We add all these mixed numbers together:
1 1/2 + 2 3/4 + 2 1/3
It will be easier to convert the mixed numbers into improper fractions:
3/2 + 11/4 + 7/3
Now we have to find the common denominator which is 12:
18/12 + 33/12 + 28/12 = 79/12 = 6 7/12
The answer is 6 7/12 hours.
Okay we’re gonna do the order of PEMDAS. Here is my work! I hope you have a great day or night or whate it is for you.

12-10= 2 cm
I think we need a coordinate grid for that,,
B is just simply the y intercept
