Let Mia's score be [tex]x[/tex]. Then, Erick scored 10 more than Mia, so his score is [tex]x+10[/tex]. Isabelle scored 16 less than twice Mia's score, so her score is [tex]2x-16[/tex]. We can see that [tex]x + x + 10 + 2x - 16[/tex] 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, [tex]x[/tex], represents Mia's score.
To simplify this expression, we add up the variables and the numbers separately, giving us [tex]x+x+10+2x-16 = (x+x+2x) + (10-16) = 4x-6[/tex]. 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.
