4.25+1.25*m, 5.75+0.75*m
4.25+5.75=10 and 1.25+0.75 = 2 therefore the two expressions are 2m+10
0.5m-1.5 : 4.25+1.25+m-5.75+0.75*m =0.5m-1.5 ( I'm quite sure about this one but I can't think of another answer but this )
Answer:
8
Step-by-step explanation:
5 + 2 =7
3/5 = 6/10
6/10 + 4/10=1
7+1=8
The additive identity property states that for every number a, you have

You're showing this property when you write

The answer would be 7/24
You can start by finding a common denominator. Since the lowest common denominator 3 and 8 have in common is 24 then that would be your denominator.
Then you can cross multiply 3*3= 9 and 2*8=16

16-9= 7
7/24
Then you are left with your answer:
is already in reduced terms.
Hope this helps! :3
