Part A

For his class survey, Walden chose the question, How many people live in your home, including yourself? He asked his friend Drake to help him with the survey. Walden asked 10 students in his class the question, and Drake posed the same question to 10 more students in their class.

Based on the responses, they wrote these data sets:

Walden’s data set: 2, 2, 2, 3, 3, 3, 3, 4, 4, 4

Drake’s data set: 3, 3, 4, 4, 4, 4, 5, 6, 7, 9

Question 1

Match the equation with the correct property of equality by drawing a line.

1)
5y = 12

5y + 6 = 12 + 6

2)
3 + 4 = a

[tex]\frac{3+4}{2}[/tex] = a ÷ 2

3)
3c + 9 – 9 = 15 – 9

4)
