 4
24 12

24 is twice as old as 12; therefore for the sister to be twice as old as brother she will 24years when her brother is 12 years.

Or by calculation;

If 4 is the age for the brother, when the sister is 16, and y years will pass for the to be such that the sister is twice as old as the brother, then;

16 + y = 2(4 + y)
16 + y = 8 + 2y
16 - 8 = 2y - y
8 = y
Therefore, 8 years elapse before the sister is twice as old as the brother.

Sister will be: (16 + 8) = 24years
Brother will be: (4 + 8) = 12years

It depends on the manufacturing battery life time. Generally they are 3 to 5 years or 5 to 7 years or 8-10 years. Nevertheless due to high cost of batteries most client opt for use 3 to 5 year life time. A simple internet search will give you the specification and from there you can decide what to do. If it is 3 to 5 years life time it is advisable to change the whole set. Otherwise you can replace the 3 batteries as a temporary solution. However it is most likely that after 3 to 6 months you will have some other bad cells.

The Tomtom map updates are available by subscription from www.Tomtom.com Under most conditions it is not really necessary to update every year. The updates run about $40 per year. The best option on most of the small GPS units under $100 is to use it for 2-3 years and then just sell the older one and buy a new unit. The reason I say this is because the map updates only update the maps not the features or the software. The newer units will have new features and options for the same price as you would get with buying a map update your the older unit.

I hope this helps, if so please rate our solution.

Just a shot in the dark- I think your main projection lamp is going bad- If the set is more than a year or 2 old it can happen. Unfortunately they are a little expensive.
