D will be the answer shifter left 1 point
Answer:
A. True
Step-by-step explanation:
One of the ways to check this is solving each side of the equation.
(5+4)+10=5+(4+10)
Remember PEMDAS.
Parenthesis first.
(9)+10=5+(14)
Now, you can drop the parenthesis and add the numbers together.
9+10=19
5+14=19
19=19
This is a true statement.
Hope this helps!
If not, I am sorry.
8-2=6
10+6+3=19
I’m not sure if you are allowed to do it that way so I can find other ways if needed
81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
-2 should be correct. It is an input for that given graph.
