The expression that represents the tape diagram are B, C and E.
Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
From the tape diagram:
The expression is,
87 - (39 + 4x).
(A).
There are 87 children and 39 adults at a show. The seating in the theater is split into 4 equal sections.
The expression: (87 + 39)/4x.
(B). There are 87 first-graders in after-care. After 39 student are picked up, the teacher put the remaining students into 4 groups for an activity.
The expression: 87 - (39 + 4x).
(C). Lin buys a pack of 87 pencils. She gives 39 to her teacher and shared the remaining pencils between herself and 3 friends.
The expression: 87 - (39 + 4x).
(D). Andre buys 4 packs of paper clips with 39 paper clips in each. Then he gives 87 paper clips to his teacher.
The expression: 4(39) - 87
(E). Diego's family spends $87 on 4 tickets to the fair and a $39 dinner.
The expression: 87 - (39 + 4x).
Therefore, the equivalent expressions are B, C and E.

Answer:
boxes 2, 3, and 5
Step-by-step explanation:
because giving 87 pencils when that your total doesn't make sense neither doesa theatre being split into 4 equal sections when there are five sections and they arent even equal
Answer:
Expression = 2 × 7 + 3 + 3
Evaluation of the expression = 20
Step-by-step explanation:
Number of laps Glenn swam every morning = 2
Number of days for which he swam these laps = 7 days
⇒ Number of laps swam in a week = 2 × 7
Number of laps swam with his friend on Tuesday = 3
Number of laps swam with his friend on Thursday = 3
So, Expression that show the number of laps he swam during the week = 2 × 7 + 3 + 3
By evaluating the above expression, the total number of laps he swam that week = 14 + 3 + 3 = 20 laps
