One expression that Gary can use,where y is the amount of food eaten in a year and x the amount of food eaten in a weeks is:
y=x*52
but we actually know that the cats eat one third of 3 1/2 pounds, that is:
So we can substitute this:
y=

which is y=7*13=91
So we actually know that the cats eat 91 pounds of food a year!
I can only assume that you meant, "Solve for x:"
Apply the exponent 3/2 to both sides of this equation. The result will be
3/2
343 = x/6.
Multiplying both sides by 6 isolates x:
3/2
6*343 = x Since 7^3 = 343, the expression for x
can be rewritten as
3/2
6*(7^3) = x which can be further simplified, as follows:
x = 6^(3/2)*7^(9/2), or:
x = 6^(3/2)*7^(8/2)*√7, or
x = 6^(3/2)*7^4*√7
