use the tape diagram to help you write an equation to represent this problem.

tape diagram with 6 sections labeled y+4 and total 42

blank boxes for equation: square (square) = square
options: y+4, y+6, 42, 5, 6, 6

Explanation:

Step1: Identify total groups

There are 6 students, so 6 equal groups.

Step2: Define each group size

Each student has $y+4$ paint tubes.

Step3: Set total equal to sum

Total tubes = number of groups × group size
$$6(y+4)=42$$

Answer:

$6(y+4)=42$
