Assuming we're working with the base 10 log, you can solve by making both sides exponents to a base of 10 (which cancels the log on the right side):
Answer:
1/12 is the correct answer.
Step-by-step explanation:
Answer:
- Equation 3y = -42
- Solved: y = -14
Step-by-step explanation (to solve the equation):
- Divide each side by 3 to cancel out the 3 next to y. It should now look like this: y = -14

Answer:
7.5 laps
Step-by-step explanation:
First, you wanna figure out how many yards is in one lap
to do this, you would multiply 100 and 4 (four because there's four equal sides in one lap)
100 x 4 = 400
You know their speed is 5 yards per <em>second,</em> so you wanna find out how many seconds they will be running
to do this, you multiply 60 (sixty because there's sixty seconds in one minute) and 10 (ten because that's the given amount of minutes)
60 x 10 = 600 seconds
now to found out <em>how much</em> they will run in 10 minutes you will multiply 600 by 5
600 x 5 = 3000 yards
now to find how many laps this is, you can divide 3000 yards by 400 yards
3000 ÷ 400 = 7.5 laps
