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
\[a+17=35\]
Find the value of
\[a\] that makes the equation true.
\[a=\]

Answer 1

The top tape equals the bottom tape, so a + 17 = 35 (choice B).
Solve: a = 35 − 17 = 18.
