Step-by-step explanation:
Answer:
36 + 42 = 6(6 + 72)
Step-by-step explanation:
36 + 42 = 78 - 6 = 72 = 6(6 + 72)
To solve an exponential equation, take the log of both sides, and solve for the variable. Example 1: Solve for x in the equation . Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80).. Check: Check your answer in the original equation.
Time=10 trips * (7/12 hours/1 trip)=70/12 hours=35/6 hours.
1 hour=60 minutes, so:
35/6 hours *(60 minutes / 1 hour)=350 minutes
Answer: She spend communting 350 minutes.
