Question 751452: Currently Doris is one year older than twice Arthurs age. In ten years time the sum of their ages will be 39. Determine their current ages now.
Answer by kmadison(2) (Show Source):
You can put this solution on YOUR website!Equation for Arthur's age in respect to Doris: D = 2A + 1
After ten years time
(D + 10) = 2(A + 10) + 1
So we need to find D + A = 39, or (D + 10) + 2(A + 10) + 1 = 39 = 2D + A + 31 = 39
We have 2 equations, 2 unknowns so we eliminate 1 variable
We know that D = 2A + 1 Therefore 39 = D + 30 => D = 9
9 = 2A + 1 => 2A = 8 or A = 4
So now, Doris is 9, and Arthur is 4.
Question 751250: John is four years younger than clement. if their ages are in ratio of 7:9. What is the age of john
Answer by ankor@dixie-net.com(15656)  (Show Source):
You can put this solution on YOUR website!John is four years younger than clement.
if their ages are in ratio of 7:9.
What is the age of john
:
let x = the multiplier
then
7x = J's age
and
9x = C's age
:
"John is four years younger than clement."
7x = 9x - 4
4 = 9x - 7x
4 = 2x
x = 4/2
x = 2 is the multiplier
then
7(2) = 14 yrs is J's age
:
:
You can confirm this by finding C's age
9(2) = 18 is C's age, 4 yrs older than J

Question 750687: At present, Gilbert's age is 30% of his father's age. Thirty years from now, Gilbert's age will be 60% of his father's age. How old is Gilbert now?
Answer by ankor@dixie-net.com(15656) (Show Source):
You can put this solution on YOUR website! At present, Gilbert's age is 30% of his father's age.
g = .3f (using the decimal equiv of percent)
:
Thirty years from now, Gilbert's age will be 60% of his father's age.
g + 30 = .6(f+30)
g + 30 = .6f + 18
g = .6f = 18 - 30
g = .6f - 12
Replace g with .3f
.3f = .6f - 12
12 = .6f - .3f
12 = .3f
f = 12/.3
f = 40 yrs is Dad's age
How old is Gilbert now?
g = .3(40)
g = 12 yrs
:
:
Check this
12 + 30 = .6(40+30)
42 = .6(70)

You can put this solution on YOUR website!r for Ross age, and h for Holly age.
 , Ross is five years older than twice his sister Holly's age.
 , The difference in their ages is 14 years.
I would take r from the first equation and substitute into the second equation, and solve for h. You could then use what you found for h to find value of r.
and continue...
Answer by ankor@dixie-net.com(15656) (Show Source):
You can put this solution on YOUR website!Ross is five years older than twice his sister Holly's age.
r = 2h + 5
:
The difference in their ages is 14 years.
r - h = 14
r = (h+14); you can use this form for substitution
How old is Holly?
Question 750684: A person is 50 years old. His son is 24 years old. How many years ago was the father three times as old as his son?

Question 750776: If a group of 6 people have an average age of 21, and each person is half the age of the next person, what are the ages of the 6 people
Answer by timvanswearingen(106)  (Show Source):
You can put this solution on YOUR website!Let x be the age of the youngest of the 6 people. Then the rest of their ages are 2x, 4x, 8x, 16x, and 32x.
Since their average age is 21, 21*6=126. The sum of their ages is 126.
Divide both sides by 63:
So their ages are 2, 4, 8, 16, 32, and 64
Question 750646: When Matthew is 12 years old his mother is 3 times as old. How many years must pass before his mother is twice as old? How many years ago was she 7 times as old?
Answer by ankor@dixie-net.com(15656) (Show Source):
You can put this solution on YOUR website!When Matthew is 12 years old his mother is 3 times as old.
Matt = 12, Mother = 36
:
How many years must pass before his mother is twice as old?
let y = no. of years for this to be true
y + 36 = 2(y+12)
y + 36 = 2y + 24
36 - 24 = 2y - y
12 = y
This will be true in 12 yrs (Mom will be 48, Matt will be 24)
:
How many years ago was she 7 times as old?
let z = no. of yrs for this to be true
36-z = 7(12-z)
36 - z = 84 - 7z
-z + 7z = 84 - 36
6z = 48
z = 8 yrs for this to be true. (Mom will be 28, Matt will be 4)

You can put this solution on YOUR website! The sum of the ages of two brothers is 38 years. Four years ago, the age of the elder brother was the square of the younger brother's age.Find their ages.
------
Equations:
a + b = 38 years
a-4 = (b-4)^2
--------------------
Rearrange:
a = 38-b
Substitute for "a" and solve for "b":
(38-b)-4 = b^2 - 8b + 16
b^2 - 7b -18 = 0
----
(b-9)(b+2) = 0
----
Positive solution:
b = 9 (one of the brother's age)
Solve for "a":
a + b = 38
a + 9 = 38
a = 29 (age of the other brother)

Question 748610: The difference between the present age of the father and son is 30. 5 years ago, the son age is one seventh of the father age. find their present age.
Answer by tommyt3rd(606) (Show Source):
You can put this solution on YOUR website!The difference between the present age of the father and son is 30 means
F-S=30
which we rewrite as F=S+30
5 years ago, the son age is one seventh of the father age means
7(S-5)=F-5
which we rewrite as F=7S-30
Now we can write
S+30 = 7S-30
6S =60
S=10
and so F=S+30=10+30=40
Sons is 10 and father is 40

Question 748158: Crisner is 3 years older than her niece Josephine. In 7 years she will be six seventh of her age. How old are they?
Answer by ankor@dixie-net.com(15656) (Show Source):
You can put this solution on YOUR website!): Crisner is 3 years older than her niece Josephine.
In 7 years she will be six seventh of her age.
How old are they?
:
Let c = C's age now
Let j = J's age
;
Write an equation for each statement
:
"): Crisner is 3 years older than her niece Josephine."
c = j + 3
:
"In 7 years she will be six seventh of her age."
j + 7 =  (c+7)
Get rid of that annoying fraction, mult both sides by 7
7(j+7) = 6(c+7)
7j + 49 = 6c + 42
7j = 6c + 42 - 49
7j = 6c - 7
replace c with (j+3) from the 1st statement
7j = 6(j+3) - 7
7j = 6j + 18 - 7
7j - 6j = 11
j = 11 yrs is J's age
then
11 + 3 = 14 yrs is C's age
;
;
see if that works
j + 7 = (c+7)
11 + 7 = (14+7)
18 = (21)
7 cancels into 21
18 = 6(3)

Question 748241: If Adam is 15 years younger than Alicia and in 6 years Alicia will be twice as old as Adam, how old is Adam?
Answer by timvanswearingen(106) (Show Source):
You can put this solution on YOUR website!Let x represent Alicia's age now.
Adam's age would be x-15
In 6 years, Alicia will be x+6 and Adam will be x-15+6 or x-9.
At that time, Alicia will be twice as old as Adam.
Thus, 2 times Adam's age should be equal to Alicia's age:
Distribute:
Subtract x from both sides:
Add 18 to both sides:
Adam's age was represented by x-15, so plug in 24 for x:
Adam is 9 years old.
