11. Take the logarithm, base X.
  a² - ab = 10
Since we are given that b = a - 2, we can substitute for b to get
  a² - a(a -2) = 10
  a² - a² + 2a = 10 . . . . . eliminate parentheses
  a = 5 . . . . . . . . . . . . . . simplify, divide by 2


_____
Check: a² = 5² = 25
  ab = 5·3 = 15
  X^25/X^15 = X^10 . . . . . the answer works

What is the best estimate for the length of a bike
castortr0y [4]
<span>The average length of a bike (including the length of both wheels) is about 68 inches.For finding the true answer we must follow the following convertion rule: 1 inch is equivalent to 0.02 yard, so 68 inches equal to 1.88 yards. Consequently, the value nearest 1.88 yards is 1.5 yards, so the answer is the choice A: 1.5 yards. </span>
