Define their age
---------------------------------------------------------------------------------------
Let Jim be x years old
Jim = x
Father = x + 31 ← Jim is 31 years younger than the father
Grandfather = x + 70 ← Grandfather is 70 years older than Jim
---------------------------------------------------------------------------------------
Combined age is 137, find x
---------------------------------------------------------------------------------------
x + (x + 31) + (x + 70) = 137
x + x + 31 + x + 70 = 137
3x + 101 = 137
3x = 137 - 101
3x = 36
x = 12
---------------------------------------------------------------------------------------
Find their age
---------------------------------------------------------------------------------------
Jim = x = 12
Father = x + 31
Father = 12 + 31
Father = 43
Grandfather = x + 70
Grandfather = 12 + 70
Grandfather = 82
---------------------------------------------------------------------------------------
Answer: Jim = 12 ; Father = 43 ; Grandfather = 82

Answer:
Jim is 5, Dad is 20
Step-by-step explanation:
Since dad is 4 times as old as Jim that means 5 x 4=20 and in ten years Jim will be 15 and Dad will be 30 and 15 x 2 is 30.
Hope this helps!
Answer: There are 24 different outcomes possible.
Step-by-step explanation:
Since we have given that
One dollar coin has 2 possible outcomes
i.e. head and tail
Two dollar coin has 2 possible outcomes,
i.e. head and tail
A six sided die are tossed has 6 possible outcomes,
i.e. 1,2,3,4,5,6
So, total number of different outcomes are given by
Hence, there are 24 different outcomes possible.
If we take the 68.73 to be the 100%, then what is 12 in percentage of that?
since in this case, the tip seems to be a percent of the bill
so
solve for "x"
