Answer:
(A) and (C)
Step-by-step explanation:
To find equivalent expressions, we need to first find the value of the original, [tex]-3+(-5)[/tex]
Adding a negative is the same as subtracting a positive. So, it's equivalent to [tex]-3-5[/tex], which is [tex]-8[/tex].
Now we test all the other expression to see if they equal -8.
A:
[tex]-2 + (-6)\\\\-2-6\\\\-8[/tex]
So this works.
B:
[tex]1 + (-7)\\\\1 - 7\\\\-6[/tex]
So this doesn't work.
C:
[tex]5+(-13)\\\\5-13\\\\-8[/tex]
So this works.
D:
[tex]3+(-5)\\\\3-5\\\\-2[/tex]
So this doesn't work.
Hope this helped!
