Possible Answers:

Both  and 

Correct answer:

Explanation:

A coefficient is a number or symbol that is being multiplied by an unknown. In this case,  is our unknown and it's being multiplied by , thus  is our coefficient. 

Example Question #12 : Identify Parts Of An Expression Using Mathematical Terms: Ccss.Math.Content.6.Ee.A.2b

Solve for :

 

Possible Answers:

Correct answer:

Explanation:

The equation  asks us to identify which number, , plus  is equal to .

In order to solve this equation, we need to isolate the  variable on one side of the equals sign. We will do this by performing the opposite of the operations that were done on the variable,. We need to remember that whatever we do to one side of the equals sign, we have to do to the other. 

Since  was added to the variable, we can subtract  from both sides of the equation. 

Simplify by dropping the  because it has not numerical value; therefore:

We can check to make sure we have the correct value for  by plugging  into the original equation; thus:
