which expression is equivalent to
This is a topic that many people are looking for. thevoltreport.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, thevoltreport.com would like to introduce to you What are equivalent expressions. Following along are instructions in the video below:
the equivalent expressions equivalent expressions hahaha pretty much we can represent equivalent expressions by using one of these little signs that kind of looks like little railroad tracks which we call an equal sign and when dealing with this equivalent expressions pretty much mean that this side equals that side meaning that two expressions algebraic or you know numeric are gonna have exactly the same value so lets take a look at a couple equivalent expressions
seven equals seven so therefore I can say that value on the left side of the equal sign is equal to the value of on the expression on the right side which is seven equals seven fair enough right a lot of times we actually looked at this I can do three times four is equal to four times three right this is when we use the commutative property we said that three times four was
equal to four times three the values on the left and right side are equal to each other what else have we talked about so far we said a plus zero was equal to a where a represented any real value or any real number but since theyre a they have to be exactly the same so we said that a plus zero equals eight now I know they dont look like the same but what
we talked about was the value of both sides of this equation are exactly the same therefore they are equivalent expressions so you know a lot of times when were talking about equivalent expressions its just a way to say that you know the left side is equal to the right side and they dont always have to look alike right so one thing that you know will start when we start looking into equations we
could say that a equals nine this is an expression meaning the value of a is equal to nine so this side equals this side well if this side equals this side then what is the value I have to be well the value of a has to be nine right therefore we can say a is equal to nine or the same value as nine so theres just a quick little demonstration of the equivalent expressions
