Answer:

  9.5 inches

Step-by-step explanation:

The relationship is presumed to be ...

  (first week's growth) + (second week's growth) = (growth in two weeks)

  (first week's growth) + 3.43 inches = 12.93 inches . . . . . fill in the numbers

Subtract 3.43 from both sides of the equation:

  first week's growth = 12.93 inches - 3.43 inches

  first week's growth = 9.50 inches

The plant grew 9.50 inches in the first week.
