For system to have infinite solutions, both equation must be similar.
Noticed that second is the first equation times 3:
3[ 2x - 4y = 18]
6x - 12y = 54
So you should fill in 12 in box.
This is volume of a sphere.
Inverse variation:
k is a constant
Use the given information (when x=4 y=4) to find the value of the constant:
Then, the given relationship has the next equation:
Use the equation above to find y when x=2:
Then, when x=2, y=8
If the can is 20oz and cost $25.40, the price per ounce would be:
price = $25.40
ounce = 20oz
so:
which comes out to be:
$1.27/oz
So each ounce of tomato sauce costs $1.27!
