Question

The tape diagram represents an equation.
A tape diagram with two tapes of equal lengths. The top tape is split in 2 unequal parts. The first part is labeled, "A," and the second part is labeled 17. The bottom tape is labeled 35.
\[a\]
\[17\]
\[35\]
Write an equation to represent the tape diagram.
Choose 1 answer:
A
\[a-17=35\]
B
\[a+17=35\]

Answer 1

The whole top tape is A + 17 and it equals the bottom tape 35, so the equation is
A + 17 = 35.
(Answer: B; A = 18.)
