Question

Mariana has 3 pairs of glasses. How
many lenses are on all of Mariana's
glasses?

Answer 1

6

Explanation:

A pair of glasses usually contains 2 lenses. The equation y=2(x) is equal to the amount of lenses she would have. If y=total lenses and Mariana has 3 pairs then that means y=2(3) and 2(3)=6. Therefore y=6.

This is assuming that the glasses are single lense.

Answer 2

Answer: 6 lenses

Explanation:

1 pair of glass=2 lenses

3 glasses=3 pair of glasses

3 pairs of glasses*2 lenses/1 pair of glass=6 lenses in 3 pair of glasses
