Question

2 The students in Mr. Martinez's class counted by 6s. The first student said 6, the second student said 12, the third student said 18, and so on.

How many students counted to get to 126? _______________

How do you know?

Answer 1

21

Explanation:

I set it up as a table and found the equation. With increasing student counting it increases by six. So 6 times the number of students of counting gives you your output (y).

Input | Output Equation: 6x = y

1 6

2 12

3 18

4 24

5 30

.... .....

19 114

20 120

21 126

Hope this makes sense
