Using the rule of logarithms
x = n ⇔ x =
note that ln x is to the base e
Given
ln(x + 5) = 7, then
x + 5 = ( subtract 5 from both sides )
x = - 5 ≈ 1091.63 ( nearest hundredth )

Answer: 8 hours
Step-by-step explanation:
Let x be the time taken by each person to paint the fence.
Given: Tom and Becky can paint Jim's fence together in 12 hours.
