Answer:
1 : 12 : 4
Step-by-step explanation:
Carl = C
George = G
Alex = A
A = 12 + G , G = A - 12
C = 3 * A
C + G + A = 68
Substitute new values for G and C into equation
3 * A + A - 12 + A = 68
5A - 12 = 68
Add 12 to both sides of the equation
5A = 80
A = 16
Alex is 16 years old
Carl is 48 years old
George is 4 years old
4 : 48 : 16
Simplify
2 : 24 : 8
Simplify further
1 : 12 : 4
Hope this helps :)
Answer:
Step-by-step explanation:
Let George's age be x years
Alexis is (x+12)years
Carl is 3(x+12) years =(3x +36)years
Sum of their ages =68
x+x+12+3x+36=68
5x+48=68
5x=68-48=20
x=20/5= 4years
George is 4 years old
Alexis is 4+12 =16 years old
Carl is 3 times alexis age = 3×16= 48 years old
Ratio of George to Carl to Alex is 4:48:16
Reduce to lowest term since 4 can still go through
Ratio =1:12:4

H(x) = x - 7
g(x) = x^2
(g * h)(x) = x^2 (x - 7)
(g * h)(5) = 5^2 (5 - 7)
80* 1/4= 20
80-20= 60

I hope this is correct, good luck!
Answer:
2(10 + 12)
Step-by-step explanation:
20 + 24
=> 2(10 + 12)
Therefore, 2(10 + 12) is our expression with 2 as a factor for each term.

Not sure if you are just looking for equations but it would be written as
1/4(r+10)=r-4
Solving would be
1/4r+10/4=r-4
26/4=3/4r
r=26/3 or 8.66
