Question

On a distant planet, Ralph ran into a creature with multiple arms and multiple legs. Each arm has 6 fingers and each leg has 9 toes. On any one of these creatures, the total number of fingers and toes, D, can be described with the equation D = 6x + 9y. In this equation, what does the variable x represent? A. the number of arms the creature has. B. the number of legs the creature has. C. the number of fingers the creature has. D. the number of toes the creature has.

Answer 1

Since D represents the total number of fingers and toes the creature has, and the creature has 6 fingers on every arm, the 6 in "6x" must be referring to the 6 fingers, and so x must be referring to the number of arms.

So the answer is A. the number of arms the creature has

Answer 2

The total number of fingers and toes of the creature:
D = 6 x + 9 y
In this equation the variable x represents :
A ) the number of arms the creature has.
