Answer:
Second option: [tex]x + x + 18[/tex]
Step-by-step explanation:
You know that "x" represents the Avery's weigth (in pounds).
Let be "y" the weight of Jada in pounds.
Since Jada weighs 18 pounds more than Avery, you can write this expression:
[tex]y=x+18[/tex]
The weight of them together is:
[tex]weight\ together=x+y[/tex]
Substituting, you get:
[tex]weight\ together=x+x+18[/tex]
Therefore, the expression that tells how much the two of them weigh together is the one provided in the second option:
[tex]x + x + 18[/tex]
