Question

Ruby is cooking a turkey for Thanksgiving. The turkey needs to cook for 10 minutes per pound, and then an additional 45 minutes.

Select the expression that represents how long the turkey should cook.

O (10x)45
O 10 + x + 45
O x + 45
O 10x + 45

Answer 1

The correct expression for the cooking time of the turkey is 10x + 45, where x represents the weight of the turkey in pounds. You multiply the weight by 10 minutes and then add an extra 45 minutes.

Step-by-step explanation:

The expression that represents how long the turkey should cook is 10x + 45. If x is the weight of the turkey in pounds, then the turkey needs to cook for 10 minutes for each pound it weighs. After cooking it based on weight, an additional 45 minutes is needed, regardless of the turkey's weight. Therefore, the total cooking time is 10 minutes multiplied by the turkey's weight in pounds (10x) plus an extra 45 minutes (+ 45).

To understand how expressions work, let's look at these examples:

• Adding time units: 15 minutes + 60 minutes equals 75 minutes.
• Subtracting time units: 35 minutes - 10 minutes equals 25 minutes.
• Converting seconds to other units: 3000 seconds equals 50 minutes.

This process is similar to the calculation needed for cooking the turkey, which involves both multiplication and addition of time units.
