Brianna's teacher asks her if these two expressions 3r +5 and 4r are equivalent.
Brianna says the expressions are equivalent because the value of each expression is 20 when r= 5.
Is Brianna correct? Explain your thinking.


Sagot :

Answer:

If Brianna's (I'll call her Bri in this situation) teacher says 3r + 5 and 4r are equal, you should definatly start by adding the 'r' value to the 3, which would be 8 afterwards. Bri is then incorrect because 4+5=9, and 9 is greater than 8, so Bri is wrong :'(...

Have a good day fellow lad,
