It takes my’khiyah 40 seconds to run 1/3 of a lap. How many laps can she run in 5 minutes
kakasveta [241]
Answer:
number of laps = 5/2 = 2.5 laps 

Explanation:
First, we will need to convert the minutes to seconds.
5 minutes = 5 * 60 = 300 seconds

Now, we know that she can run 1/3 of a lap in 40 seconds. To know the number of laps that she can run in 300 seconds, all we have to do is cross multiplication as follows:
40 seconds .................> 1/3 laps
300 seconds ................> ?? laps
number of laps = (300 * 1/3) / 40
number of laps = (100) / 40
number of laps = 5/2 = 2.5 laps

Hope this helps :)

What are “like terms”? Why can we only add like terms?
SSSSS [86.1K]

Answer:

Like terms are terms whose variables are the same.

We can only add them because if they does not have the same variable you do not actually know if the variables are equivalent and you will get the wrong answer.

Step-by-step explanation:

Ex: 4z,7z,108z,45z

Ex: 4w-2h+7a-2w

You can not add 4w and 7a because you do not know what the variables equal so you do not know the true number so add or subtract by.
