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
oldest is 12
middle is 9
youngest is 6
all add up to 27
Step-by-step explanation
idk if i did this right but i did 27 -3 =24
then i divide 24 by 2 which is twelve (the oldest's age)
then 12 divided by 2 is 6 which is the age of the youngest one
6 + 3 is 9, which is the age of the middle one.
in scientific notation (also called standard form).
i think the answer is 2
The answer is "8 hours"
by the given value we create the equation that is:
This relationship is a function
While a function may not have two output values (y) assigned to the same input value (x), it may have two input values (x) assigned to the output value (y).
The table follows that rule
