Answer 5

P.E.M.D.A.S., ever heard of it?

P - Parenthesis

E - Exponents

M - Multiply

D - Divide

A - Add

S - Subtract

This is the order of operations. A easy way to remember it is by saying the phrase "Please excuse my dear Aunt Sally."

Answer 6

yes!

Answer 7

So can you tell me what you think the answer is? Give me a reason as well so I know your not just guessing.

Answer 8

i think it is C because when i started working it out the other answer have you doing 1/8 first though you dont do that yet

Answer 9

If you are still struggling I can understand, this is a tricky question.

The work is shown below:

( x + 35 ) = -7

35 - ( x + 35 ) = -7 - 35

x = -42

I would say all the answers are wrong, however they are looking for C.
