Divide by e^2x to get 6 = 7e^2x. Then take the natural log of both sides so you now have ln6 = ln7e^2x. Use laws of logs to make this ln6=2xln7e. Rearrange for x to get x=(ln6)/(2ln7e) and plug it into your calculator.
Answer:
3 miles per hour
Step-by-step explanation:
We need to subtract the two numbers to find the difference in speeds
4/5 - 3/4
We need to get a common denominator of 20
4/5 *4/4 - 3/4 *5/5
16/20 - 15/20
1/20
The car going 4/5 miles per minute is going 1/20 miles per minute faster than the car going 3/4 miles per minute.
The question asks for miles per hour, not miles per minute. We know that there are 60 minutes per hour.
1/20 miles per minute * 60 minutes / hour
60/20 miles/hour
3 miles/ hour
The car going 4/5 miles per minute is going 3 miles per hour faster than the car going 3/4 miles per minute.
The exponent indicates how many times the base is used as a factor.
Answer:
24
Step-by-step explanation:
simplify 8/10 into 2/5 then 2/5 of 30 is 24
