121x1/5=121/5
For this case we propose a system of equations:
x: Variable that represents the amount of hours that Olivia's mother drove
y: Variable that represents the amount of hours that Olivia's father drove
So, we have:

From the first equation we have:

Substituting in the second equation:

Thus, Olivia's father drove 3 hours.

Olivia's mother drove 11 hours.
Answer:

Answer:
He can purchase a maximum of 6 large candles.
Step-by-step explanation:
If he purchases 6 large candles and 14 small candles:
$5.00 x 6 = $30.00
$3.50 x 14 = $49.00
$49.00 + $30.00 = $79.00
A square area=legnth times width
but for a square, legnth=width so
area=legnth^2
are=49
49=legnth^2
square root of both sides
7=legnth
the answer is 7
18.
18 x 3 - 14 = 40
