Anna weighs 54 pounds. Peter weighs x pounds. Write an expression for their combined weight.
"combined" means to add them together: 54+x
To write an expression for their combined weight, you need to take into account Anna's weight, which is given as 54 pounds, and Peter's weight, represented by the variable x.
The combined weight of Anna and Peter would be equal to the sum of their weights. Hence, the expression for their combined weight can be written as:
54 + x
So, the expression for their combined weight is 54 + x pounds.
