solve for "w", to find the wind's speed rate,
so hmmm what's the plane's rate? well 420 - w = r :)
Answer:
answer is present in the attachment
Step-by-step explanation:
you have misquoted the amounts for the opening balances of Supplies and Deferred Revenue. I checked the internet for the right amounts and those are $400 for Supplies and $300 for Deferred Revenue. I have attached a picture to answer your question. Please find the attachment with the name "Answer".
However, I have also solved the question with the amounts that you provided and have attached a picture for it with the name "Answer 2".
X is twenty
2x+6x+20=180
8x=160
X=20
Answer:
Step-by-step explanation:
we are given that 1 angle equals 27 and the other two are equal.
180-27=153. and the other two are equal so they each equal 76.5 (153 divided by 2) now since one of the angles is supplementary with angle x, they together must equal 180 so: 180-76.5=x, x=103.5
Domain – All of the values that go into a relation or a function are called the domain. Range – All of the entities (output) which emerge from a relation or a function are called the range. All input values that are used (independent values) forms the Domain set.
