Answer:
Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined . In this case, the opposite of 2x+1 is -(2x+1)=-2x-1 by the distributive property . Adding like terms, 2x+-2x+1+-1=0+0=0.
Answer:
Step-by-step explanation:
the correct answer is 3
186.99999992 and that is the correct anwser i think
8.5x-26.35=-37.35
8.5x=-37.35+26.35
8.5x=-11
X=-11/8.5
X=-1.29
Answer:

Please refer to graph attached.
Step-by-step explanation:
Given that mass of each candy in the box is 5 gm.
Mass of empty box is 20 gm.
Total grams, 
To find: A table of values and graph of the relation.
Solution:
The given equation is nothing but a Linear equation in two variables.
Let us try to create a table of values by putting some values of 'n' and then finding the values for Total grams 'T'.
Let us put 
Let us put 
Let us put 
Let us put 
Let us put 
So, the table of values becomes:

We can see that the value of T is increasing with increasing values of 'n'.
Please refer to the attached image for the graph of given equation.
As it is a linear equation in two variables, it will be a straight line. It will be an increasing positive slope graph.
