Answer:
the oldest sibling is 12 years old.
The middle child is 9 years old.
The youngest child is 6 years old.
Step-by-step explanation:
Let the age of the youngest child be x
Then the oldest child will be 2x.
The middle child will be x + 3.
Since the combined age is 27;
x + 2x + x + 3 = 27
4x = 27 - 3
x = 24 / 4
x = 6
now 2x = 12 and x + 3 = 9
First get common denominators 2/3+x=-15/6-5/6
second simplify 2/3+x=-20/6
third get x alone x=-20/6-4/6
fourth simplify and reduce x=-24/6 x=-4
Are you sure you’re writing the equation right?

Answer:
2.5 years
Step-by-step explanation:
Amount= $8036
Principal= $7000
Rate =5.6%
t= ?
n= 2
A= P(1 + r/n)^nt
8036= 7000(1 + 0.028)^2t
1.148= (1 + 0.028)^2t
log(1.148) = log (1 + 0.028)^2t
0.05994= 2t × 0.01199
t= 2.5 years
