Question

Which value is a solution to the open sentence? 6x – 3 = 27 A. 4 B. 3 C. 5 D. 6

Answer 1

C.) 5, Using P.E.M.D.A.S you have to multiply first, so replacing the variable X with 5, it should look like this: (6*5) -3=27.  6*5 is 30, 30 subtracted by 3 is 27.

Answer 2

An open sentence is one that becomes true (or false in varying scenarios). In this situation, that means that you would want the equation to be 27 = 27.

Therefore, the correct answer is C. 5.

This is because it creates the equation 30 - 3 = 27 which simplifies to 27=27.

Hope this helps! :)
