Multiply both sides of the equation by 12
Answer:
both of them thats the answer
Step-by-step explanation:
The ages are consecutive even numbers.
The youngest child is (x+3) years old.
Every even number is 2 more than the one before it.
So the three ages are
(x + 3), (x + 5), and (x + 7).
Their sum is x+3 + x+5 + x+7 = 3x + 15
But we're told that their sum is 42, so we can write
3x + 15 = 42 <== the equation
Subtract 15 from each side: 3x = 27
Divide each side by 3 : x = 9 <== the solution
So the three ages are 12, 14, and 16.
The oldest child is 16 years old.

Since the hundred thousandths is a 1 which is less than a 5, you have to round down.
Answer:
2.056
rounded to the nearest tenth: 2.1
