To find the age of tom we will use the expression 20*3 because tom is three times as old as Sam.
so the answer is 60
Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700
Step-by-step explanation:
The answer is A, recursion uses the previous answer to solve the next answer so:
If a sub 1 is 12
Then a sub 2 = 12 + 4 = 16
Therefore a sub n = a sub (n - 1) + 4
