Let me work through each problem step by step.
Problem 1:
Mr. Swanson has c students. He picks up 5 new students.
- Algebraic Expression: c + 5
- If there were 27 students (c = 27): 27 + 5 = 32
Problem 2:
Pratap has six times as many coins as Yoshiko. Yoshiko has y coins.
- Algebraic Expression: 6y
- If Yoshiko has 47 coins: 6 × 47 = 282
Problem 3:
Ayana runs 13 laps less than Emma. Let e = number of laps Emma runs.
- Algebraic Expression: e - 13
- If Emma runs 32 laps: 32 - 13 = 19
Problem 4:
Nicki's age is the quotient of Granny's age and six. Let g = Granny's age.
- Algebraic Expression: g ÷ 6 or g/6
- If Granny is 72: 72 ÷ 6 = 12
Problem 5:
8th grade has 2/3 of the number of students in 7th grade. Let s = number of 7th grade students.
- Algebraic Expression: (2/3)s or 2s/3
- If 7th grade has 96 students: (2/3) × 96 = 192/3 = 64
Let me verify my calculations using code.
