Answer: a = -250

Step-by-step explanation:

1. Solve the left side: 0.5a + 0.5a = a

2. Subtract 0.9a to the other side which gives: a - 0.9a = -25

3. Solve the left side again: 0.1a = -25

4. Divide 0.1a to the right side to isolate a: a = -25/0.1

5. Now divide -25 / 0.1 to get a = -250

Two stockings have different amounts of candy canes. The girl said to the boy, "if I give you one of my candy canes, we'll have
liubo4ka [24]

9514 1404 393

Answer:

  • girl: 7
  • boy: 5

Step-by-step explanation:

Let g and b represent the numbers of candy canes the girl and boy have, respectively.

  g -1 = b +1 . . . . . . girl gives to boy, they're equal

  g +1 = 2(b -1) . . . . boy gives to girl; she has double

Adding 1 to the first equation gives an expression for g that can be substituted into the second equation.

  g = b +2

  (b +2) +1 = 2b -2

  5 = b . . . . . . . . . . add 2-b, simplify

  g = 5+2 = 7 . . . . . find g

The girl has 7 candy canes; the boy has 5.
