Answer:
The ages of the children are 6, 9 and 12.
Explanation:
Let x= the age of the youngest child.
If the oldest child is twice the age of the youngest, the age of the oldest child is twice x or 2x.
If the middle child is 3 years older than the youngest, the age of the middle child is x+3.
If the sum of their ages is 27, then
x+2x+x+3=27aaa(Combine like terms)
4x+3=27aaa
aa−3a−3aaa(Subtract 3 from both sides)
4x=24
4x4=24aaa(Divide both sides by 4)
9x + 4 ≤ 58
=> 9x ≤ 58 - 4
=> 9x ≤ 54
=> x ≤ 54/9
=> x ≤ 6
______________
1/6x − 2 > 3
=> 1/6x > 3 + 2
=> 1/6x > 5
=> x > 5×6
=> x > 30
It’s c and i know cause i got it right
Answer:
