Answer:
Let, the age of AI be 'x' years, the age of Barb be 'y' years and the age of Cindy be 'z' years.
Let, the age of AI be 'x' years, the age of Barb be 'y' years and the age of Cindy be 'z' years. Then,
Let, the age of AI be 'x' years, the age of Barb be 'y' years and the age of Cindy be 'z' years. Then,According to question,
x= y + 7 ............(i)
z= 3y.................(ii)
ii)
Now,
x + y + z= 62 ( From question)
Replacing the value of x ans z from equation (i) and (ii)
or, y + 7 + y + 3y = 62
or, 5y + 7 = 62
or, 5y = 55
. ° . y = 11 years
Again,
Again, In equation(i)
x = y + 7
or, x = 11 + 7
. ° . x= 18 years.
Hence, the age of AI is 18 years.
Answer:
anything with a slope of 8/7
Step-by-step explanation:
the answer is B if you want it in simplist form
An= a1r^(n-1)
a7= 27(1/3)^(7-1)
= 27(1/3)^6
= (1/3)^(-3) * (1/3)^6
= (1/3)^(-3+6)
= (1/3)^3
= 1/27 #
