Answer:

B.

Step-by-step explanation:

Hello

step 5 is wrong

because 2 + 10/2

[tex]2+\dfrac{10}{2}=\dfrac{4}{2}+\dfrac{10}{2}=\dfrac{14}{2}[/tex]

is different from (2+10)/2

[tex]\dfrac{2+10}{2}=\dfrac{12}{2}[/tex]

as there is no parentheses you have the follow the correct priorities

division first, do 10/2=5 and then the addition 5 + 2 = 7

hope this helps

Answer:

Step 5 is incorrect

Step-by-step explanation:

You dont have to solve this to figure it out.

Remember the Order of Operations:

         1. Parenthesis

                 2. Exponents

                        3. Multiplication & Division

                              4. Addition & subtraction

You can see that in step 5, they added instead of divided.

It should have gone from 2 + 10 / 2  ----->   2+ 5. And then its a different final solution as well.

Hope this helps! If not, comment on it and let me know about my error. Have a great day!!
