To determine the number of different variables in an expression, you need to identify the unique letters or symbols that represent unknown values.
Let's go through each question one by one and break down the expressions to find the variables:
1. In the expression 5g^2 - 2h + 9, there are two variables: g and h.
2. In the expression -3 + 2s, there is only one variable: s.
3. In the expression 32y^2 - 16, there is only one variable: y.
4. To represent the amount of money you will earn if you work x number of hours at a rate of $15 per hour, you would multiply the number of hours (x) by your hourly rate. The expression would be: 15x.
5. To represent the remaining amount of money after entering the theme park and buying d amount of drinks, you would subtract the cost of admission ($50) and the cost of the drinks ($10 multiplied by d) from the initial amount of money ($100). The expression would be: 100 - 50 - 10d.
