x is in weeks.

Answer 6

...it's not....equality...it's inequality, @beccaboo022a

Answer 17

Dear B-B,
I have no idea how the guy did that. However, I do have a different perspective to offer regarding the doggie weight loss program. Easy subtraction reveals that the dog has to lose at least 15 pounds (90-75). Rate of weight loss is 5/4 (equivalent to 1.25) pounds/week. Dividing 15 pounds by that rate (5/4 pounds/weeks) results in the answer we wanted, in number of weeks this weight loss will require.
Including dimensions of measurements in this manner helps us determine whether or not the resulting "answer" makes sense. Note how (pounds) / (pounds per week) comes out to (weeks), as expected.
In summary, it will take at least (how many?) weeks for the dog to reach a healthy weight.

Answer 18

The name of the horse is Friday?
