Shaquille, Lyle, and Amanda collect stamps. Shaquille has one-half the number of stamps that Lyle has. Amanda has two-thirds as

a_sh-v [17]

Shaquille and Amanda's stamps are described in terms of Lyle's, so:

Lyle's = 6x 6x+3x+2x=364
Shaquille's = 3x 13x=364
Amanda's = 4x x=28

Lyle has 168 stamps, Shaquille has 84, and Amanda has 112. 168+84+112=364

Teresa wrote this expression to describe the total distance she was going to swim during two swim classes.

frez [133]

I think the answer is the second one, Tessa wasn't sure how far she would swim during the first class. She would swim 3 laps during the second class. The question is confusing, because the equation s+3 is supposed to be the DISTANCE she swam in 2 classes. The problem didn't specify that distance equals laps, but I think the answer is correct
