Rama09 [41]
Let Mia's score be x.  Then, Erick scored 10 more than Mia, so his score is x+10.  Isabelle scored 16 less than twice Mia's score, so her score is 2x-16.  We can see that x + x + 10 + 2x - 16 is the sum of these variables, so the expression represents the total of their scores in this scenario.  Moreover, we recall that the variable in the expression, x, represents Mia's score.

To simplify this expression, we add up the variables and the numbers separately, giving us x+x+10+2x-16 = (x+x+2x) + (10-16) = 4x-6.  Therefore, in simplified form, the expression is equal to 4x - 6.  The constant term in an expression is the term not multiplied by a variable, so in this case, it is -6.
