Lyle has 7/10 as many stamps as jeremy. if jeremy has 140 stamps. how many more stamps does he have than lyle?

Let L and J represent the # of stamps each boy has.  J = 140.  L = (7/10)(140).

Then  L = 98.

Lyle has 98 stamps, whereas Jeremy has 140.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
