Vacuuming
Sarah spend 1/6 of an hour vacuuming her mom's car. That means that if we take a whole hour and divide it into 6 equal amounts of time, she spends one of these vacuuming the car. Let's figure out how many minutes that is. One hour is 60 minutes, so dividing an hour into 6 equal amounts of time means each of these is 10 minutes. So, Sarah spends 10 minutes vacuuming her mom's car.
Washing
Sarah spends 4 times as long washing the car as she does vacuuming it. Since she spends 10 minutes vacuuming, that means she spends 4 times that amount (4 x 10 = 40 minutes) washing the car. That is, Sarah spends 40 minutes washing the car.
Waxing
Sarah spends twice as log waxing the car as she does washing it. Since she spends 40 minutes washing, she spends 2 times 40 minutes (2 x 40 = 80) waxing the car. That is, Sarah spends 80 minutes waxing the car.
Total time spent on mom's car
The total time spent on the car is 10 minutes + 40 minutes + 80 minutes. That is 130 minutes. As there are 60 minutes in one hour, we can also express the answer as 2 hours and 10 minutes.
We want to isolate "m" on one side of the equation and have a number on the other side. Let's start by subtracting both sides by 5m
Now, let's subtract both sides by 11
We now have the value of m.
The next thing I'm going to do is a bit tedious, but you typically want to have the variable on the left side of the equation in the field of math. It's a good habit to develop now.
Thus, the answer is choice 3, -18. Let me know if you need any clarifications, thanks!
