write an expression for jessica who sits in the 4th row 3rd seat. Each row has 6 seats only four rows.
To write the expression for Jessica who sits in the 4th row, 3rd seat, you can use a combination of variables and numbers. The variable "r" can represent the row number, and the variable "s" can represent the seat number within that row.
Given that there are four rows with six seats each, we can set the limits for our variables. The row number "r" can be between 1 and 4 (inclusive), and the seat number "s" can be between 1 and 6 (inclusive).
Using these variables, the expression for Jessica's seat would be:
(4th row number) * (number of seats in each row) + (3rd seat number)
Replacing the expressions with the values:
(4 * 6) + 3 = 24 + 3 = 27
Therefore, Jessica's seat can be represented by the expression 27.
