(I assume the two different name things, isaac&dominic, is a mistake since there isnt any information for Dominic)
First, let the number of skis rented by x and the number of snowboards rented by y. We can then assemble the first equation from the amount of money made from the rentals.
44x + 58y = 2232
The second equation can come from the fact that 9 more skis were rented than snowboards.
y = x - 9
Therefore our system is:
44x + 58y = 2232
y = x - 9
The inverse is f¯¹(x)=x/7.
The answer is 6/40. All the others equal 1/5.
The formula for the volume of a cube is
, where s is the side length. Then, just do 9 to the third power, or 9*9*9, which equals 729.
