Nicole finished her math assignment in 1/4 hours. Then she completed her chemistry assignment in 1/3 hours. How much more time did Nicole spend on her chemistry assignment?

1/3 of an hour (60 minutes) is 20.

1/4 of an hour is 15.

Subtract and receive 5.

So Nicole spent 5 more minutes on her chemistry assignment.

Another way to tackle this problem is to subtract the fractions after finding their common denominator (12)

4/12-3/12=1/12

1/12 of an hour is 5.

I used 2 different methods and I had the exact same answer. Hope it's helpful!

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
