Answer 1

The student will be 63 inches tall in sixth grade.

Step-by-step explanation:

To calculate the height of a student in sixth grade, we need to find out how much the student will grow from kindergarten to sixth grade and add that to their initial height. Let's break it down:

1. The average growth rate of an elementary school student is 2 1/2 inches per year.
2. In kindergarten, the student is 4 feet tall, which is equal to 48 inches.
3. From kindergarten to sixth grade, there are 6 years.
4. To find out how much the student will grow in 6 years, multiply the growth rate per year (2 1/2 inches) by the number of years (6). 2 1/2 inches * 6 = 15 inches.
5. Add the growth in inches to the initial height to find the final height. 48 inches + 15 inches = 63 inches.

Therefore, the student will be 63 inches tall in sixth grade.

Answer 2

Answer: 5 feet 3 inches (63 inches)

_____________________

Equation: y=2.5(6)+4(12)

2.5(6)= 15
4(12)= 48

15+48= 63

63 inches convert to feet is 5 feet and 3 inches
